I have stated to build a prototype of the engineer, Good luck for me.

I think the biggest difficulties to realize the new type of jet engine are: 1. Some parts bear the unstable forces. I calculate and compare the several solutions to choose...

Feasibility and improvement solution: When I firstly proposed the idea in my patent(That patent has been out of valid time), I didn’t use the blower or compressor in my engine....

Calculate the temperature before the turbine: Pls see below figure 4: The method also is used to calculate the temperature of each course. Under some condition, when the pressure after...

The figure 3 shows the gas pressure at different courses (in different places), it is rough, and the exact details will is rather complicated. There might be a little mistake....

Working cycle analyses and efficiency (please see figure 2) Estimate the theoretic efficiency; compare the two types of engines: the current engine and I proposed. Firstly I state some premises:...

Firstly I explain the structure in brief. （figure 1） The left one is the section along axial, it show almost all main parts. Another two pictures show the main parts:...

The jet propulsion with closed combustion type I have an idea of a new type jet engine, I explain it here and hope somebody study it and advise me how...

I heard that people ever tried the constant-volume combustion type gas turbine engines many years ago and gave up later. I think the reason is that the engine was heavy...

to propose this new engine, I also studied many books about this field. Most of them in Chinese, I can not translate the information of reference book into English. It...
