NK-32
The Kuznetsov NK-32 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-144LL 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 General Electric GE90. Such engines sacrifice exhaust speed for higher thrust and hence cannot accelerate to supersonic speeds).
It produces 55,000 lbf (245 kN) of thrust in maximum afterburner.
- Cruise thrust: 14 000 kgf (31,000 lbf, 137 kN)[1]
- Afterburning thrust: 25 000 kgf (55,000 lbf, 245 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: 6,000 mm (20 ft)[3]
- Diameter: 1,460 mm (4.79 ft)[3]
- Dry mass: 3,400 kg (7,500 lb)[3]
