Long March 8 engine high-altitude simulation test successfully met delivery requirements

On November 25, the long march 8 rocket engine high-altitude simulation test was successful. The main purpose of the test is to verify the large nozzle and obtain the performance data of the engine and to meet the delivery requirements. This test is to provide the long march 8 to provide the delivery engine calibration test, the test engine completed all the test procedures after the normal shutdown, the test process system and test system work normally, the test was a complete success.

Staff are preparing for the test.

Recently, Tang Yihua, vice president of China Aerospace Science and Technology Group Co., Ltd., said at the 5th China (International) Commercial Space Summit Forum: “Long March 8 will achieve its first flight in 2020.” “

Long March 8 carrier rocket is a new type of rocket launched by the Aerospace Science and Technology Group in the face of the commercial market, the Long March 8 carrier rocket core one stage inherited the Long March 7 carrier rocket one sub-state, the core second stage inherited the Long Three-A series of carrier rocket three sub-state.

Long March 8, relying on the successful and reliable technology of the first flight of China’s new generation launch vehicle, is expected to fill the gap of 3 tons to 4.5 tons of carrying capacity in China’s solar synchronous orbit in the future, taking into account the launch capability of low-Earth orbit and geosynchronous transfer orbit, with moderate launch cost, shorter launch cycle, and adapt to the conditions of multiple space launch sites. With strong international competitiveness, the market prospects for commercial satellite launches are optimistic.

The rocket’s solar synchronous orbit carrying capacity can reach 5 tons and the geosynchronous transfer orbit carrying capacity can reach 2.8 tons. The Long March 8 carrier rocket has a performance period of about 12 months and a launch cycle of 10 days from the signing of the contract to the time the rocket leaves the factory.

Tang Yihua said that the Long March 8 carrier rocket is expected to enter the market, the initial annual launch capacity of more than 10 rounds, the latter annual output of more than 20 rounds.
