Dongfang Space announced that the joint thermal test of the booster stage solid motor and servo mechanism of Dongfang Space's "Gravity-1" launch vehicle was a complete success on September 15. The booster stage solid engine tested this time is the main power system of the "Gravity-1" carrier rocket in the take-off and booster flight stages , and it can also be used as a core- stage recoverable "Gravity-2" booster stage. More than 150 tons , the design of bundled 4 boosters makes "Gravity-1" take off thrust up to 600 tons.
Solid boosters are an important choice for medium and large launch vehicle boosters in the world because of their convenience and reliability, fast launch preparation, and high thrust.
Dongfang Space said that during the test, the engine ignition and the whole process worked normally, the internal ballistic performance met the design expectations, the engine and the servo mechanism worked together in coordination and matching, and the engine structure was complete after the test, which verified the correctness and work of the engine and servo mechanism design scheme.
According to reports, the complete success of this test marks that the solid power system of the "Gravity-1" carrier rocket has successfully completed various ground assessment tests in the initial stage, and has begun to enter the stage of large-scale production, laying a solid foundation for the rocket's first flight next year. foundation .
