General advanced upper stage of solid launch vehicle

The invention provides a general advanced upper stage of a solid launch vehicle. The general advanced upper stage of the solid launch vehicle comprises an electrical part and a structural part. The electrical part is composed of an integrated electronic system single machine and a peripheral unit. The integrated electronic system single machine comprises a center control module, a signal collecting module, a measurement and control communication module, an attitude and orbit control module, a sequential control module and a power source and thermal control management module which are integrated and connected through a bus. The peripheral unit comprises an attitude control peripheral, a measurement and control communication peripheral, a power source peripheral, a propulsion peripheral and a thermal control peripheral. The structural part comprises a load mounting plate, an attitude control ring, a storage box, an instrument bay, a single machine mounting plate and a propulsion mounting plate, wherein the load mounting plate, the attitude control ring, the storage box and the instrument bay are sequentially connected from top to bottom, and the single machine mounting plate and the propulsion mounting plate are mounted in the instrument bay. The general advanced upper stage of the solid launch vehicle adopts modular design, mutual coupling and interference are effectively reduced, and the flexibility of system configuration is greatly improved; and mechanical/electrical/thermal integrated design is achieved, and cable connection between single machines is avoided, so that systematic complexity is obviously reduced, and system reliability is improved.
