Again, thanks for your help and, of course, your articles. I dont suppose you knew my father, Leonard Calder? The Typhoon IB had four 20 mm cannons, while the earlier IA had 12 .303 machine guns. With Sabre development at an end, Napier focused on their next aircraft engine, the two-stroke diesel/turbine compounded Nomad. Napiers were good at making complex designs work and put in a great effort in making the complex Saber a success which helper win the war. https://www.amazon.com/gp/product/0971084785/ref=dbs_a_def_rwt_hsch_vapi_taft_p1_i0. An Account of Partnership Industry, Government and the Aero Engine by George Bulman and edited by Mike Neale (2002) The aircraft were to serve Napier for several years testing various versions of the Sabre engine. settings/time periods, and volumetric efficacy of Each cylinder displaced 93.2 cu in (1.53 L), and the engines total displacement was 2,239 cu in (36.68 L). A two-piece sleeve-valve drive shaft was mounted between each cylinder block and the crankcase, and it ran between the upper and lower cylinder banks. The Sabre IV incorporated a two-barrel Hobson-RAE injection carburetor and a revised supercharger with a single-sided impeller. One of the Sabre-powered aircraft was lost on 14 September 1944. I have made the corrections. The annular radiators durability was inadvertently tested on 18 December 1944 when EJ518 made a forced, gear-up landing after a hydraulic failure. Thank You! Bristol had been manufacturing radial sleeve-valve engines since 1932, and their Taurus engine had the same 5.0 in (127 mm) bore as the Sabre. The superchargers centrifugal impeller was double-sided. The Napier Deltic engine is a British opposed-piston valveless, supercharged uniflow scavenged, two-stroke Diesel engine used in marine and locomotive applications, designed and produced by D. Napier & Son. The Sabre VA was essentially the production version of the Sabre V. The Sabre VA had a takeoff rating of 2,300 hp (1,715 kW) at 3,850 rpm with 12 psi (.83 bar) of boost. It would have displaced 1,119 cu in (18.34 L). With its 14 ft (4.27 m) three-blade propeller turning, this early Typhoon IB warms up its Sabre engine for a flight. Given the Napier designation E101, the engine had a 5.0 in (127 mm) bore, a 4.75 in (121 mm) stroke, and a total displacement of 2,239 cu in (36.68 L). The Sabre VA powered the Tempest VI. Wilkinson took out a patent for the sleeve drive (GB363850, application dated 7 January 1931), and Vigers took out patents for sealing rings on a plug-type cylinder head (GB390610, application dated 15 February 1932) and sleeve-valves (GB408768, application dated 24 January 1933). Etsys 100% renewable electricity commitment includes the electricity used by the data centres that host Etsy.com, the Sell on Etsy app, and the Etsy app, as well as the electricity that powers Etsys global offices and employees working remotely from home in the US. maximum power (combat rating) at 3,850 R.P.M at 2,250 ft. altitude with moderate supercharge. I include this source as an example that I was not just blindingly including numbers. The following is a link to a YouTube video on Michell: His work on crankless engines starts just before 40minutes and the XB-4070 just after 47 minutes. I remember seeing an advertisement in Flight magazine (from the archive while it was still available) by Napier where they quote the Sabres power output as up to 3500HP, i do not think they specified what standard that power was measured to, normal, military, etc.. Production of the Sabre was an expensive affair, with each horsepower costing four to five times that of the Rolls-Royce Merlin. At each corner of this equilateral . The supply of Sabre engines fell behind the production of Typhoon aircraft, and engineless airframes sat useless at manufacturing facilities. To enable personalised advertising (like interest-based ads), we may share your data with our marketing and advertising partners using cookies and other technologies. This setup enabled the sleeves to operate at half crankshaft speed (and half the speed of the sleeve-valve drive shaft). Only around 24 of the Sabre-powered versions were built. Youve outdone yourself a very impressive essay made even better with astounding photographs, particularly of the engine during assembly. The coolant and fuel pumps were mounted below the engine, while the oil pumps were internal. This one was a long time coming. The Sabre III was selected for the Blackburn B-37 Firebrand carrier strike aircraft. The Coffman cartridge starter caused other issues; its sudden jolt when starting the engine occasionally damaged sleeve-drive components, setting up their inevitable failure. This is a Great