FIELD: engines and pumps. ^ SUBSTANCE: proposed engine comprises gas generator with compressor and rear prop fan coupled with power turbine 8 via reduction gear 13 surrounded by acicular air and gas chambers. Radial and axial deflectors 21, 22 are arranged in air chambers 19 of posts 16 and air chamber 20 of housing 15 to make oil chamber 23 of reduction gear 13. Ring reflector 30 is arranged on housing ahead of rear support housing flange joint 24 with deflector 22 and reduction gear housing 25. Said ring deflector 30 makes annular slot-like cavity 31 with its outlet communicated with compressor. Ring deflector outlet is provided with nozzle 32 to blow flange joint 24. ^ EFFECT: higher engine reliability due to minimised heat flows onto reduction gear components. ^ 3 dwg |
