The major countries in the world are all developing "combined engines" and want to combine different types of engines. The characteristic of this engine is that it can adapt to the needs of various airspaces, and it can fly at low altitudes, fly at high altitudes, and even fly in space. Its application range is very broad. According to the latest information, there is good news from China's Xi'an Aerospace Propulsion Research Institute. The domestically-made "combined engine" developed by the institute has successfully passed the test and achieved excellent results.

It is understood that during the test, the “combined engine” of Xi’an Aerospace Propulsion Research Institute completed a 600-second test run, which set a new record in history. You should know that the same type of products tested in the United States have only been tested for 200 seconds. This means that China has come to the front of the United States in the field of "combined engines". According to a domestic media report on September 26, the "combined engine" developed by Xi'an Aerospace Propulsion Research Institute also has three power modes, which combine turbojet engine technology, super combustion engine technology, and rocket engine technology. The meaning of the times.

Conventional "combined engines" generally only use two engine technologies, because it is easier to study. For example, the "combined engine" developed in the United States uses a combination of a turbofan engine and a turbojet engine, which allows the engine to perform better conversion between subsonic and supersonic speeds. Compared with China's "combined engine", the American "combined engine" is undoubtedly much simpler.

The "combined engine" developed by China is actually more like a future technology product, which will be mainly applied to aerospace aircraft. Everyone knows that conventional turbojet engines and turbofan engines can only fly at an altitude of 25 to 30 kilometers. The transcendent ramjet is mainly flying at altitudes of 50 kilometers to 60 kilometers. Once the "near space" (100 kilometers) is exceeded, turbojet engines, turbofan engines, and transcendent ramjet engines have to stop and cannot continue to fly, because these three engines require oxygen during flight, and space There is no oxygen.

If you want to continue flying in space, you have to use a rocket engine. The "combined engine" developed by China combines turbojet engine technology, super combustion engine technology, and rocket engine technology, which means it can be from the ground Fly all the way to space, soar freely in the atmosphere and space. In today's world, there is no engine that can achieve this. The "combined engine" developed by China can be said to have created a historical precedent.

Stop posting stupid articles from that stupid website of yours.

Are these combined cycle engines for the purposes of single stage to space flight? Like the recently test flown spaceplane? Except to take off and fly only on its own power? Are these things currently useful for anything other than cheaply getting smaller satellites into orbit?

The site and source is rubbish but the information is accurate and being reported by these typical "leak" style sources. Combined cycle engine has been tested and flown for "extended" time.

His post adds nothing new. The test flight has been covered here at both the space program thread and hypersonic thread using credible sources. His sh!tty article adds absolutely nothing new, cites no sources, not to mention is a stupid machine translation, and he's been told to stop by multiple people – including a mod – for precisely the same reasons.

You are better active in europe forum or in US forum. Its for references.
If you need another article about it, you can found it, search in google search/yandex search engines, etc, it can found more, not to lazy.

When can we expect new WS15?
New variant of WS10 is said to have thrust close to F119. Will WS15 be near about that zone or will try to match F135?

Xiamen University jiageng-1 rocket,most likely to be used for the combined engine test flight
xiaomi no.1 :rolleyes:

Really? Isn't this particular rocket launched years ago by Xiamen uni and presumably with some PLA funding and interest? What's the Jiageng 1 rocket/vehicle got to do with any combined cycle engine tests which were done by another vehicle just last month?

Huawei no.1! :p
