Keep improving, the rocket can't afford to fly, don't want to stop
The rocket can't fly, and the double doesn't stop. "We must strive for excellence, not only to ensure the success of the rocket launch, but also to ensure that the process is perfect." When reporting to the superiors in the work of the rocket, the general commander of the rocket Liu Yu was powerful.
Manned space flight, human life is closed. The chief designer of the Rockets, Jing Muchun, revealed to reporters that the rocket has improved reliability and safety through more than 30 technical improvements. In addition, the sufficiency and coverage of the test are further improved, and the assembly process control is quantified. Among them, in order to ensure the safety of astronauts, the semi-physical simulation test of escape accidents was carried out in depth, and 79 state simulations were completed.
On June 7th, the ship cover assembly and the rocket's secondary arrow were successfully docked, and the escape tower was safely “weared†on the “head†of the improved long F rocket. At the work site, the workers have a wide variety of torque wrenches, and the operator constantly adjusts and replaces the wrench.
Liu Yu said: "The rocket launching Shenjiu further carried out the implementation of tightening torque and anti-loose measures. The fasteners with torque requirements or torque retesting accounted for more than 60% of the total number of full-arrow fasteners. The fasteners for loosening measures accounted for 99.6%.†When talking about this problem, the craftsman Lei Yi said, “There are 50 new torque wrenches and screwdrivers that I applied for.â€
Wang Jinshan, who was responsible for closing the rocket door after the three astronauts entered the spacecraft, had a deep understanding of the high standards of manned personnel. He was too tired when working on support adjustments and grid wing installations. Because he knows that these components play a key role in the rocket launch escape mode, it is especially hard.
After the improved Chang'e F rocket entered the launch site on May 9, the work progressed smoothly. Five general inspections were completed and the technical status was normal.
