Abstract
This application relates to the field of aircraft technology, specifically providing an aircraft power system and an aircraft, aiming to solve the problem that current aircraft power systems cannot meet the high reliability requirements of missiles. To this end, the aircraft power system provided in this application includes: a DC bus, N power compartments, and N switch modules, wherein the nth power compartment is connected to the DC bus via the nth switch module. Each switch module includes two first switches and a cable. One of the two first switches connects one end of the cable to the DC bus, and the other of the two first switches connects the other end of the cable to the corresponding power compartment, where 1 ≤ n ≤ N. This application achieves the goals of improving the reliability and fault tolerance of the aircraft power system, enabling rapid response to power system failures, and flexibly adjusting the power supply mode, thus solving the problem that aircraft power systems cannot meet the high reliability requirements of missiles.
