Abstract

The invention is applicable to the technical field of aircrafts. The invention provides a distributed propulsion flying wing aircraft. The flying wing comprises a flying wing body and a distributed propelling system, the distributed propulsion system is arranged in the flying wing body and comprises a ducted fan system, a turbine engine system and a shaft power transmission system, and the shaft power transmission system transmits shaft power output by the turbine engine system to the ducted fan system. The distributed propelling system integrates a ducted fan system and a turbine engine system, the effect of a large-bypass-ratio engine is achieved, and the oil consumption rate of the flying-wing aircraft can be reduced by 25% or above.

Description

technical field [0001] The invention belongs to the technical field of aircraft, in particular to a distributed propulsion flying wing aircraft. Background technique [0002] Flying wing aircraft has both good aerodynamic performance and stealth performance, and has a long history of development. There are not many existing technologies related to flying wing aircraft. Among them, the patent US8191820B1 authorized in 2012 discloses a flying wing aircraft, which is characterized in that it includes flying wings, canards, and a high-pressure air distribution system. This patent mainly solves the problem of taking off Insufficient lift, pitch control and other technical problems. However, the flying-wing aircraft in this patent uses a conventional turbofan engine, and the fuel consumption index has not been significantly improved. It can only rely on a large fuel load to achieve long-distance and long-term flight, and the infrared stealth performance has not been significantly...
