Kolesov RD-36

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

Design and development
Developed at OKB-36 (P. A. Kolesov) and produced at the Rybinsk Motor-Building Plant. The RD-36-51A engine was developed for the Tu-144D supersonic passenger aircraft. A simplified modification with a fixed nozzle for the high-altitude Myasishchev M-17 was designated RD-36-51B. The engine develops a thrust of 7000 kgf. The RD36-51A engine passed all state bench and flight tests in 1973–75 (with flight testing on the Tu-144D). The engine's specifications were: For the high-altitude M-17 "Stratosphera" aircraft (NATO reporting name Mystic-A) 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 26000 m at low flight speed (M = 0.6). RD-36-51A / B are released in a small series (about 50 pieces).
 * Maximum thrust at take-off = 20000 kgf
 * Maximum thrust during supersonic cruise = 5000 kgf altitude = 18000 m, speed = 2350 kph
 * Maximum thrust during subsonic cruise= 3000 kgf altitude = 11000 m, speed = 1000 kph
 * Temperature = 1355 K
 * Diameter = 1486 mm
 * Length = 5976 mm
 * Mass = 3900 kg
 * P = 7000 kgf
 * With beats. vsl. = 0,88 kg / kgf • h.

Variants
Thrust – 16150 kgf
 * RD-36-41:Created on the basis of the engine  'VD-19' .
 * 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. It is recognizable by the translating-plug variable-area nozzle.
 * RD-36-51A:The RD-36-51A produced 20000 kgf thrust at take-off and had a cruise thrust-specific fuel consumption of 1.22 kg/(kgf. h). 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

 * Tupolev Tu-148 (RD-36-41)
 * Sukhoi T-4 (RD-36-41)
 * Tupolev Tu-144D (RD-36-51A)
 * Myasishchev M-17 Stratosphera (RD-36-51B)
