Dec 04, 2019

It is reported that this test is to provide a calibration test for the delivery engine of the Long March 8 launch vehicle. The main purpose is to verify the large nozzle of the engine and obtain the performance data of the "Sky" engine to verify whether it meets the delivery requirements.

In the test, the engine was shut down normally after completing all the test procedures, the test process system and test system worked normally, and the test was successfully completed.

The leader of the Long March 8 development team stated that the Long March 8 launch vehicle is a new type of rocket launched by China Aerospace Science and Technology Group Co., Ltd. in the face of strong market demand. It adopts a combination, modularization, and product design to make it commercial and fast. Designed with the goal of convenient manufacturing and operation, and a good trade-off between cost and performance, making it extremely commercially competitive.

The first stage of the Long March 8 carrier rocket inherited the first stage status of the Long March VII carrier rocket, and the second stage of the Long March 3A series carrier rocket inherited the third stage status; the carrying capacity of the solar synchronous orbit reaches 5 tons, and the geosynchronous transfer The orbital carrying capacity reaches 2.8 tons; from the signing of the contract to the delivery of the rocket, the compliance cycle is about 12 months and the launch cycle is about 10 days.

At present, the Long March 8 launch vehicle has entered the production assembly test stage. It is estimated that the annual launch volume in the initial stage of the market can reach more than 10 rounds, and the annual output in the later period can reach more than 20 rounds.
