The invention provides an energy-saving propulsion system for a wing body fusion aircraft. The energy-saving propulsion system comprises a main engine, a thermoelectric conversion device, an electricenergy storage device, two sets of external fans and a motor for driving the external fans to rotate. On the basis of not changing the overall aerodynamic layout of the wing-body fusion aircraft, a certain number of external fans are arranged on the two wings of the aircraft to improve the equivalent duct ratio of the propulsion system, and thus fuel consumption and emission can be reduced; a plurality of thermoelectric conversion modules are arranged along the wall surface of a tail injection section of the main engine to absorb exhaust waste heat, and the exhaust waste heat is stored in theelectric energy storage device after being processed by thermoelectric conditioning modules; the stored electric energy can provide all or part of electric power can be provided for motors and aircraft power generation accessory equipment of the of an external fans after being stabilized, so that part of exhaust waste heat of the engine is recycled and converted into the electric energy for use, and power extraction and fuel consumption of the main engine for an aircraft power generation accessory system and the external fan equipment are reduced.
本公开提供了一种用于翼身融合体飞机的节能型推进系统,包括:主发动机、热电转换装置、电力储能装置、两组外置风扇、以及驱动所述外置风扇转动的电动机;本公开在不改变翼身融合体飞机整体气动布局的基础上,通过在飞机两翼设置一定数量的外置风扇来提高推进系统等效涵道比,从而可以降低燃油消耗和减少排放;通过沿主发动机尾喷段壁面布置若干热电转换模块吸收排气余热并通过热电调理模块处理后存储到电力储能装置中,存储的电能稳压后可以分别为外置风扇的电动机、飞发附件设备提供全部或者部分电力,从而将发动机部分排气余热回收转换为电能使用,降低主发动机用于飞发附件系统以及外置风扇设备的功率提取以及燃油消耗。
