FIELD: transport.SUBSTANCE: invention relates to aircraft engineering, particularly, to aircraft engine control systems. Proposed poser plant comprises engine frame, engine engaged via transmission with propulsor and propulsor turn drive. Transmission consists of the shaft arranged in the beam to engage the engine with propulsor reduction gear input shaft. All power plant components are arranged at integral engine frame. Said beam can turn about transmission shaft axis. Note here that beam part blown in cross-section features symmetric streamlined profile while its cross-section is always directed along screw airflow at whatever turn angle. Power plant can comprise two engines each being engaged via its transmission with common shaft and can be equipped with second propulsor arranged at the right of left of the engine. Note here that every propulsor is connected with its reduction gear by turn beam. Said propulsors can be composed of coaxial screws connected by T-shape reduction gearbox with shaft arranged in turn beam.EFFECT: lower drag, higher safety of engine fault, drive higher power and lower weight.7 cl, 7 dwg |
