    VRD-430 (ramjet)   

    A ramjet of 400mm diameter, tested from late 1940 onwards.


    VDRK (Air-reaction engine compressor)   A small motorjet engine using a geared drive from the aircraft's piston engine to drive it's compressor, with air being fed from the aircraft's radiators, making around 600 lb of thrust. Developed from 1942 by a team led by K.V.Khholshchyevnikov. Used in the combination powered Mig-13 and Su-5.


    A.M.Lyul'ka should be known as the farther of the Soviet Jet engine, as in 1938, wile he was working at the Kharkov Aviation Institute in a team developing the engine and compressor for the Tupolev Pe-8 heavy bomber, he designed a two stage centrifuge turbojet engine (the RDT-1) with an estimated out put of around 500 kg (1,100 lb) of thrust. On the 12/7/1940 the defence committee of the Soviet Government, stressed the necessity of continuing the work on the Lyul'ka engine, with the aim of testing the engine parts by December 1940!
    Development of the engine (now named the RTD-1/VDR-2) continued and by 1943 parts of the engine such as the combustion chamber and a two stage axial compressor had been tested very successfully. By this stage a full prototype engine had being made "to 70% readiness", work on the RTD-1 stopped in 1943 as Lyul'ka then began work on a larger engine which it was hoped would produce 1,500 kg of thrust, the S-18.
    The USSR's first turbojet a two stage centrifuge engine, making an estimated 700 kg of thrust, tested in 1943. It was intended to fit the engine in the Gu-VRD fighter, but the project was canceled in mid 1943.
    S-18/VDR-3   The 2nd Lyul'ka turbojet to run, a axial flow engine, making around 1,250 kg of thrust, tested in Aug 1945.
    A eight stage axial flow engine developed from the S-18,making 1,300 kg of thrust, cleared for use in December 1946. The first Lyul'ka engine to fly, Fitted to the Alekseyev I-211, Tu-22, Su-11 and Su-10


DM - Dopolnityelnyi Motor (supplementary motor) A series of booster engines designed by I.A.Merkulov from 1939.

    DM-1 (ramjet)    A 200mm diameter ramjet, operating on the same fuel as a piston engine, tested in 1939.
    DM-2 (ramjet)    Based on the DM-1 A larger ramjet, with a 400mm diameter, first tested in Jan 1940
    DM-4 (ramjet)   
    A larger ramjet of 500mm diameter and weighting 30 kg. The engine required ethyl alcohol to be added to the existing fuel, tested from Oct 1940.
    DM-4C(ramjet)   An improved version of the DM-4, first tested in 1942 fitted on to a Yak-UTI and again in 1944 on a Yak-7B, also fitted to the Yak-7R.


    A copy of the German Junkers Jumo 004 engine, developed further at Kazan as the RD-10 with 910 kg of thrust, 10A 1,000 kg of thrust and 10F with 1,100 kg of thrust. Fitted to the La-150/152/154/156, Su-9 and Yak-15/18/21
    RD-20 (RD-21)   The German BMW 003 axial flow engine, developed at GAZ-17 with a thrust of 800 kg, RD-20F later designated as the RD-21 with 1,000 kg of thrust. Fitted to the Mig I-300 and Mig I-301T
Maker unknown
    RD-13/D-10 (pulesjet)   
    A Pulsejet engine making around 400 kg of thrust. Developed from the German Argus As 014 / 044 pulsejet program.
