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 version with a fixed nozzle for the high-altitude Myasishchev M-17 was designated RD-36-51B. The engine developed a thrust of {{convert|7000|kgf|lbf N|abbr=on}}.

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:{{cite book | isbn=978-0-7643-4894-5 | title=Tupolev Tu-144: The Soviet Supersonic Airliner | last1=Gordon | first1=E. | last2=Gordon | first2=Yefim | last3=Komissarov | first3=Dmitriy | last4=Rigmant | first4=Vladimir | date=2015 | publisher=Schiffer Publishing, Limited }}

  • Maximum thrust at take-off = {{convert|20000|kgf|lbf N|abbr=on}}
  • Maximum thrust during supersonic cruise = {{convert|5000|kgf|lbf N|abbr=on}} altitude = {{convert|18000|m|ft|abbr=on}}, speed = {{convert|2350|kph|mph|abbr=on}}
  • Maximum thrust during subsonic cruise= {{convert|3000|kgf|lbf N|abbr=on}} altitude = {{convert|11000|m|ft|abbr=on}}, speed = {{convert|1000|kph|mph|abbr=on}}
  • Temperature = {{convert|1355|K|C F|abbr=on}}
  • Diameter = {{convert|1486|mm|in|abbr=on}}
  • Length = {{convert|5976|mm|in|abbr=on}}
  • Weight = {{convert|3900|kg|lb|abbr=on}}

For the high-altitude M-17 "Stratosphera" aircraft (NATO reporting name Mystic-A) a single-shaft TRD RD36-51B was created. This was a modified version of the RD36-51A engine with an unregulated nozzle and oxygen supply to the combustion chamber. The engine provided long-duration operation at an altitude of {{convert|26000|m|ft|abbr=on}} at low flight speed (M = 0.6).

  • P = {{convert|7000|kgf|lbf N|abbr=on}}
  • With beats. vsl. = 0,88 kg / kgf • h.

RD-36-51A / B was produced in a small series (about 50 units).

Variants

;RD-36-41:Created on the basis of the engine 'VD-19' . "Aviation and Cosmonautics" No. 9–10 / 2001 // V. Rigmant "Long-range supersonic anti-aircraft fighters Tupolev interceptors "

Thrust – {{convert|16150|kgf|lbf N|abbr=on}}

;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 {{convert|20000|kgf|lbf N|abbr=on}} thrust at take-off and had a cruise thrust-specific fuel consumption of 1.22 kg/(kgf. h).Tupolev Tu-144, Gordon, Komissarov and Rigmant 2015,Schiffer Publishing Ltd., {{ISBN|978-0-7643-4894-5}}, p.248 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.
