According to today’s news from the Fifth Academy of China Aerospace Science and Technology Group, from the successful launch on May 5 to the safe return on May 8, the performance of the test ship of the new manned spacecraft generation is perfect, paving the way for a new “heaven” Way. ”The seven key technologies related to the success or failure of the mission have been verified one by one, pointing the direction for the development of the new spacecraft in the next stage.

According to experts from the Fifth Institute, the HAN propellant used in this engine has the advantages of non-toxicity, free of contamination, low freezing point, high density, high specific impulse and low costs of use and maintenance. It will completely replace the existing propellant in the future and further improve the safety of astronauts.
——China’s current spacecraft maximum volume surface tension tank, which was first adopted by the new generation of manned spacecraft test ship, worked perfectly.
This storage tank adopts aluminum alloy lining + composite winding structure, with more carrying capacity, which can provide more track maneuverability for the test boat.
——The new generation of manned spacecraft test craft has a more comprehensive integrated electronics.
In the course of the mission, the system has successfully completed the functions of all ship bus management, time system management, data storage, contact signal processing and thermal control management, making the spacecraft more efficient.
—— The smarter autonomous orbit control technology of the new-generation manned spacecraft test ship has worked well.
During orbital operation, the test ship’s attitude control engine performs attitude control to maintain three-axis attitude to the ground and stability of attitude during orbit change and braking. The orbit-controlled engine achieves multiple changes in orbit and successfully performs return braking, precisely controlling the test ship to complete space flight.
—— In the reentry and return phase, the new heat-resistant structure and materials first used on the test ship of the new-generation manned spacecraft were tested.
The new lightweight heat resistant material used in the test boat return cabin not only withstands high temperature ablation of thousands of degrees during the return return process, but also protects the safety of the return cabin; Reusable rate. After returning to the cab, only a “physical exam” is required and a new heat resistant frame assembly is replaced.
—— Airbag landing and pneumatic group deceleration damping technology first adopted in a new generation of manned spacecraft test boats to escort home.
The return cabin enters the atmosphere. After reaching the specified altitude, the two deceleration umbrellas and the three main umbrellas open one after the other, and the return cabin speed is successfully reduced from “airplane flight speed” to “urban driving speed of the vehicle”. Before landing, all six airbags inflate and open, helping the cabin to “land smoothly” smoothly, ensuring the safe and complete recovery of the return cabin to the fullest extent.
—— Orbit data acquisition system designed for the new generation of manned spacecraft test craft, providing scientific support for future development.
During the mission, the system obtained the spacecraft shock impact load and arrow and launch cargo environment, flying into orbit and returning to the landing process through a variety of sensor networks; measuring the pressure and temperature of the characteristic points on the surface of the lower and lateral return wall. The characteristic aerodynamic and thermal parameters of the high speed reentry process of the return cabin were obtained. These valuable data will provide an important reference for the development and optimization of subsequent models of the new spacecraft.
News from the China Academy of Aerospace Science and Technology mentioned that the success of the test ship mission has marked that China’s new generation of manned spacecraft has taken shape. In follow-up, the Institute will conduct an in-depth demonstration of the overall plan for the new-generation manned spacecraft in accordance with mission requirements, and as soon as possible to upgrade and develop a new-generation manned spacecraft With high carrying capacity and cargo carrying capacity, suitable for near-Earth space stations and manned deep space exploration.
