The jet propulsion with closed combustion type

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 to launch it into market.

Brief structure and main principle:I have an idea of a new jet engine. （It evolves from my patent ZL 95237295.9）The combustion in current jet engine is under constant high pressure created by compressor. A lot of energy out off from combustion chambers is used to drive turbine for compressor. But I know the efficiency of compressor is not high and the compressor is very heavy, its weight occupies 70% of total engine. Further the compressor also consumes about 2/3 proportion of total energy. My idea is to adopt closed combustion type to increase pressure. It consist of several same components cooperate to get stable propulsion. By the closed combustion, we can get high pressure easily. It also utilizes the advantage of closed combustion of mixture gas: easily igniting, burning rapidly; easy to get high pressure. On the other side I must overcome its weakness: the stress on some parts isn’t consistent and regulate difficultly in different work condition. I have thought methods to solve them.
The main advantage is: the new jet engine has more efficiency than current jet engine.
