A Number Of New Material Products Of China National Building Materials Helped The Successful Launch Of Shenzhou 19 Manned Spacecraft

Core tips: at 4:27 Beijing time on October 30, the Long March 2F carrier rocket carrying Shenzhou XIX manned spacecraft was ignited and launched at Jiuquan Satellite Launch Center. About 10 minutes later, Shenzhou XIX manned spacecraft and rocket successfully separated into the scheduled orbit, the astronauts aboard the group in good condition, the launch was a complete success.

 

The Long March-2F carrier rocket carrying the Shenzhou-19 manned spacecraft was fired from Jiuquan Satellite Launch Center at 4:27 Beijing time on October 30. About 10 minutes later, the Shenzhou XIX spacecraft and the rocket successfully separated into the scheduled orbit, the astronauts aboard the

crew in good condition, the launch was a complete success.

 

A number of new material products of China National Building Materials contributed to the successful launch of Shenzhou XIX manned spacecraft and added new achievements in space, providing a reliable guarantee for the construction of a space power.

The large-size, multi-opening propulsion system main bearing thin-wall reinforced cone independently developed and produced by Habo Institute of China Building Materials General Institute is a large carbon fiber composite material product used in the history of manned space flight. The product is a large-size, large-opening, thin-wall (1.2mm at the thinnest point) truncated cone structure, with light weight, high strength, high precision and large bearing capacity. Since 1995, Harbo Institute has undertaken the research and development of the bearing cone of the spacecraft propellant capsule and the installation bracket of the gas cylinder, and has contributed wisdom to the "Shenzhou" series of manned spacecraft for many times.

The 362D time controller developed and produced by the company is used in the re-entry module of Shenzhou XIX manned spacecraft. 362D time controller is a mechanical time controller, which can control the spacecraft to complete the landing according to the program, and has the characteristics of high reliability, high precision, strong anti-interference ability, etc., which provides reliable guarantee for the smooth landing and return of the return

capsule.

The high purity quartz glass with low helium permeability and radiation resistance developed by the North Quartz Institute of the General Institute is applied to Shenzhou XIX manned spacecraft.

As a laser exit window and online monitoring window, the low-permeability helium-resistant high purity quartz glass can not only effectively resist the strong irradiation of cosmic rays, but also has high adaptation coefficient of expansion to ensure the accuracy of flight positioning.

North Glass Co., LTD., a subsidiary of SinOMA Technology, has developed anti-heat/heat insulation integrated medium-density premix used in the key parts of Shenzhou XIX manned spacecraft, and high-performance ablative resin used in the thermal protection plate at the bottom of the Long March 2F remote 19 launch vehicle engine and escape tower. The high strength yarn developed by Nanbo Co., Ltd. is respectively used in the thermal protection structure of the Long March 2F carrier rocket and the heat insulation layer of the return capsule of Shenzhou XIX manned spacecraft. The company's products have reliable performance and excellent quality, providing a reliable guarantee for rocket launch, spacecraft docking with the core module of heaven and earth, and the safe return of astronauts.
