Problems solved by technology
However, all the air sucked by the traditional gas turbine from the outside must be pressurized by the compressor, and the compressor consumes a lot of work, accounting for about 1 / 2 to 2 / 3 of the expansion work.
Secondly, the exhaust gas passing through the gas turbine still has a certain amount of energy, that is, the temperature and pressure have not been fully utilized
Thirdly, the thermal efficiency of the gas turbine is low when the load changes
In short, the thermal power conversion efficiency of traditional gas turbines is low

The invention provides a rotor type engine and relates to the technical field of engines. The rotor type engine comprises three functional levels including a compression level, a combustion level and an expansion level. The rotor type engine is characterized in that all levels are independent to one another and are connected in series into a whole through a main shaft, and each level is composed of one or more heating power conversion units. The heating power conversion units comprise compressors, combustors and expansion machines at different functional levels. The engine is mainly composed of a main rotor, an auxiliary rotor, a shell and a timing device; main components are all subjected to revolved body machining, the outer diameter of the main rotor is tangent to that of the auxiliary rotor and is two times that of the auxiliary rotor, and the angular speed of the auxiliary rotor is two times that of the main rotor; and the shell contains fixed air feeding openings and exhausting openings, the timing device is a cylindrical piece containing a circumferential air opening, and the timing device and the shell are subjected to sealed treatment through comb teeth. Core components of the compressors, the combustors and the expansion machines are all served as the timing device.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine system with high efficiency, low emission, high power density and high reliability. Background technique [0002] After a hundred years of development, the efficiency of traditional engines is still at a relatively low level. The recognized efficiency of internal combustion engines has reached more than 30%. However, with the improvement of efficiency, environmental protection has become more and more difficult. "event" is a fact; gas turbines on airplanes or ships adopt the principle of isobaric circulation, and their efficiency is low. Combined steam generation. [0003] In order to improve the thermal efficiency of internal combustion engines, traditional reciprocating piston internal combustion engines reuse the energy of exhaust gas, generally using exhaust gas turbocharging, such as supercharged diesel engines and supercharged gasoline engines. However, the ener...
