Abstract

The invention discloses a distributed electric ducted fan power system for short-distance / vertical take-off and landing, and belongs to the field of aviation aircrafts. The system comprises a duct power unit, an upper high-lift airfoil and a lower high-lift airfoil, the duct power set comprises a plurality of duct power units which are arranged in parallel; the end faces of the two sides of the upper high-lift airfoil and the two sides of the lower high-lift airfoil are connected with steering engines installed on the fuselage through connecting rods and located above and below the outer side of an outlet of the duct power set correspondingly, and the rotating angles of the upper high-lift airfoil and the lower high-lift airfoil are controlled through the steering engines. The upper high-lift airfoil comprises an upper high-lift airfoil main wing and an upper high-lift airfoil flap, and the lower high-lift airfoil comprises a lower high-lift airfoil main wing and a lower high-lift airfoil flap. By changing the deflection angle and form of the upper high-lift airfoil and the lower high-lift airfoil, the limitation of a power system on aerodynamic layout is reduced, and distribution and utilization of power in different stages such as take-off and landing and cruising are facilitated.

Description

technical field [0001] The invention belongs to the field of aviation aircraft, and in particular relates to a distributed electric ducted fan power system for short-distance / vertical take-off and landing. Background technique [0002] Aeronautical aircraft can be divided into two categories: rotary-wing aircraft and conventional fixed-wing aircraft. Rotor-type aircraft, such as helicopters, can take off and land vertically, and have relatively low requirements on ground conditions, but generally fly at a low speed. Conventional fixed-wing aircraft fly fast and have a long range, but take-off and landing require sufficient running distance. In order to make up for the defects of fixed-wing aircraft take-off and landing, short take-off and landing aircraft and vertical take-off and landing aircraft appear and develop. [0003] In terms of short take-off and landing, the application of power boosting devices such as air blowing and suction flaps has effectively shortened the...
