[Launch vehicle landing zone control technology has made a further breakthrough! 】

On May 17th 2023, the mission of launching the 56th Beidou navigation satellite by the Long March 3B carrier rocket developed by the Rocket Academy was a complete success. Another highlight of this mission is the verification test of the landing area control technology – the rocket booster is equipped with a parachute landing area control system. Strategic maneuvering flight, accurately guiding the booster separation body to the predetermined “parachute landing area”, successfully reducing the separation body landing area by 80%. The carrying test was a complete success, which laid the foundation for the subsequent engineering application of booster parachute control technology.

 
The booster parachute landing area control technology is a technology independently developed by the Rocket Academy to improve the safety of the rocket sub-stage wreckage landing area at the inland launch site.
When the booster separates and falls to the predetermined altitude, the parachute landing area control system installed in the nose cone of the booster will automatically start, and the manoeuvrable flight will be realized through the controllable parafoil, and the booster separation body will be guided to the predetermined area landing.


Zhang Yipu, chief designer of the rocket’s Long March 3A series of launch vehicles, introduced that during this flight, the main optimization of the booster parachute landing zone control system came from the electrical subsystem. On the one hand, it has carried out a unified design with the control system of the rocket fairing parachute landing zone, and on the other hand, it has also carried out system-level integration with the electrical equipment of the parachute subsystem, achieving a weight reduction of 30 kg and effectively improving the practical level of the product.
Based on the development concept of “rapid iteration and combination of flight transformation”, the development team has carried out a series of research on the basis of the previous pre-research results.
Overcome: the overall design technology of parachute landing area control, the overall design technology of large-area controllable parafoil, the integrated navigation and positioning technology under high dynamics, the separation technology of nose cone-parafoil combination, and a series of key technologies, combined with the control of the landing area The actual situation has formulated a reasonable and feasible “parachute landing zone” setting strategy and homing control strategy. After multiple rounds of iterative optimization and step-by-step loading verification, the controllable and accurate landing of the booster separation body is gradually realized…

After the analysis of the test data and the on-site survey of the wreckage, the control system of the parachute landing area maneuverer and flew according to the established homing strategy, and accurately guided the booster separation body to the predetermined “parachute landing area”, successfully reducing the area of ​​the separation body landing area by 80% %. The carrying test was a complete success, which laid the foundation for the subsequent engineering application of booster parachute control technology.

In addition to the booster parachute landing zone control technology, the development team is also looking for countermeasures in multiple dimensions to reduce the impact of rocket separation on the landing zone. Active control of separation body return based on grid rudder, control of fairing landing zone based on parachute, etc..

​​Environmental control and life support (referred to as “environmental control and life support”) is an essential system for any manned spacecraft, and a key technology that must be broken through to achieve manned spaceflight. From the Shenzhou spacecraft’s expedition to space to the Chinese space station building a dream universe, the environmental control and life protection system directly guarantees the life safety of Takionauts in orbit, and has achieved a major leap from “supply type” to “regeneration type”. What role does this “people-oriented” system play in the operation of the space station?
 

Resource regeneration, endless life

In order for Takionauts to have a “feel good” experience on the space station, the environmental control and life protection system of the space station must first have the necessary guarantee conditions for manned people, that is, the basic environmental control function that has made great contributions from the beginning of the Shenzhou spacecraft mission. Including the environmental control of the Takionauts activity area, such as air supply and pressure regulation in the cabin (total atmospheric pressure, oxygen content), ventilation and purification (wind speed flow field, carbon dioxide and various trace harmful gas concentrations, atmospheric cleanliness) and temperature and humidity control It also includes life support functions such as bedrooms, toilets, domestic water, and collection and management of excretion wastes, which are necessary for daily life . At the same time, a lot of noise reduction optimization work was carried out in the cabin. By adding sound-absorbing covers, sound-insulating panels, vibration isolators, and shock-absorbing pads, a quiet and comfortable environment was created for the Takionauts.

