Abstract

The invention discloses an efficient leading edge distributed propeller aircraft power layout, and particularly relates to the technical field of aircrafts. The efficient leading edge distributed propeller aircraft power layout comprises a plurality of electric propellers distributed on fixed wings on the two sides of an aircraft, the multiple electric propellers are symmetrically arranged in front of the fixed wings, and each electric propeller is provided with a nacelle connected with the corresponding fixed wing, the electric propellers at the wing tips of the fixed wings are located rightin front of the front edge points of the fixed wings, and the centers of the other propellers are all located above the front edge points of the fixed wings. By the adoption of the technical scheme, the problem that all distributed propellers of an existing aircraft are distributed right in front of the leading edge points of the wings, and consequently the aerodynamic performance of the aircraftis affected is solved, and the layout can be used for aircraft design.

Description

technical field

[0001] The invention relates to the technical field of aircraft, in particular to a power layout of an efficient leading-edge distributed propeller aircraft. Background technique

[0002] At present, distributed propulsion and electric propulsion technology are more and more widely used in the aviation field, and the distributed propeller propulsion technology applied to small and medium-sized aircraft has become a new hotspot in aviation research. The fundamental reason is that The distributed propulsion electric propeller has high propulsion efficiency at low speeds, can make full use of the slipstream lift to greatly improve the aerodynamic performance of the aircraft, meet the needs of short-distance take-off and landing and long-endurance flight, and is economical.

[0003] For aircraft powered by distributed electric propellers, the slipstream generated by the propellers completely changes the flow field properties around the wings. The flow around the...
