Auxiliary power generation system driven by stamping turbine and using method

Abstract

The invention discloses an auxiliary power generation system driven by a stamping turbine. The auxiliary power generation system comprises an engine, a main power generator, an air-entraining valve, an auxiliary power device, an auxiliary power generation system body and a power distribution system, wherein a rear air-entraining channel of the engine is connected with the air-entraining valve, andthe air-entraining valve controls airflow to be distributed to an environment control system and the auxiliary power device; a comprehensive controller is connected with and controls the air-entraining valve; a turbine power device rotates through air entraining of the engine, and the turbine power device is in mechanical transmission connection with an auxiliary power generation device; and current generated by the auxiliary power generation system body is transmitted to the power distribution system. According to the auxiliary power generation system driven by the stamping turbine, an emergency function and an auxiliary function are integrated, the redundancy backup problem after a main bus bar breaks down is solved, reliability and safety are improved, and emergency power supply time is prolonged; the main bus bar and the auxiliary power generation system body work together, so the whole power supply capacity in the task stage is improved; and through the comprehensive design of acontroller, the resource overhead is saved, the system cost is reduced, and the system matching is improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft power supply design, and relates to an aircraft auxiliary power generation system 5 system and a use method, in particular to a ram turbine driven auxiliary power generation system 5 system and a use method. Background technique [0002] With the continuous development of aviation technology, aircraft electrical equipment has increased sharply, which puts forward higher requirements for power supply system capacity, power supply quality and reliability. For long-endurance unmanned aerial vehicles, due to the extended emergency power supply time requirements, the emergency power supply The power demand has also increased significantly. In order to meet the requirements of aircraft development and the current situation of a single main bus bar with limited capacity, it is urgent to develop an auxiliary power generation system, which not only increases the total power capacity of the system, but also...
