Description

A kind of novel pulsed motor

Technical field

The utility model relates to a kind of air breathing engine, is specifically related to a kind of pulsed motor.

Background technique

At present, the design of various hovercars is all based on folded wing, and the mechanical mechanism weight required owing to folded wing is bigger, has not only increased the requirement to motor power, and has increased fuel consumption and technical difficulty; Make hovercar not only rarely have appearance, and the minority model that has occurred also is difficult to promote.Therefore, a kind of motor of hovercar that is applicable to more of design will be significant.

The model utility content

The technical problem that the utility model will solve provides a kind of novel pulsed motor that is applicable to hovercar.

The technological scheme that the utility model solves this technical problem is:

A kind of novel pulsed motor; Have motor body, be provided with vertical air flue of double as firing chamber and air jet pipe in the motor body, a port of this air flue is a suction port; Another port is for advancing spout; Wherein, suction port is provided with the rotary type one-way valve, advances spout to be provided with and advances the spout valve; The bottom of said air flue is provided with the landing spout, and this landing spout is provided with unidirectional valve; The top of said air flue is provided with fuel tank, and the fuel tank bottom is provided with the spray bar that stretches in the air flue at the end near suction port, and spray bar is provided with nozzle; Be provided with horizontal wing in the air flue between said spray bar and the propelling spout.

The described pulsed motor of the utility model, wherein, described unidirectional valve is made up of the gentle gate control spring of valve plug.

The working principle of the pulsed motor of the utility model is following: before the engine operation, the rotary type one-way valve is in open mode; During the work beginning, rotary type one-way valve and the valve-closing of propelling spout, the oil of oil nozzle ejection and the air mixing in the air flue, and by spark ignitor; High-pressure gas sprays downwards from the landing spout; After the high-pressure gas ejection, because the effect of inertia of gas flow, though the pressure in the air flue is equal with the pressure of outside atmosphere; Still can continue outside spray; So in air flue, cause the phenomenon of rarefaction of air, pressure significantly is reduced to less than barometric pressure, so air flows into air flue from the rotary type one-way valve of opening once more; The oil spout ignition begins second circulation; Thereby completion self-starting process.In the above-mentioned jet process, can be through the control high-pressure gas from the landing spout or advance to gush out the spout and realize vertical lifting or advance.Because the motor of the utility model is arranged at the part of wing as motor in the air flue; Making can be owing to the space reduces to be compressed when air flow stream is crossed between wing the space; When the speed of the motor racing of using this motor reaches certain value; This wing just can produce enough lift, makes automobile be in regime of flight.

Can know by top description; The pulsed motor of the utility model both can have been realized the promotion of vertical direction; Also can realize the promotion of substantially horizontal; Simultaneously wing and motor are combined, be applied in the weight that can alleviate automobile on the hovercar, it is applied in the beneficial effect that can produce on the hovercar is conspicuous.

Fig. 1～Fig. 7 is the structural representation of an embodiment of the described pulsed motor of the utility model, and wherein, Fig. 1 is a plan view, and Fig. 2 is a plan view; Fig. 3 is the A-A sectional view of Fig. 1, and Fig. 4 is the B-B sectional view of Fig. 1; Fig. 5 is the C-C sectional view of Fig. 2; Fig. 6 is the I place partial enlarged drawing of Fig. 4; Fig. 7 is an axonometric drawing.

Embodiment

Referring to Fig. 1～Fig. 7, the pulsed motor of the utility model has motor body 1, is provided with air flue 2 longitudinally in the motor body 1, and this air flue 2 is both as the firing chamber of motor, also as air jet pipe.The two ends of air flue 2 are provided with opening, and one of them port is a suction port 3, and another port is for advancing spout 4; Suction port 3 is provided with rotary type one-way valve 5, and the rotating shaft of this rotary type one-way valve 5 is located at the middle part of suction port 3; Advance spout 4 to be provided with to advance spout valve 6, this propellings spout valve 6 is made up of stigmal plate 7 and the control piece 8 of controlling these stigmal plate 7 unlatching moments, and this control piece 8 is a coil, controls the unlatching moment of stigmal plate 7 through the energising of control coil.

Referring to Fig. 1～Fig. 5, the bottom of air flue 2 is provided with four landing spouts 16, and each landing spout 16 is provided with one-way cock 9, and this one-way cock 9 is made up of valve plug 10 gentle gate control springs 11.

Referring to Fig. 1～Fig. 7, the top of air flue 2 is provided with fuel tank 12, and the bottom of this fuel tank 12 is provided with nine spray bars 13 that stretch in the air flue 2, and these spray bars 13 are located at the position near suction port 3 abreast, and each spray bar 13 is provided with a plurality of nozzles 14.

Referring to Fig. 1, Fig. 3～Fig. 5, air flue 2 inherences are advancing the part between spout 4 and the spray bar 13 to be provided with a plurality of horizontal wings 15.

When in the hovercar that the motor of the utility model is packed into, motor is at first discharged pressurized gas through landing spout 16 to the air cushion of car body bottom, thereby makes the car body built on stilts; Advance spout 4 to open afterwards, vehicle travels forward, and automobile can obtain enough lift from wing 15 and make automobile entering regime of flight during to certain speed.

Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technician in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
