March 20 News: The privately-developed rocket company, Beijing Blue Arrow Space Technology Co., Ltd. independently developed the 'Phoenix' 10-ton liquid-oxygen methane engine thrust room to test successfully. China's private aerospace companies achieved breakthroughs in the independent research and development of liquid rockets, and liquid oxygen methane. The rocket's commercialization process will further accelerate.
The 10-ton liquid methane engine thrust chamber for this test has completely independent intellectual property rights. 'We named the Phoenix as a liquid methane rocket engine, which means auspiciousness and harmony. It's soaring. 'The chief designer Wang Minghang said,' In 2017, the test of this type of engine gas generator was successful. By now, the success of the thrust room test has been solved. We have solved a series of technical problems in the development of the liquid engine and also solidified the foundation for the development of the blue arrow liquid engine.
'Developing aerospace, power first', the engine is the core of the rocket, and the thrust chamber is the core component of the liquid rocket engine. Whether the thrust chamber can work safely and reliably and provide enough thrust is the key to the success or failure of the launch vehicle. Liquid rocket The engine represents the highest technological level of private carrier rockets. Methane as a propellant has low cost, low coking, low viscosity, strong cooling capacity, and high specific impulse (impact per unit of propellant, liquid oxygen methane up to 390.3/second, much higher. For solid fuels, etc., it is currently the mainstream of research on international commercial rocket engines, and to some extent represents the future of commercial aerospace power technology.
The world's leading privately-owned liquid-propellant rocket engines, such as SpaceX's new Raptor (Raptor) and blue-origin BE-4, are all liquid oxygen methane engines. They are stable, reusable, etc. Compared to solid-state engines, liquid engines The development cycle is long and difficult. For private aerospace companies, developing a liquid engine is a test and challenge for their technical capabilities and company strength. The success of this test marks the first domestic emergence of liquid oxygen. Private commercial aerospace companies with core technologies for methane engines also make China the second country in the world that has independently developed high-performance liquid oxygen methane engines for private enterprises.
At present, the private aerospace industry has broad market prospects. With the increasing demand for applications such as satellite networking and satellite constellation, it will require a higher level of launch and launch capabilities in the future. At the same time, it also means that more advanced and more reliable products are needed. Aerospace companies and higher quality space transportation services.
