深蓝航天 Deep Blue Limited – Deep Blue Aerospace One of sixty Chinese private space Carrier Rocket Companies in China-People’s Republic of China… As many of sixty plus Private Rocket Deep Blue Aerospace Co., Ltd. was established in 2017. The company is mainly a high-tech aerospace enterprise that focuses on the direction of liquid recovery and reusable launch vehicles and provides users with commercial launch services. Deep Blue Aerospace Co., Ltd. is headquartered in Nantong City, Jiangsu Province. At the same time, the company has rocket general and liquid engine R&D centers in Yizhuang, Beijing and Xi’an, Shaanxi, respectively, and a rocket power system test base in Tongchuan, Shaanxi…..
Flight preparation liquid oxygen kerosene engine successfully completed the first three-start complete machine test run in China, People’s Republic of China.
The “Thunder-R1” engine participating in the test has experienced dozens of start-up tests and ignition tests under different working conditions, as well as more than ten short-range and long-range test runs of the whole machine without leaving the platform, and has excellent reusability.
Through this trial run, the following objectives were achieved: Verified the correctness of the three ignition design states of the “Thunder-R1” engine…
Multiple starts involve key designs such as start-up air consumption distribution and automatic simple post-processing. This test run focuses on verifying the correctness of the design of multiple start-up air consumption distribution and multiple start-up and shutdown processes; The rationality of process design such as automatic post-processing, automatic pre-cooling of oxygen system, and automatic maintenance of non-working section box pressure.
Verified the correctness of multiple ignition timings of the “Thunder-R1” engine
Different from Through this test run, the timing difference between the filling state before multiple starts, the pre-cooling state of the oxygen system and the first ignition was obtained, and the correctness of the design of the ignition sequence, starting sequence, and blow-off sequence during multiple starts and shutdowns was verified.
“Thunder-R1” engine’s successful three-time ignition test is a new milestone in the high-frequency and normalized test run after Shenlan Aerospace’s new vertical test station was put into use, and it also marks the deep blue aerospace in engine design, production and testing. Steady improvement in the whole process capability.
In the follow-up series of vertical recovery flight tests, a series of key technical system-level verifications, including multiple starts of the engine in the air, will be gradually carried out to achieve the successful orbiting of the “Xingyun-1” carrier rocket and the vertical recovery of the first sub-stage. Reusable.
