Planning for Beijing Interstellar Glory Space Technology Co., Ltd. is expected to conduct a “Grasshopper Test” similar to SpaceX in 2021, using a reusable engine independently developed by Interstellar Glory to conduct a sub-class 100-kilometer vertical take-off and landing test. Test to verify the performance of the entire one-child recovery. Among them are two key technologies: the variable thrust technology of the liquid oxygen methane engine and the re-entry recovery navigation guidance and control technology. In the second half of 2021, Interstellar Glory will execute the first launch of the Hyperbolic II small liquid oxygen methane-powered reusable launch vehicle into orbit and recycle one sub-stage……

Precursor On April 1, 2021, the Focus One reusable liquid oxygen methane engine (hereinafter referred to as “Focus One”) independently developed by Interstellar Glory successfully completed the 500-second simulated flight variable thrust test, and the engine was at 50% to Continuous and stable work within 100% thrust range. The test drive successfully assessed the variable thrust adjustment process of Focus One during the rocket from take-off to landing. So far, the Focus One engine has all the conditions to perform the vertical take-off and landing (VTVL) flight test.



This test run is the fifth full-system hot test of Focus One’s (fourth) engine. The five test runs are centred on the Hyperbolic II reusable launch vehicle that will be carried out this year. VTVL missions carry out targeted assessment and verification. The core includes pre-cooling process verification before flight, post-processing process verification upon return, matching verification of self-developed measurement and control system and engine, verification of multiple ignitions and reusability, and verification of reusability. Simulation flight thrust adjustment verification, etc.



The successful completion of the above test indicates that the Focus No. 1 engine is ready for the first-stage vertical take-off and landing (VTVL) flight test of the Hyperbolic No. 2 reusable launch vehicle.

The ability of the engine to have a wide range of continuously variable thrust is the core key to the rocket’s vertical take-off and landing, and it is also the basis for repeated use. For a launch vehicle that achieves repeated use through vertical take-off and landing (VTVL), only by achieving variable thrust, the rocket can be recovered in a controlled manner and reused. The Merlin 1D engine used by SpaceX meets the rocket’s vertical take-off and landing (VTVL) requirements through 70%-100% variable thrust capability and realizes the repeated use of the Falcon9 rocket.

Compared with the traditional fixed thrust and step variable thrust liquid rocket engines, the large-scale continuous variable thrust puts forward higher requirements on the engine system and key components. The control system and the engine system need to work together. At the same time, the thrust of the engine Components such as chambers and turbo pumps must adapt to changes in working conditions during the thrust adjustment process, and be able to work stably in the full thrust range.

Interstellar Glory technical team worked closely and brainstormed together, through numerical simulation and semi-physical simulation and other technical means, after many component and whole machine tests, successfully broke through the engine’s 50% to 100% thrust adjustment technology, and Focus One became the first in China. A low-temperature engine with complete and large-scale variable thrust test results.

The Focus One engine has passed many large-scale continuous thrust changes; secondary start, swing and flight thrust adjustment tests, and is the meter, Kilometer, and hundred kilometers vertical take-off and landing (VTVL) of the Hyperbolic II reusable launch vehicle. ) The test has made sufficient technical preparations, which will also lay the foundation for the follow-up Hyperbola-2 maiden flight mission.

In the future, Interstellar Glory’s engine variable thrust technology can also meet the needs of higher-level precision orbits and even soft landings on the surface of outer planets. On the basis of greatly reducing the cost of launch vehicles in and out of space, it will further meet the diversified needs of commercial aerospace customers …

On July 8 Wednesday, 2020,  iSpace -Beijing Focus Interspace Technology Co., Ltd (referred to as “Interplanetary Glory”). independently developed Focus One (codename “JD-1”) reusable liquid oxygen methane engine successfully passed the continuous variable thrust Long-distance test run , test run time 200 seconds. This test verified the correctness of the JD-1 thrust adjustment system, and obtained accurate data on the JD-1 continuously variable thrust function and performance. The test was a complete success. According to public information, this is the first time that China has completed a large-scale continuous thrust adjustment test for a pump-type cryogenic engine……

In which iSpace in which it is the first Chinese Private Space Company to do so successfully commercially first out from sixty known private space companies in China..  founded in Beijing 2016 located in Beijing Economic and Technological Development Zone or known for short as E-Town… launching the SQX-1 Y1 from one of many CNSA-China National Space Administration launching complexes, launching from Jiuquan Satellite Launch complex, in which is situated in North East China…. Located at the Gobi Desert Inner Mongolia ……

In this test, the thrust was continuously changed from high operating conditions to low operating conditions, and then to high operating conditions. The “V” shape changes to cover the actual flight conditions . In order to ensure the smooth progress of the continuous thrust adjustment test, the Star Glory Mirror Laboratory also conducted a semi-physical simulation test and simulated test test of the engine thrust adjustment before the test . This is the first domestic simulation test of a liquid rocket engine thrust adjustable system, which has broken through the key simulation test technology of liquid rocket recycling.

 The engine’s ability to continuously change thrust is a necessary condition to realize the vertical recovery technology of the launch vehicle, and it is also one of the core technologies. The variable thrust rocket engine can achieve the best thrust control on the one hand, thereby achieving precise control of the rocket recovery and return process; on the other hand, it can also accurately control the overload during the flight of the carrier rocket, ensure flight safety, and provide a good mechanical environment for the satellite condition.

 JD-1 achieved continuous variable thrust test this time. Compared with the traditional stepped variable thrust, the engine thrust adjustment control system can drive the flow adjustment valve to continuously adjust the flow of propellant, which can not only achieve continuous thrust It can also control the mixing ratio of the thrust chamber under variable thrust conditions.

In order to ensure the ability of JD-1 to continuously change the thrust, Interplanetary Glory has designed semi-physical simulation tests of engine thrust adjustment control law, engine system fault diagnosis and control reconstruction, engine controller, flow adjustment mechanism, low temperature continuous medium adjustment valve, engine thrust control , Simulated test drive test and many other aspects have made technical breakthroughs, and were verified in this test drive:

 JD-1 is a 15-ton reusable liquid oxygen methane engine independently developed by Interstellar. The engine adopts a multi-purpose design idea, derived from a basic type of fixed thrust to form a variable thrust type and a vacuum type total of three types of engines. The components can be shared, which is conducive to reducing the development cycle and funding. It is understood that both the engine 15 ton thrust by way of the multi-parallel as a basis a rocket powered, may be a rocket engine as a single vertical or upper stage power recovered power, a balance type two requirements . Prior to this, JD-1 has completed several long-range system-wide test runs and two start-up test runs in succession, with a cumulative test run time exceeding 2200 seconds. In the follow-up, JD-1 will continue to carry out ground tests such as swing test run, engine vibration mode test, various engine boundary tests, engine life and reliability test run test and so on.

  In the future, the JD-1 series configuration engine will be used on the reusable launch vehicle “Hyperbola II” independently developed by Interplanetary Glory, with 9 units installed in the first stage and 1 unit installed in the second stage . The company plans to break through the 100-kilometer vertical take-off and landing test of the hyperbolic No. 2 subclass one and fully master the reusable launch vehicle technology, and will perform the first flight of the hyperbolic No. 2 launch vehicle in 2021 . At that time, the company will master the reusable technology of the liquid propellant launch vehicle, and realize another leap-forward improvement of my country’s commercial aerospace capabilities in space.