Pattern that will provide Challenging Fun! flown hard by RAF Tempest units up to the mid `50s, The rear four exhaust ejectors were replaced with elongated stacks to prevent excessive heat build-up on the wings leading edge. for RAF jet-jockeys, (one remark made to a dubious Around November 1939, the Air Ministry ordered 500 examples of the Typhoon. A single half-sized, turbocharged Deltic power unit also featured in the English, Electric-built Type 2 locomotive, designated as the Class 23. Halford was disappointed that the Rapier and Dagger were not more successful. Today Napier is no longer in the engine business, with the ending of the Deltic sales in the 1960s they had no new modern designs to offer. In 1933, the British engineering firm D. Napier & Son (Napier) acquired licenses to produce the Junkers Jumo 204 and 205 aircraft engines. Len Setrights emotive/enthusiastic writing style Hello Rob No worries on the reply timeframe; I know how I goes. With a bore diameter greater than the stroke length, the Sabre was an over-square engine. Halford was contracted by the British engineering firm D. Napier & Son (Napier) in 1928 and built the Rapier I (E93) in 1929 and the Dagger I (E98) in 1933. Four aftercoolers were to be installedone on each induction runner leading from the supercharger housing to the intake manifold attached to the cylinder bank. Other aircraft suffered as well. Comes with its camshaft. Set where you live, what language you speak and the currency you use. engine became better known as the "Baby Deltic". The engine would then be removed, returned to the aircraft factory, and installed in another Typhoon to shuttle that aircraft away, repeating the process over and over. Stamped 17832 E445 also cast 09152 into right rear arm. Napier began work on a remarkable new engine, the Lion, in 1916. The aircraft continued to test annular radiators through 1948. (Napier/NPHT/IMechE image). ALL DOWNLOADABLE PRODUCTS ARE AVAILABLE INSTANTLY AFTER PAYMENT! Also in March, the engine passed a 50-hour test that included a peak output of 2,050 hp (1,529 kW). The upper and lower crankshafts also respectively drove upper and lower auxiliary drive shafts. Anyway, I hope the above was helpful. Halford was already involved in turbojet engine development at de Havilland before his departure from Napier, and some accused him of neglecting his duties on the Sabre. Individual ejector exhaust stacks were fitted, replacing the two-into-one stacks previously used on most Sabre engines. Birmingham MSI (VII) - presumably in store with all their other aero engines. The Sabre V was tested in the Tempest I, and the combination was first flown on 8 February 1944 by Bill Humble. The engine powered four English Electric traction motors that gave the locomotive 47,000 lbf (209.1 kN) of tractive effort. (He need only compare the boost-level/fuel grade Since mid-1938, a plan was underway to use an uprated Sabre engine in a specially-designed aircraft for a speed record attempt. Hawker Fury Prototype LA610 was fitted with a Napier Sabre VII to become the fastest piston-engined Hawker aircraft after reaching a speed of around 485 mph (780 km/h). Next is a row of pistons sitting inverted, each with rings and a piston pin. As far as I know, there are no complete engineering or production drawings for any mark of Napier Sabre, I have only seen a few drawings of the Sabre blocks of an early mark and the linkages of a late mark fuel system. The starter had a five-cartridge capacity. Through all this, Bulman continued to work with Napier, but the Ministry of Aircraft Production handed all responsibility for the Sabre engine to Banks in early 1943. The engine shortage was so severe that a good Sabre would be installed in a Typhoon to ferry the aircraft to a dispersal facility. the damned with faint praise end of the spectrum, I had a look around and can not find what I used as a basis for the 3500hp, it certainly was not the Nomad, either of them, nor any other Napier engine. Sleeve-valves were seen as a way to extract more power out of internal combustion engines. MTB safety would be improved if a switch to diesel engines could be made. While some of the ducted spinner research was applied to the Napier Naiad turboprop, none of the work was applied to production piston engines. Ultimately, the 539 cu in (8.83 L) Rapier VI (possibly E106) produced 395 hp (295 kW) at 4,000 rpm in 1936, and the 1,027 cu in (16.84 L) Dagger VIII (E110) produced 1,000 hp (746 kw) at 4,200 rpm in 1938. Tempest: Hawkers Outstanding Piston-Engined Fighter by Tony Buttler (2011) Given the Napier designation E101, the engine had a 5.0 in (127 mm) bore, a 4.75 in (121 mm) stroke, and a total