Abstract

The present invention is applicable to the field of aircraft technology, and provides a distributed propulsion flying wing aircraft, comprising a flying wing body and a distributed propulsion system, the distributed propulsion system is arranged inside the flying wing body, and the distributed propulsion The system includes a ducted fan system, a turbine engine system, and a shaft power transfer system, and the shaft power transfer system transfers shaft power output by the turbine engine system to the ducted fan system. The distributed propulsion system in the invention integrates the ducted fan system and the turbine engine system, which achieves the effect of a large bypass ratio engine and reduces the fuel consumption rate of the flying-wing aircraft by more than 25%.

Description

Technical field [0001] The present invention belongs to the field of aircraft, and in particular, the present invention relates to a distributed propulsion flying aircraft. Background technique [0002] Flying Wing Aircraft takes into account good aerodynamic performance and stealth performance, which has a long history of development. There are not many existing technologies involving the flying wing aircraft. In 2012, it is disclosed in the 2012 US8191820B1, which is characterized in that the flying wing, a duck wing, a high pressure air distribution system, which mainly solves the takeoff Insufficient strength, pitch manipulation control, and other technical issues. However, the flying wing aircraft in this patent uses a routine turbofan engine, and the fuel consumption rate indicator is not significantly improved. It can only rely on large carrier oil to achieve voyage, long-distance flight, and infrared stealth performance is not significantly improved. . Therefore, the flyi...
