An aero-engine direct-drive internal rotor starter-generator system, which is applied in the field of unmanned aerial vehicle hybrid electric power, installs and fixes the starter-generator outer stator assembly on the aero-engine through a stator bracket, so that the starter-generator system has a compact structure and Short length, high integration, and high power-to-weight ratio; the coaxiality between the starter generator stator and the engine is ensured through the support of the stator bracket, and the starter generator inner rotor assembly is directly installed on the aeroengine shaft, so that the starter generator system There is no need for bearing support near the engine side, and a single bearing support is used on the far engine side, which reduces the heat generation of the bearing and improves the reliability of the bearing; there is also a resolver at the end of the rotor assembly in the starter generator far away from the aeroengine, which can accurately Detect the position of the rotor, so that the starter generator system can output high-power direct current by means of controllable rectification, and the power generation efficiency is high.

The invention discloses a vibrative charging tank with a liner plate. The vibrative charging tank comprises a tank body and the tank bottom liner plate, wherein the head portion of the tank bottom liner plate is fixedly connected with the tank body bottom through a transversely-arranged bolt assembly, the tail portion of the tank bottom liner plate is fixedly connected with the tank body bottom through a vertically-arranged bolt assembly. When the charging tank works, the tank body performs horizontal reciprocating vibration, the transversely-arranged bolt assembly provides a horizontal fastening force for the tank bottom liner plate and accordingly can effectively resist horizontal vibration inertia force and horizontal friction force enabling the liner plate to be loosened, and the vertically-arranged bolt assembly provides vertical fastening force for the tank bottom liner plate and accordingly can effectively resist vertical inertia force enabling the liner plate to be loosened. In addition, pre-compression amount of a spring gasket can automatically compensate a gap produced between a nut and an elastic gasket when the liner plate vibrates, and nut loosening can be avoided. Therefore, the vibrative charging tank has the advantages that the liner plate and the tank bottom are tightly connected, the liner plate is not loosened when working for a long period of time, and the charging tank is stable in running, small in maintenance work amount, long in service life and the like.