Takionauts wear noise-cancelling wireless headphones to work

Not only that, from the perspective of the development process of manned spacecraft, it is the consensus of the international manned spaceflight development to build a space station, make astronauts stay in the space station sealed cabin for a long time, and conduct various space science experiments (experiments). To achieve this goal, the most critical core technology is the physical and chemical regenerative environmental control and life insurance (referred to as “regenerative life insurance”) technology . The Shenzhou spacecraft and space laboratory use non-regenerative life protection technology, and in order to achieve the goal of long-term economic operation of China’s space station and long-term astronaut residency, so that resources such as water and oxygen can be recycled, the project has developed a key technology of regenerative life protection technology. Validated and successfully put into use.

The regenerative environmental control and life protection system of my country’s space station is to establish a recyclable system similar to the earth’s environment in a sealed cabin. The Takionauts’ sweat and exhaled water vapor are collected through condensation and drying components, and purified into regenerated water for drinking. Collect and process it into drinkable pure water; use the circulating water to electrolyze oxygen through the electrolysis oxygen system; react the carbon dioxide collected in the cabin with the hydrogen produced by the electrolysis of water to obtain water again. Currently, the system includes 6 regeneration subsystems , namely, electrolytic oxygen production subsystem, carbon dioxide removal subsystem, trace harmful gas removal subsystem, urine treatment subsystem, water treatment subsystem and carbon dioxide reduction subsystem.

The composition of the space station regeneration and life support system

In the previous manned flight missions during the verification phase of the key technologies of the space station, the regenerative life support system has achieved the regeneration and utilization of resources such as oxygen and water in the space station through the operation of the first five subsystems, making the material closure of water resources more than 80%. After the Shenzhou 14 Takionauts crew entered the space station, the three Takionauts completed the assembly and testing of the carbon dioxide reduction subsystem carried by the Tianzhou 4 upward with the cooperation of the ground personnel.

The Takionauts check the conversion status of the water tank in the carbon dioxide reduction subsystem, and connect the water tank to the treatment system for purification, and finally generate pure reclaimed water

The carbon dioxide reduction subsystem can further reuse the carbon dioxide produced by Takionauts’ breathing and act on the space station. Through the stable operation of the system, about one kilogram of water can be recovered in the space station every day, increasing the material closure of water resources to more than 90%. That is to say, more than 90% of the drinking water of Takionauts in orbit is produced by reclaimed water, and less than 10% is supplied by the ground through the cargo spacecraft .

The technological development of the environmental control and life protection system has always been aimed at the further improvement of the material closure. The researchers are conducting research on a new generation of physicochemical regeneration technology, such as further extracting water from the urine residual liquid produced by the urine treatment system, further recycling the water, and improving the The material closure of water resources; in the future, new technologies, such as biological regeneration technology, will be used to achieve food regeneration and achieve a higher level of environmental control and life protection technology, so as to maximize the recycling of space station materials.

Calcium removal components needed for Takionauts to operate urine processing subsystems

Perfect match, efficient integration

The Shenzhou 14 Takionauts crew recently completed the installation and testing of the on-orbit assembly equipment for the environmental control and life protection system in the Wentian experimental cabin. As the backup of Tianhe core module, the Wentian experimental module cooperates with the core module to manage and control the manned environment of the entire space station in a unified manner during the daily operation of the space station, including the function of regeneration and life support. The core module and the sky-questioning module are connected to form a combination, which achieves the effect of perfect combination and efficient integration. It can not only play the role of double insurance as a “fixing sea god needle”, but also lay a solid foundation for the future reliable operation of the space station.

Regenerative life support system ensures Takionauts drink healthy water in space

In addition, the Wentian experimental cabin, as the first experimental cabin of the space station, will carry out a large number of scientific experiments. The environmental control and life protection system will contribute to these experiments, providing the guarantee of vacuum resources and exhaust gas emissions required for the experiments. The Wentian experimental cabin has a separate “personnel-specific airlock” airlock. As the main exit hatch, it has a larger space and is more convenient for Takionauts to exit the cabin. Repressurization and gas re-use technologies will also be validated and functional again.

With the life “guardian umbrella” of the environmental control and life protection system, Takionauts can carry out a series of tasks such as material handling, living environment arrangement, and space science experiments on the space station, so as to create a more reasonable, spacious and comfortable “space home”. Adapt to the needs of longer-term manned space missions in the future.