displacement of 2,239 cu in (36.68 L). The design of these components was changed for the Sabre IV and later variants. Another fascinating article on what has to be one of the most interesting aircraft engines ever designed. Halfords 2,000 hp (1,491 kW) engine was given the Napier designation E107 and became known as the Sabre. However, two- and six-cylinder test engines had been built to test the sleeve-drive mechanism and prove the validity of the entire design. The Sabre II would ultimately replace the Sabre I in Typhoon IAs and IBs, and the Sabre I was phased out around October 1941. The worm wheels and their separate housings were mounted to the inner sides of the cylinder blocks. [7] The. to fly and fight fundamentals by reading your articles, This used the Michell tilting pad trust bearing to transmit the linear trust of the piston to the rotating slant. All of this equipment was mounted as compactly as possible to the top of the engine. Some of the technologies we use are necessary for critical functions like security and site integrity, account authentication, security and privacy preferences, internal site usage and maintenance data, and to make the site work correctly for browsing and transactions. I can think of no reason why Napier would falsely claim the figure, what purpose would it serve? Napier Deltic Engines Search There are currently no Napier Deltic Engines listed on Diesel Engine Trader Customer Testimonials 'We bought a new John Deere engine via DieselEngineTrader.com for a great price and were able to sell it locally for $1000 less than our competition. Sandwiched between the crankcase halves was an upper and lower crankshaft, each secured by seven main bearings. The Napier Sabres block-like exterior hid the engines complicated internals of 24-cylinders, two crankshafts, sleeve-valves, and numerous drives. Major Piston Aero Engines of World War II by Victor Bingham (2001) In early 1945, the Sabre VI with an annular radiator was test flown on a Tempest V (NV768). Blackburn Aircraft since 1909 by A. J. Jackson (1968/1989) Also note the supercharger torsion bar extending through the hollow sleeve-valve drive shaft. I believe the 3,655 is a mistake and it should read 3,055.. Ready to cut downloadable Patterns and Projects for your CNC Router, Milling Machine, Plasma Cutter or Laser Machine and Scroll Saw in both Imperial Inch format as well as Metric size for the Global CNC Hobbyist. The Air Ministry enabled the free flow of information between Napier, Halford, and Harry Ralph Ricardoa British engine expert who had been researching sleeve-valve engines for quite some time. Etsy is powered by 100% renewable electricity. At that time, Napier began work to produce additional Sabre engines for the Typhoon order, but production was still a very limited affair. (Napier/NPHT/IMechE image) Note that the fan rotates in the opposite direction from the propeller and that the lower cowling folds down level to be used as a work platform. do himself a service by learning about approved for The boost controllers were factory sealed, and severe repercussions were put in place for their unauthorized tampering. Aircraft Engines of the World 1946 by Paul H. Wilkinson (1946) Changes were made to the starter drive, and a priming mixture of 70 percent fuel and 30 percent oil was utilized to maintain an oil film in the cylinders. The Sabre VII ultimately produced 3,500 hp (2,610 kW) at 3,850 rpm with 20 psi (1.38 bar) of boost. I was trying to estimate the heat rejection of the engine if it was to produce that sort of power for any length of time, the mind boggles. Rather than being parallel, as in earlier Sabre engines, the electrode of the front spark plug was angled forward, and the electrode of the rear spark plug was angled back. In 1935, Halford joined Napiers Board of Directors, acting as the companys Technical Director. Carbon build-up was causing issues with the lubrication system. These Approximations are given in Imperial and Metric. You could potentially have a 72 cylinder engine placed in the middle of the chassis taking up around 16" in space running to a front and rear (multi-speed differential/transmissions) for awd (traction/management) in a 4 door sedan with and all of the power trains weight sitting lower to the ground then anything out except for electric. Fork-and-blade connecting rods were used, with the forked rods serving the three front-left and three rear-right cylinders of the upper banks and the three front-right and three rear-left cylinders of the lower banks. The radiator incorporated cooling elements for both engine coolant and oil. Sources: Initially, the Sabre VII had a takeoff rating of 3,000 hp (2,237 