Description
Technical field
The utility model relates to a kind of jet engine, especially adopts the jet engine of battery and chemical fuel combination drive.
Background technique
At present, practical jet engine is divided into ramjet type motor, intermittent jet and turbojet motor three major types.Ramjet type motor must could be worked under very high speed, the problems such as life-span of vibrations when intermittent jet is limited to work and suction port one-way valve, and above-mentioned two class jet engines are only applied at special occasions.Now widely used is turbojet motor, must have the high-speed rotary parts such as gas compressor and turbine due to turbojet motor, complex structure, and cost is very high, is difficult to use on a large scale aspect miniaturization.Turbine must be worked under high temperature and high rotating speed, not only requires highly, and has limited the raising of fuel gas temperature, makes the efficiency of turbojet motor be difficult to further raising.
At miniaturization context engine, there is a kind of electronic ducted fan formula motor recently, with high-speed brushless motor, drive ducted fan rotation to realize low speed jet propulsion.Because the power-weight ratio of battery is much smaller than chemical fuel, therefore, use electronic ducted fan formula motor that electric energy promotes to be extremely restricted having an high regard on the when operating time completely, only on model airplane, be applied at present.
Summary of the invention
The purpose of this utility model is to overcome the problem that above-mentioned various jet engine exists, and provides a kind of employing gas compressor to calm the anger, but again can widely used jet engine without turbine and the simple in structure of transmission shaft drive gas compressor work.
Another object of the present utility model is to overcome electronic ducted fan formula motor to have an high regard for the restriction being subject on the when flight time, and a kind of jet engine that adopts battery and chemical fuel combination drive is provided.
The technological scheme that the utility model adopts is: the electronic jet engine of calming the anger is comprised of intake duct, gas compressor, high-speed brushless motor, firing chamber, jet pipe, compressor air inlet machine end is fixedly connected with intake duct, gas compressor outlet side is fixedly connected with chamber front end, rear end, firing chamber is fixedly connected with jet pipe, and compressor impeller is directly driven by high-speed brushless motor.The electronic jet engine of calming the anger also includes fuel tank, oil feed pump or supplies solenoid, electronic speed regulator, electrokinetic cell, fuel oil in fuel tank enters firing chamber by oil feed pump or for solenoid, electronic speed regulator inlet side is electrically connected to electrokinetic cell, and electronic speed regulator goes out end respectively with high-speed brushless motor and oil feed pump or be electrically connected to linkage for solenoid.
When the electronic jet engine of calming the anger is worked, high-speed brushless motoring compressor impeller High Rotation Speed, by intake duct air amount compression, air pressure is raise, flowing in combustion chamber, in firing chamber, violent burning after mixing with air by oil feed pump or for the fuel that solenoid sprays into, after burning, the flue gas of High Temperature High Pressure sprays at a high speed acting by jet pipe.By electronic speed regulator, control the rotating speed of high-speed brushless motor and the fuel delivery of oil feed pump or confession solenoid simultaneously, when high-speed brushless motor speed raises, the air quantity that enters firing chamber increases, and fuel delivery also increases simultaneously, and the electronic jet engine output power of calming the anger strengthens; When high-speed brushless motor speed reduces, the air quantity that enters firing chamber reduces, and fuel delivery also reduces simultaneously, and the electronic jet engine output power of calming the anger reduces.
The electronic jet engine gas compressor of calming the anger can adopt centrifugal-flow compressor, also can adopt axial-flow compressor.
Compared with prior art, the beneficial effects of the utility model are: cancelled the high-speed rotary parts such as turbine and transmission shaft, jet engine structure is simplified greatly, cost significantly reduces, can also by improving fuel gas temperature, improve the efficiency of jet engine, be particularly useful for miniaturization jet engine, the electric energy that battery provides is only for driving gas compressor, required electric energy is much smaller than electronic ducted fan formula motor, all can reach usage requirement having an high regard on the when operating time.
If gas compressor adopts centrifugal-flow compressor and for radially giving vent to anger, in the situation that not affecting engine power, intake duct is vertical with jet pipe axis with firing chamber with gas compressor axis, aircraft can directly be realized back or belly air inlet.
