    In the control system of aerospace vehicles, springs are key actuating components. For example, the reset spring of missile servos can accurately control the deflection angle of the control surface, and the torsion spring of satellite attitude adjustment mechanisms can stably maintain the in orbit attitude, ensuring flight trajectory and operational accuracy;
    In the engine system, the locking spring of the turbine blade can fix the blade position, withstand high temperature and high pressure gas impact, and avoid blade loosening and failure; The compression spring of the fuel nozzle controls the opening and closing of the fuel injection valve, ensuring stable fuel atomization and supply, and assisting the efficient operation of the engine;
    In the landing and recovery process of spacecraft, springs play a buffering and protective role. For example, the buffering springs of the landing legs of the spacecraft can absorb the huge impact force at the moment of landing, reduce damage to the cabin and internal equipment, and ensure the safety of astronauts and payloads;
    In aerospace precision instruments such as gyroscopes and star sensors, miniature springs can isolate vibration interference, maintain the stability of internal components, ensure the accuracy of navigation and measurement data, and provide reliable data support for aircraft flight control and mission execution.