kW) at 3,850 rpm with water/methanol injection and 17.25 psi (1.19 bar) of boost. requirements at max BMEP outputs for the most Linkages were incorporated to allow one lever to control the engines throttle and the propellers pitch along with automatic boost and mixture control, but this system could be overridden by the pilot. At 3,500 rpm, the engine had a normal rating of 1,890 hp (1,409 kW) at 5,000 ft (1,524 m) and 1,630 hp (1,215 kW) at 16,500 ft (5,029 m). The crankshafts were phased at 180 degrees, and a cylinder for each crankshaft fired simultaneously. (Napier/NPHT/IMechE image). I dont recall seeing ads for a 3,500 hp Sabre. Change). On 12 February, an order for 700 Sabre V-powered Tempest Is was issued. Request for your free quote. NAPIER'S NEW TURBOPROP ENGINE NAPIER ELAND PUBLICITY HANDOUT AEROPLANE MAG 1954. The sleeves had a hardened belt on their inner diameter at the top of the piston stroke. In the spring of 1943, some 1,250 engines had accumulated a total of 12,000 hours of testing and 40,000 hours of service use, and the Sabres service life was extended from 25 hours to 250 hours between major inspections. The engines military rating at 3,850 rpm with 15 psi (1.0 bar) of boost was 2,600 hp (1,939 kW) at 2,500 ft (762 m) and 2,300 hp (1,715 kW) at 13,750 ft (4,191 m). By the end of 1966 Napier's Liverpool Works had manufactured its 500th Deltic. Napier produced a wide range of luxury automobiles in a variety of body styles until the early 1920s, when the company shifted into the aerospace engine segment. Montague Napier passed away on 22 January 1931, but Nowlan continued design work under the direction of George Shakespeare Wilkinson, Ronald Whitehair Vigers, and Ernest Chatterton. Starting around August 1943, Sabre IIA engines were incorporated into production Typhoon IB and Tempest V Series I aircraft. This Napier Nomad can be seen in Scotland's Museum of Flight ** There's a very good documentary on the Typhoon with lots of pilots talking about their experiences with the aircraft and engine. Total Number of Employees. The engine was 81.1 in (2.06 m) long, 40.0 in (1.02 m) wide, and 51.1 in (1.30 m) tall. projected power outputs from long stroke cylinders This engine is now the most long-lived engine produced by D Napier & Son Ltd. and only now being replaced by a modern design fitted in the RN Hunt Class MCMV. The forged aluminum pistons were rather short with a minimal skirt, which was required for the engines relatively short stroke, use of sleeve-valves, and narrow width. This aircraft had the larger radiator and wing root carburetor inlets of the Tempest VI, but it did not have the additional oil cooler in the wing. While what is in the archives is not complete, Kim puts it all together for a detailed look at the various engine programs. Napier and Hawker experimented with annular radiators using various Sabre IIB engines installed on a Typhoon IB (R8694) and a Tempest V (EJ518). Ive long been a fan of the Sabre and hope to be able to hear/see one in action when the project to restore a Typhoon to flying condition is successful (see https://hawkertyphoon.com/ for details). Sogefi develops and produces solutions of engine temperature management for the whole application range: from small petrol engines to large diesel engines. The Firebrand (DD804) was first flown on 27 February 1942. A balance beam was mounted to the front of the two upper and the two lower compound reduction gears. As the sleeve rotated back and descended, the cylinders two exhaust ports were uncovered to allow the gasses to escape between the upper and lower cylinder banks. (Napier/NPHT/IMechE image). The " Napier Lion ", the world's first broad arrow engine design, first saw use in 1918 as an advanced 24 litre 12-cylinder "Lion II" broad arrow engine of 450 bhp. However, Sabre engine production was allocated to the Typhoon, and the Firebrand was reengined with the Bristol Centaurus. A volute spring acted on each side of the beam to equally balance the tooth loading of the helical reduction gears on the propeller shaft. This aircraft would go on to record a speed of 483 mph (777 km/h) at 18,500 ft (5,639 m) and 422 mph (679 km/h) at sea level. Part Engines & parts Napier for sale. Thanks to a complete product portfolio and a full cooling system knowledge, Sogefi designs and provides the right solution for engine temperature management in line with CO2 emission . (Napier/NPHT/IMechE images). Vampires the runaround at low-level!). A drawing of a Sabre II, which was the main production variant. Napier engine-s (and parts) for Napier. The Hawker Typhoon and Tempest by Francis K. Mason (1988) Finally, service crews were misadjusting the boost