FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering, particularly, to helicopters. Aircraft (1) is capable of hovering, has drive means (7) and at least one exhaust duct (8, 8') connected to an outlet of drive means (7) to expel exhaust gas, produced by fuel combustion, from aircraft. At least part of exhaust duct (8, 8') has a thermoelectric conversion circuit (15) for Seebeck-effect converting to electric energy thermal gradient produced between inside and outside of the exhaust duct (8, 8') by flow of exhaust gas.
EFFECT: longer flight range, reduced fuel consumption, improved speed characteristics.
