China's private rockets successfully recovered for the third time (Source: Netease users)
For this test, aerodynamicist and aerospace technology expert Huang Zhicheng told reporters that it is necessary to encourage or not to raise the height. At present, the test conducted by the hacker space station is still a preliminary test in the field of recyclable. "This is a meaningful one. The test, but still far from the level of SpaceX."
Founded in 2014, Vision Aerospace is engaged in the development of repeatable launch and liquid rocket engine technology. The RLV-T5 rocket was completed in May 2018 and was officially put into production. The full-arrow height is 8.1 meters, the diameter of the arrow is 0.65 meters, the takeoff weight is 1.5 tons, and the power system is composed of five variable-thrust liquid rocket engines. It is reported that the Arrow is planned for the early technical exploration of future sub-orbit reusable rockets and in-orbit reusable rockets.
The RLV-T5 rocket was designed to verify the soft landing of low-altitude flights. According to Hacker Aerospace, this test explores a variety of key technologies for rocket recovery, including control techniques combining traditional control algorithms with neural network control algorithms, multiple engine parallel technologies, new ignition start technologies, and new boost technology. Newly validated technologies such as improved ballistic guidance, pneumatic control, and high-speed precision positioning, and simultaneously verified the application of a variety of low-cost industrial-grade devices.
As early as this test, hacker space has disclosed two successful low-altitude flight recovery tests. On the afternoon of March 27th, the RLV-T5 rocket carried out the low-altitude flight recovery test in the first free state in Longkou, Shandong Province and succeeded. The rocket was lifted to 20 meters to complete the 10-second hovering action and landed to the center of the recovery test site. The drop accuracy is better than 50 cm.
On April 19th, also in Longkou, Shandong, Yuke Aerospace completed the second low-altitude launch and recovery test of the RLV-T5 recyclable rocket. The flight time was 30 seconds, the flying height was 40 meters, and the recovery point accuracy was better than 30 cm.
Chu Longfei, CEO of Space Shuttle Aerospace, told reporters that after the success of this test, the optimized RLV-T5 rocket will be tested for multiple kilometers of flight to verify reliability, and the sub-orbit is planned to be completed before the end of the year. The structure of the liquid oxygen methane rocket RLV-T6 can be reused for the first flight in the first half of next year.
