So far, there is not a human can complete aero engine cover hypersonic speeds from zero to a wide flight envelope. 6 cylinder 2.0 turbocharger Therefore, people build the future "somersault cloud", the most tend to use different ways to use a different flight speed range of the engine relay combinations work.

Compared to "Sabre" jet and rocket engines used in combination, another modular engine - turbo ramjet study of history more glorious, more promising prospects. The US new SR-72 reconnaissance aircraft will use the technology.

60 years of birth and not born "new concept"

Recalling the history of the development of human aviation propulsion device, a concept from a proposal to apply generally takes about 20 years. As the 30s century, German made turbojet engine concept, the 1940s, humans have officially entered the era of jet flight.

However, the turbo ramjet is a special case. In the 1950s, the concept of such a modular engine began to be formed in the United States and Europe, 60 years later, although it is always seen as a new concept engine various papers, but has always been "born without birth." So far, still no one punch combination turbo engine in use, even without any use of a combination of a turbine engine aircraft flight punching reported.

It was asserted that it was "not necessarily a combination of two proven technologies new technologies" are typical examples. 4 cylinder 3.5 turbocharger You know, the human use of a turbine jet engine more than 70 years, while presenting ramjet concept has been a full hundred years.

However, this does not affect people's imagination turbo ramjet bright prospects: 5-8 Mach hypersonic flight, greater than 1000 may be repeated utilization levels in the true sense of the takeoff, horizontal landing, using conventional fuel and lubrication agents, low security ......
