The invention provides a wing-body fusion body aircraft propulsion system. The wing-body fusion body aircraft propulsion system comprises a main engine, a fuel gas transition section, a fuel gas circulation device and N external fans. The main engine is connected with all the external fans through the fuel gas transition section and the fuel gas circulation device in sequence and drives the external fans to work. A configuration mode of a plurality of traditional gas turbine engines is changed by adopting a structural form of one main engine and the plurality of external fans. Compare to conventional engines, the structural form of the propelling system well solves a problem of limitation of the structure and the weight of a fan part of a single engine; meanwhile, air inlet interference resistance caused by a large air inlet section of a nacelle of a conventional engine is reduced; wind resistance is decreased, and aerodynamic characteristics are improved so that requirements of an aircraft on the fan with an ultrahigh equivalent bypass ratio can be better met; and the equivalent bypass ratio and propulsion efficiency of a propulsion system are improved, fuel consumption is reduced, and energy conservation and emission reduction requirements of a wing-body fusion body aircraft are met.
本公开提供了一种翼身融合体飞机推进系统,包括:主发动机、燃气过渡段、燃气流通装置,以及N个外置风扇;所述主发动机依次通过燃气过渡段和燃气流通装置与全部所述外置风扇相连,并驱动所述外置风扇工作。本公开通过采用一台主发动机和多台外置风扇的结构形式改变了传统的多台燃气涡轮发动机配置方式。与常规发动机相比,这种推进系统结构形式很好的解决了单台发动机风扇部件的结构以及重量的限制问题,同时减少了常规发动机短舱进气截面大带来的进气干扰阻力,降低风阻和提高气动特性,从而可以更好的满足飞机对于超高等效涵道比风扇的需求,提高推进系统的等效涵道比和推进效率,降低燃油消耗,满足翼身融合体飞机的节能减排需求。
