completed the long march five. Two rocket flight failure investigation, at the end of this year will be the implementation of Long March five. Three

rocket launch on 16 April, Xinhua news agency, Beijing (reporter Yu Xiaojie) 16 reporter learned from SASTIND fault Long March five. Two rocket flight lost recently improved the basic identification. The core level of liquid rocket engine ground test complete repeatedly, verify the effectiveness of the improvement measures. In July 2nd

2017, the long march five remote two rocket was launched at the Wenchang space launch site in Hainan, and the rocket broke down for 346 seconds. According to the analysis of simulation and ground test results, the fault reason is the core level of liquid rocket engine turbo exhaust extension in the complex stress thermal environment, abnormal local structure, instantaneous thrust fell sharply, resulting in the launch failure.

at present, the development team of Long March five launch vehicle is developing the remote three rocket based on the full implementation of the measures for improving the faults, and plans to launch at the end of 2018. Follow up, the long march five remote four rocket will carry out the mission of the Chang'e five detector in the three phase of the lunar exploration project.
