Abstract

The invention discloses a distributed type hybrid power system based on an aviation piston engine and belongs to the technical field of aerospace. The distributed type hybrid power system is mainly composed of the aviation piston engine, a coaxial type electric generator, fuel tanks, a rectifier, a system controller, motors, propellers and the like. The aviation piston engine generates power to drive the coaxial type electric generator to generate electricity, and through conditioning of the rectifier, electric energy of the electric generator or a standby battery is distributed by a system management module to the motors to drive the propellers to generate thrust or lift force.

Description

technical field [0001] The invention relates to a distributed hybrid power system based on an aviation piston engine. It belongs to the field of aerospace technology. Background technique [0002] At present, the power system of small fixed-wing or rotary-wing aircraft is generally an aviation piston engine or an electric motor directly drives the propeller to generate thrust or lift. The aviation piston engine has the advantages of high energy density and long battery life, but has the problem of unstable speed control; while the electric system has good control stability, but due to factors such as large battery weight and low energy density, the flight time is relatively short. short. In order to take into account the advantages of long flight time and control stability of the aircraft at the same time, it is necessary to develop a new type of power system. The distributed hybrid power system based on the aviation piston engine disclosed by the present invention takes ...