controller, creating an over-boost situation that led to detonation in the cylinders and damaged engines. When you purchase a makeCNC pattern you are agreeing to our Copyright Terms. Hello Steve Glad you liked the article. Fuel consumption at cruise power was .46 lb/hp/hr (280 g/kW/h). Setright made some unrealistic claims and this just adds fuel to the fire of the naysayers Would it be possible for you to narrow down the sources you used for the performance figures of the Mk VII? The exhaust ports opened 65 degrees before bottom dead center and closed 40 degrees after top dead center. maintenance. Aircraft written off 10/12/30. To make matters worse, the Typhoon was experiencing its own issues with in-flight structural failures. Note the two engine mounts on the side of the crankcase and third mount on the accessory housing. 2 was dismantled from Wartsila W18V32. "Nasty Class". Xcellent Car Care And 3D Wheel Alignment Bansingari, Bengaluru 3849opposite Fire Station Bansingari, Bansingari, Bengaluru - 560085, Dist. Kimble McCutcheon has written an excellent book on the American sleeve valve engines. I do not hold out a great deal of hope that this was reached in any meaningful way. There are three fitted axially at the main bearing to web joints and Deltic 22 Twin Napier Action - back on 2 Engines - May 3rd 2010 - Duration: 0:59. traintelevision Recommended for you. The special engine produced 2,450 hp (1,827 kW) at 3,800 rpm with 9.2 psi (.63 bar) of boost and was first run on 6 December 1939. Our company has been successful in winning appreciation from the clients in Bike Engine Repair Services. Bristol became unhappy with sharing its components and processes with a competitor, and Napier was still hesitant to utilize Bristols materials and techniques. As he had done with the Rapier, Halford showed his design to George Purvis Bulman, the Deputy Director of Engine Research and Development for the British Air Ministry. The Super Pumper was used from 1965-1982 to supply large amounts of seawater when necessary for fighting fires. Otherwise, the aircraft was similar to the Tempest V. A Tempest V Series I (top) and Tempest VI (bottom). The first prototype (LA610) made its initial Sabre VII-powered flight on 3 April 1946. The Napier company decided first to develop a large 24 cylinder liquid-cooled engine, capable of producing at least 2,000 hp (1,491 kW) in late 1935. The engine had a takeoff rating of 2,065 hp (1,540 kW) at 3,850 rpm. Cooling the more powerful engine in warmer climates required modifications to be incorporated into the Tempest VI, including a larger chin radiator and a secondary oil cooler in the wing. The Tempest I was rather elegant without the large chin radiator, and the wing radiators were similar to those that would be used on the Sabre VII-powered Fury. The Tempest I was powered by the Sabre IV engine. At 4,000 rpm, the Sabre III had a takeoff rating of 2,250 hp (1,678 kW) and military ratings of 2,310 hp (1,723 kW) at 2,500 ft (762 m) with 9 psi (.62 bar) of boost and 1,920 hp (1,432 kW) at 16,000 ft (4,877 m). Opens in a new window or tab. It would have displaced 2,985 cu in (48.91 L). General arrangement drawing of the unbuilt Sabre VIII (E122). Revised gears turned the impeller at 4.68 times crankshaft speed in low gear and 5.83 times crankshaft speed in high gear. I hope that it can return someday. A glaring example being his seemingly blithe acceptance 1 prepared as spare parts.Rotor is completly new To see the contact details please Login or Register Bulman was back in Engine Research and Development and continued to work with Halford and Napier to resolve issues with the Sabre. What an engine and lets hope someone gets one running. I have to admit that I can find no evidence for my recollection of the up to 3500hp power rating and must conclude hat I must have been dreaming, most likely I have conflated two different things this, of course, is how these questionable claims start. Twelve exhaust ports were located in a single line on each side of the engine, and each ejector exhaust stack served two portsone for an upper cylinder and one for a lower cylinder. It would seem that many of these Sabre-related When ports in the sleeve-valve aligned with three intake ports cast into the cylinder, the air and fuel mixture was admitted into the cylinder. Buy an engine for a NAPIER machine, at the best price and best delays. That number was also in the book on Frank Halford, Boxkite to Jet, not a primary source so not really useful to this discussion. On completion the assemblies spin freely in the fixture all ball bearing assembly to be designed. Janes All the Worlds Aircraft 1945/46 by Leonard Bridgman (1946) Last in