The joint thermal test of Dongfang space booster solid engine and servo mechanism has been successful.

Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com, September 17, yesterday, Oriental Space announced that the joint hot test test of the booster stage solid motor and servo mechanism of the Eastern Space "Gravity 1" carrier rocket was a complete success on September 15.

The booster-stage solid motor tested this time is the main power system of the "Gravity-1" carrier rocket during take-off and booster flight, and it can also be used as the core-stage recoverable "Gravity-2" booster stage, with a thrust of more than 150 tons per unit. The design of bundling four booster makes the take-off thrust of "Gravity No.1" as high as 600 tons.

CTOnews.com learned that solid booster is an important choice for medium and large launch vehicle booster in the world because of its convenience and reliability, fast launch preparation and high thrust.

Oriental Space said that in the test, the ignition and the whole process of the engine worked normally, the interior ballistic performance met the design expectations, the engine and the servo mechanism worked together to coordinate and match, and the engine structure was complete after the test. the correctness and reliability of the design scheme of engine and servo mechanism are verified.

According to reports, the complete success of this test indicates that the solid power system of the "Gravity-1" carrier rocket successfully completed various ground examination tests in the initial sample stage and began to enter the stage of large-scale production, laying a solid foundation for the rocket's first flight next year.
