[0002] The aircraft power supply and start-up module is the execution module in the aircraft flight control device. Usually, the aircraft power supply and start-up module is designed to power and start a single aircraft. The module size is required to be about 40mm×180mm×280mm, and the weight is not more than 2kg. The internal space utilization rate and density of the module are low. When the flight control device powers and starts multiple flight devices, a large number of aircraft power supply and start-up modules are required, the overall weight and occupied space are large, the overall density of the flight control device is low, and the space utilization rate is low.

[0003] Under the premise of meeting the use requirements, the weight and volume requirements of the aircraft power supply and start module are often too redundant, resulting in the characteristics of low density and heavy weight of the module. The volume and weight of the aircraft power supply and start module in the launch control device account for more than 50%. Therefore, in order to reduce the overall volume and weight of the flight control device, it is necessary to design a high-density, lightweight and reliably protected aircraft power supply and start module.

[0008] Preferably, a protection circuit is further included, in which a rectifier diode is connected in reverse parallel to the relay control end of the protection circuit to prevent back electromotive force from damaging components.
