Kuznetsov NK-32
From Wikipedia, the free encyclopedia
The Kuznetsov NK-321 is a military specification afterburning 3-spool low bypass turbofan jet engine which powers the Tupolev Tu-160 supersonic bomber, and was fitted to the later model Tupolev Tu-144 supersonic transport. It is the largest and most powerful engine ever fitted on a combat aircraft (however, higher thrust engines are fitted to civil aircraft such as Rolls-Royce Trent).
It produces 55,000 lbf (245 kN) of thrust in maximum afterburner.
- Thrust on the afterburner:25 000 kg (55,000 lb, 245 kN) [1]
- Thrust at cruising: 14 000 kg (31,000 lb, 137 kN)[1]
- Specific fuel consumption: (supersonic) 1.70 kg/kgf/hour[2]
- Specific fuel consumption (subsonic): 0.72-0.73 kg/kgf/hour[2]
- Bypass ratio: 1.4[3]
- OPR: 28.4[3]
- Length: 6000 mm[3]
- Diameter: 1460 mm[3]
- Dry mass: 3400 kg[3]