use in 1931. British Institution of Mechanical Engineers. The Sabre VII carried the Napier designation E121 and was essentially a VA engine strengthened to endure higher outputs. The saddest part of all this is just how little documentation for these British engines has survived. Aircraft Engines of the World 1945 by Paul H. Wilkinson (1945) Aircraft Engines Volume Two by A. W. Judge (1947) on page 477 states: Series VII 3,655 h.p. Each sleeve-valve drive shaft was driven at crankshaft speed through a layshaft by an upper compound reduction gear. The BAPC listing, compiled by Peter Kirk in 2003, also has the following: 1064 (Honiton) ATC. In the foreground are the individual cylinder heads with their sealing rings. Sabre development at Napiers works in Acton, England progressed quickly, and single-, twin-, and six-cylinder test engines were all running by the end of 1936. Further right are six sleeve-valve cranks, followed by their housings, and a set of 12 sleeves. Via a fluid-actuated clutch, the two-speed supercharger was driven at 4.48 times crankshaft speed in low gear (often called moderate supercharging, MS) and 6.62 times crankshaft speed in high gear (often called full supercharging, FS). Hitherto, in the Royal Navy, such boats had been driven by petrol engines, but their highly, flammable fuel made them vulnerable to fire, unlike the opposing diesel-powered, While the Deltic engine was successful in marine and rail use and very powerful, for its size and weight, it was a highly strung unit, requiring careful. The 3,055 hp (or 3,050 hp) figure is pretty widely reported, so I will skip that one. At the center of the radiator is the open carburetor intake, which was later covered by a momentum air filter. documents are now kept in the archives of the Please Click on the Link Below to View them! The engine featured a two-stage supercharger and contra-rotating propellers. Learn how your comment data is processed. In many ways it confirmed my suspicions. After the initial production difficulties, which were quite severe, the engine served with distinction. I am sorry it took me almost a year to reply to you. The prototype Tempest I (HM599) was first flown on 24 February 1943, piloted by Lucas, and would go on to record a speed of 472 mph (760 km/h) at 18,000 ft (5,486 m) in September 1943. In 2016 I was at Burlen Fuel Systems in Salisbury and had a brief look at the SU carburetor used on the early versions of the Sabre. This was still about 75 mph (121 km/h) faster than the aircrafts original design speed. The Sabre VA had a one-sided supercharger impeller, a relocated supercharger clutch, and a two-barrel injection carburetor. The sleeve was nitrided to increase its hardness and was not more than .0002 in (.005 mm) out of round. The Sabre VI was the same engine as the Sabre VA, but it incorporated an annular nose radiator and provisions for a cooling fan, all packaged in a tight-fitting cowling. The cylinder head acted as a plug atop the cylinder and was sealed against the sleeve by a compression ring. The prototype Tempest VI (HM595 again) made its first flight on 9 May 1944, piloted by Humble. In July 1939, the Air Ministry ordered 100 production engines and material for another 100 engines. The spark-ignition engine had a similar layout to the E101 dieselboth being liquid-cooled H-24s with sleeve-valves and possessing the same bore and stroke. The upper and lower cylinders were numbered 112, starting from the left rear and proceeding clockwise to the right rear. was rightly critiqued, but he did claim to have A Sabre VII with its revised supercharger housing that accommodated water/methanol injection. Aircraft Engines Volume Two by A. W. Judge (1947) In 1984 I stood next to the Sabre engine on display at the RAF Museum Hendon ( now London I think ) for some time, amazed at the complexity of it. With Sabre reliability issues resolved and production resuming, development of the engine continued. jet pilot was: Make no mistake, without the target The rotational movement of the sleeve crank caused the sleeve to reciprocate and oscillate in the cylinder bore. There were a number of engineers there who had worked on the Saber production. Note the underwing identification/invasion stripes. Each sleeve had only four ports, one of which was used for both intake and exhaust. The engine was selected for the Tempest I, the prototype of which was initially ordered on 18 November 1941, followed by an order for 400 production aircraft in August 1942. The Napier Deltic engine is a British opposed-piston valveless, supercharged uniflow scavenged, two-stroke diesel engine used in marine and locomotive applications, designed and produced by D.
