Embodiment

Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.

As shown in Figure 1, on blade 1, be arranged on rotor 2, the rotation of rotor drive vane, rotor and blade have integer rotating ratio (for example, 2 to 1, be that 360 ° of rotors are than 180 ° of blade rotaries), make blade have identical form in the same space position, end cap 3 inner chambers and blade face are tangent, and two blades and end cap surround sealed air chamber, in the time of rotor, the volume of air chamber changes.

Gear 5 is fixed on the axle of rotor 2, upper and lower two gears of transition gear 6 are coaxially connected, the spatial position of its axle is fixed, transition gear 6 driven gears 7 rotate, the rotation of final band moving vane, the number of teeth of blade gear should be the integral multiple of blade quantity, for example, in the time that the number of blade measures 8, the number of teeth of gear should be 8 or 8 integral multiple.

With present engine with compared with detonation mode, adopt sustained combustion mode can reduce shock and vibration, air chamber is with certain speed process fuel injector igniter 4, in the time of the anterior arrival of air chamber oil nozzle position, it is commencement of fuel injection, igniting immediately, enter the sustained combustion stage, until air chamber leaves fuel injector igniter, sustained combustion can make air chamber temperature be ladder distribution, improve local temperature, the too high meeting of turbogenerator exhaust velocity causes kinetic energy rejection, and piston engine rotating speed is restricted, therefore, these motors all adopt higher compression ratio (compression ratio of piston engine machine is in 10:1 left and right at present), there are not these problems in the present invention, rotating speed is substantially unrestricted, provide high-power output can adopt more high-revolving way, consider in conjunction with air chamber sealing condition, therefore, the present invention can adopt relatively low compression ratio.

Turbosupercharger 8 utilizes waste gas as motivational drive, and has reduced the pressure reduction between suction port and relief opening, reduces air chamber sealing requirement.

Because blade is symplex structure, its rotation can not change barycenter, and rotor is axisymmetric, so the barycenter of whole rotor is constant, can not change with rotation, and coincide with axle center, has eliminated preferably eccentric vibrating problem.

Blade and end cap can adopt heat insulation good pottery to manufacture, or adopt heat insulating coat, reduce heat loss, raise the efficiency, and blade also can adopt hollow structure.

Gap between blade and end cap is comparatively crucial, after mixed gas burning, produce high pressure, owing to there being multistage blade before and after firing chamber, and pressure successively decreases step by step, consider that again under high speed conditions, to maintain time of high pressure very short, therefore, a small amount of Leakage Gas is acceptable, if can rationally control leakage rate, keep there is one deck gas film between blade and end cap, play lubrication, also have to utilize and improve engine efficiency, solve cylinder wear and the friction energy-dissipating problem of reciprocating engine, and can extend the working life of motor.

Motor temperature rise and pressure change can affect impeller clearance, can adopt more following measures to improve, and one, adopt the less material of thermal distortion, or utilize thermal distortion to do Contrary compensation; Two, the gap width that contrived experiment is suitable; Three, research blade surface applies repair materials, and its hardness, lower than cap material, in the time there is friction, is consumed blade surface coating material; Four, increase blade quantity and optimize blade profile; Five, install elastic device additional, allow blade to swing at a small angle range; Six, adopt turbosupercharging, improve suction port and exhaust pressure.

Rotor shaft can be made hollow, as the lubrication passage of internal rotor gear and sharf.

Fig. 2 is a kind of regular inner chamber example, compared with Fig. 1 structure, is mainly blade axis of rotation direction difference, and the blade axis of rotation is parallel with main shaft here, and blade 9 is installed on rotor 10, the 11st, and fuel injector igniter, the 12nd, stator, the 13rd, charging turbine.

Same aforementioned principles, rotor and blade rotational speed degree ratio are 2 to 1, and the cross section of blade 9 is oval, is 2:1 if get ellipse long and short shaft, and it is circular can making bore of stator, is conducive to the processing of stator.

Engine temperature is along with the operating time raises, arriving certain value will tend towards stability, while considering engine operation, air chamber produces axial force, the axial clearance of rotor and stator is increased, and firing chamber one side clearance increases more, uncertain output torque also affects this gap, roller 14 can limit this gap to be changed, can optimize roller 14 and clamping support size thereof by test, intensity and thermal expansion factor, also stator faces can be contacted to blade-section and be designed to adjustable structure, to adjust the gap between blade and end face, and the gap of blade and stator sidewall can be adjusted by blade angle, way is the spatial position of fine setting transition gear axle.

Fig. 3 is a kind of tradeoff design example, process relatively simple, adopt the processing of conventional mechanical process equipment, bore of stator can adopt the moulding of line cutting process, and blade 15 is arranged on rotor 16, and blade and rotor speed ratio are 1 to 1 and switched in opposite, see that from ground blade does not rotate, 17 waste airs of relief opening are by the driving force as turbo charging installation, and suction port 18 and suction port 19 connect turbo charging installation, and the effect of suction port 18 is the waste gas blowing out in rotor.In this application example, blade is eccentric, if be applied to high rotating speed, blade can adopt hollow-core construction, and eliminates eccentric in the counterweigh of the two ends of its axle.The 20th, fuel injector igniter.
