Not to be confused with the un-related Rybinsk RD-36-35 lift engine.

The Kolesov RD-36 was a supersonic turbojet engine used on various Soviet aircraft projects.

Design and development

Developed in OKB-36 P. A. Kolesov. The engine was produced at Rybinsk Motor-Building Plant. The RD-36-51A engine version was developed for a passenger supersonic aircraft Tu-144D. A simplified modification with a fixed nozzle for a high-altitude Myasishchev M-17 was designated as RD-36-51B. The engine develops a thrust of 68.6 kN (7000 kgf). The RD36-51A engine passed all state bench and flight (on the Tu-144D aircraft) tests in 1973-75. The engine had following parameters:^[1]

Maximum thrust at take-off = 20,000 kgf
Maximum thrust during supersonic cruise = 5000 kgf (altitude = 18000 m, speed = 2350 km / h)
Maximum thrust during subsonic cruise= 3000 kgf (altitude = 11000 m, speed = 1000 km / h)
Temperature = 1355 K
Diameter = 1486 mm
Length = 5976 mm
Mass = 3900 kg

For the high-altitude aircraft M-17 "Stratosphere" a single-shaft TRD RD36-51B was created - a modification of the RD36-51A engine with an unregulated nozzle and oxygen supply to the combustion chamber. The engine provides long-term operation at an altitude of 26,000 m at low flight speed (M = 0.6).

P = 7000 kgf
With beats. vsl. = 0,88 kg / kgf • h.

RD-36-51A / B are released in a small series (about 50 pieces).

Variants

RD-36-41: Created on the basis of the engine 'VD-19' ^[2].

Thrust - 16 150 kgf

RD-36-51: This engine was a replacement for the Kuznetsov NK-144 turbofan used on the Tu-144D SST, giving an increase in full payload range from 3,080km to 5,330km.^[3]. recognisable by the translating-plug variable-area nozzle.^[4]
RD-36-51A: The RD-36-51A produced 20,000 kgf thrust at take-off and had a cruise thrust-specific fuel consumption of 1.22 kg/(kgf. h).^[3] which gave the aircraft a maximum range of 6,500 km.
RD-36-51B: Non-afterburning turbojet for use in high-altitude reconnaissance/research aircraft, such as the Myasishchev M-17 Stratosphera.

Applications
