Title:

AIRCRAFT PROPULSION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2022/082962

Kind Code:

A1

Abstract:

An aircraft propulsion system. The system comprises: a control apparatus, rotary power sets and fixed power sets, wherein the control apparatus is used for sending a target working mode to the rotary power sets and the fixed power sets according to an aircraft control instruction; the rotary power sets are used for adjusting, according to the target working mode, the directions and working states of all propellers in the rotary power sets; and the fixed power sets are used for adjusting, according to the target working mode, the working states of all propellers in the fixed power sets. By means of the aircraft propulsion system, there is no power deadweight in an aircraft control system, the weight of an aircraft is reduced, and flight control over the aircraft is optimized, thereby improving the utilization efficiency of the overall power system of the aircraft. Moreover, since the rotary power sets and the fixed power sets of the aircraft propulsion system are arranged in a distributed layout, the fault tolerance of the power system is improved, thereby ensuring the safety of the aircraft.
