  Junkers Jumo 205 - Wikipedia, the free encyclopedia
The Junkers Jumo 205 aircraft engine was the most famous of a series of diesel engines that were the first, and for more than half a century, the only successful diesel aircraft engines.
The Jumo 205 powered the early versions of the Junkers Ju 86 bomber, but was found too unresponsive for combat and liable to failure when used at maximum power as is common for combat aircraft.
The Jumo 203 and 204 were licensed to Napier and Son, who built a small number as the Napier Culverin just prior to the war.

 Junkers Engines - Fo4 / Jumo 4 / Jumo 204
The first flight with a Junkers Diesel Oil engine was performed on 30th August 1929 with a Junkers F24 (c/n 832) enroute from Dessau to Cologne.
As problems were rising during the type certification of the Jumo 4, which also reduced the maximum power, available from this engine, further trials and improvements were made on the engine after certification.
Compared to the Jumo 4, the pistons of the Jumo 204 got crowns of heat resistent steel It offered more power on same turn rates and was higher pressured.

 Junkers G.38
The Junkers G.38 was a large German 4 engined transport airplane of the 1930s.
It had four 750 hp (560 kW) Jumo 204 engines and was unique in that some of the passengers were seated in the wings.
It carried a total of thirty four passengers, six in two compartments in the leading edge of the wing and the rest in the main fuselage.

This ratio was decreased to 1.52 on the Jumo 205 of 16.6 liters, and to 1.23 on the Jumo 206 (25.5 liters by a bore increased to 130 mm) intended to replace the Jumo 204, obsolete by 1937.
The Jumo 224 project made use of cylinder dimensions identical to those of the Jumo 207 D, that is to say 110·(2·160) for a displacement of 73 liters, and a power of some 4500 hp at 3000 rpm.
Contrary to the case of engines such as the Jumo 223 and 224 which were laid out in a square (or rhombus), the triangular construction of the Deltic meant it was necessary to mount an intake piston/ con-rod assembly and an exhaust one on the same crank pin.

 Junkers Engines - Jumo 206
The Jumo 206 was intended as a replacement of the Jumo 204 and was based on the Jumo 205.
The bore/stroke ratio of the 206 was reduced by 20% and at the same time, the volume was increased by 30% against the Jumo 205.
Several prototypes were built between 1937 and 1940, but finally the Jumo 206 design was stopped in 1940 it was continued under a new concept as Jumo 208.

Curtiss Wright was designing an engine of this sort of power known as the "turbo-compound", but Sir Harry Ricardo, one of Britain's great engine designers, suggested that the most economical combination would be a similar design using a diesel two-stroke in place of the Curtiss's gasoline engine.
Prior to World War II Napier had licensed the Junkers Jumo 204 Diesel design to set up production in the UK as the Napier Culverin, however the start of the war made the Sabre all-important and work on the Culverin was stopped.
In response to the Air Ministry requirements they dusted off this work, combining two enlarged Culverin's into an H-block similar to the Sabre, resulting in a massive 75 litre design.

The engine was the Jumo 204, rated at 520 HP at first, the aircraft was a Junkers F.24.
I'm not sure who was the first internationally, but Junkers was the first at least in Germany to put a Diesel engine on an aircraft.

The Bristol 171 was built in various civil and military configurations, such as transport, search-and-rescue and ambulance, and was a four or five-seat helicopter powered by an Alvis Leonides Mk 173 nine-cylinder radial air-cooled engine providing a top speed of 204 kmh and a range of 430 km.
The Bristol 192 is a British tandem-rotor helicopter that was designed in response for a British military requirement for a large helicopter capable of troop and freight transport, paratrooping, supply-dropping, ambulance duties and also sear-and-rescue operations.
The Blohm and Voss Bv 222 was a high wing cantilever monoplane powered by six BMW Bramo 323 R 9-cylinder radial or Junkers Jumo 207 C 12-cylinder opposed compression-ignition engines inline in the leading edges of the wings providing a top speed of 336 kmh.

Another version was to add two Jumo 004 jet engines outboard of the four radial BMW engines, and was submitted to the Luftwaffe for evaluation.
A variety of engines were considered for the Me 264, including a four Jumo 004C jet engined version, a two or four BMW 028 turboprop engined version and a twin BMW 018 turbojet powered version.
Again, the Jumo 222 E/F would have been the most efficient engines for high altitude operations, and it was planned to re-equip this aircraft when these engines became available.

Up to this point, diesel engines were characterised by their poor power-to-weight ratio and their slow speed.
However Napier had been working on various aviation diesel designs, licensed versions of the Junkers Jumo 204, prior to the start of the war.
The Admiralty felt these would be a reasonable starting point for the larger design they required.

**The Yakovlev Yak-15/17 Feather was an adaptation of a standard Yak-3 airframe made to accommodate a Junkers Jumo 004A turbojet captured by the Russians during their advance into Germany.
Deliveries to Soviet Air Force fighter squadrons began early in 1947, produjction aircraft retaining atailwheel undercarriage and being powered by the RD-10 engine as the Jumo 004B copy was known.
At he time of its introduction the Yak-15 was the lightest jet fighter in the world,the lightweight structure of the Yak-3's airframe compensating for the relatively low power of the RD-10 engine.

Also interesting is that the first 109, the Bf-109V1, flew for the first time in September 1935 powered by a British Rolls-Royce Kestrel of 695 hp, since the Junkers Jumo 210 was not available then.
After a crash it was rebuilt and had the Jumo engine installed.
The RLM was not at all involved and in fact didn’t even know about it until after its first flight.
