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 7,000 kgf (15,000 lbf; 69,000 N). 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:[1]

  • Maximum thrust at take-off = 20,000 kgf (44,000 lbf; 200,000 N)
  • Maximum thrust during supersonic cruise = 5,000 kgf (11,000 lbf; 49,000 N) altitude = 18,000 m (59,000 ft), speed = 2,350 km/h (1,460 mph)
  • Maximum thrust during subsonic cruise= 3,000 kgf (6,600 lbf; 29,000 N) altitude = 11,000 m (36,000 ft), speed = 1,000 km/h (620 mph)
  • Temperature = 1,355 K (1,082 °C; 1,979 °F)
  • Diameter = 1,486 mm (58.5 in)
  • Length = 5,976 mm (235.3 in)
  • Mass = 3,900 kg (8,600 lb)

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 26,000 m (85,000 ft) at low flight speed (M = 0.6).

  • P = 7,000 kgf (15,000 lbf; 69,000 N)
  • 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 (35,600 lbf; 158,400 N)

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] It is recognizable by the translating-plug variable-area nozzle.[4]
RD-36-51A
The RD-36-51A produced 20,000 kgf (44,000 lbf; 200,000 N) 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.
