Czechoslovakia Malesice M-04    A copy of the German Junkers Jumo 004, assembled at the repair works in Malesice using new and spare parts. Used to power the Avia S 92 / CS 92.   France Lorin Ramjet Invented in 1908 by French man René Lorin, it consisted of just a tube, at one end air enters by the forward motion of the plane, it is compressed by the inlet, then fuel is added and burnt, all the energy being in the exhaust, which is expelled at the other end. Some what be for it's time, as the ramjet does not start to work until around 200 mph, but it gets more efficient the faster it goes! Experimented with by Germany, Russia and the USA. Fitted under the wings of there piston engined fighters to increase speed , but was found impractical because of high fuel consumption and high drag. But it was used very successfully by Doblhof on the worlds first jet powered helicopter in 1944, the WNF V-4. which had ramjets at the tips of it's blades. (see also USSR). In France however René Leduc continued Lorin's work from 1937, seeing his own Lorin powered aircraft the Leduc 010 flying under it's own power in 1947.     A drawing of the Lorin engine of 1909

Jendrassik

Cs-1   

Designed by Gyorgy Jendrassik in 1938 the Cs-1 was the worlds first working turboprop engine, first run in 1940 and hoped to produce 1,000 hp it never made more that 400 hp due to combustion problems. All work on the engine was stopped in 1941 as the Daimler-Benz DB 605 engine was to be made in Hungary. A plane was specifically made for the Cs-1 the RMI-1 X/H, which ironically was fitted with the DB 605 in 1944.

Campini

Invented by J.S.Harris in 1917. The Campini "Thermojet"engine was designed by Ing Secondo Campini in 1931. The engine consisted of a 900 hp Isotta Fraschini L.121/R.C.40 piston engine driving a compressor which used two ducted fans to compress the air and one fan to direct the flow of air, a ring of injectors introduced fuel and the air/fuel mix was burnt to give thrust. Used on the CC.2-N1

Ka-10  (pulsejet)    A license copy of the Argus As 014.

Tsu-11    A Campini-type motor jet, Powered by a convention Hitachi 4 cy engine, producing 551 lb of thrust. Used in the Ohka 22.

Ne-20    A copy of BMW's 003 made in 1944/45 making around 800kg of thrust. Used in the Kikka, Ki 201 and Ohka 43.

   

Ne-130/230 Under development at the end of the Second World War, never completed.

Coanda

The Air-Reactive Engine    The worlds first jet engine designed and made by Henri Coanda in 1910, the engine worked with a piston engine driving a compressor which fed air to "Burning Rooms" were the exhaust from the piston engine and fuel was mixed along with the compressed air, the exhaust of which produced thrust.
