The invention discloses an embedded type gas charging channel for supplementing gas for a gas charging channel based on a high-pressure gas cylinder. The embedded type gas charging channel comprises a gas charging hole, a gas discharging hole and a gas flow passage of a gas charging channel, wherein the gas charging hole is connected with the gas discharging hole by virtue of the gas flow passage of the gas charging channel; a gas spraying hole is formed in the inner wall of the gas flow passage of the gas charging channel and is communicated with the high-pressure gas cylinder by virtue of a gas flow guide pipe; the gas flow guide pipe is provided with an automatic control valve. According to the embedded type gas charging channel for supplementing gas for the gas charging channel based on the high-pressure gas cylinder, the gas spraying hole is formed in the gas flow passage of the gas charging channel; the gas in the high-pressure gas cylinder is supplemented for the gas charging channel by virtue of the gas flow guide pipe and the gas spraying hole; the total pressure recovery coefficient of the gas charging channel in a starting stage of an engine is increased; meanwhile, the gas flow is increased.
Description
Technical field
The present invention relates to a kind of Submerged Inlet, particularly relate to a kind of for carry-on based on the Submerged Inlet of gas cylinder to intake duct tonifying Qi.
Background technique
Submerged Inlet is combined together at import and aircraft, without any the special intake duct of protruding part.Submerged Inlet not only effectively can reduce frontal resistance and the radar scattering area of aircraft because wind-exposuring area is little, and the fusion of itself and body makes the size of body reduce, and is conducive to installing, transport and multi-platform transmitting.Therefore, Submerged Inlet is being subject to paying close attention to more and more widely and applying.
Submerged Inlet and conventional admission road are as compared with S shape intake duct, and total pressure recovery is on the low side, flow distortion is larger.Particularly at engine start ignition phase, Submerged Inlet total pressure recovery coefficient is low to moderate about 0.80.Therefore, improve small flow state inlet characteristic and will contribute to the starting of motor high-altitude ignition.
Therefore, need to provide a kind of new technological scheme to solve the problems referred to above.
Summary of the invention
The problem lower for engine start-up phase Submerged Inlet total pressure recovery coefficient and exit flow flow is lower, the technical issues that need to address of the present invention are to provide the Submerged Inlet that a kind of temporary transient total pressure recovery coefficient is higher and exit flow flow is higher.
For solving technical problem of the present invention, the technical solution used in the present invention is:
Based on the Submerged Inlet of gas cylinder to intake duct tonifying Qi, comprise suction port, air outlet and inlet flow passage, suction port is by inlet flow expanding channels air outlet, the inwall of described inlet flow passage is provided with fumarole, described fumarole is communicated with by airflow duct with described gas cylinder, and described airflow duct is equipped with autocontrol valve.
Described fumarole to be positioned at before intake duct on lip guide face.
The boring region width circumferentially of described fumarole is 1/3 ~ 1/2 of this position intake duct width.
Described fumarole is the equally distributed array of aperture of dozens of diameter several millimeters.
The described fumarole ejection angle of air-flow and the angle of wall tangent line should be less than 30 °.
Airflow duct between described gas cylinder and fumarole should form extending section flexible pipe in the position near fumarole.
At engine start-up phase, the air-flow that the pressure of being come by bleed conduit by gas cylinder is higher is sprayed by fumarole, improve inlet total pres sure recovery coefficient, add air flow rate simultaneously, when motor enters normal state, slowly close the tonifying Qi of gas cylinder to intake duct by autocontrol valve.
Of the present invention based on the Submerged Inlet of gas cylinder to intake duct tonifying Qi, inlet flow passage offers fumarole, gas in gas cylinder passes through airflow duct--and-fumarole is toward tonifying Qi in intake duct, improve engine start-up phase inlet total pres sure recovery coefficient, add air flow rate simultaneously.

Wherein, 101, suction port, 102, air outlet, 103, inlet flow passage, 104, fumarole, 105, extending section flexible pipe, 2, gas cylinder, 3, airflow duct, 4, autocontrol valve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.Following examples, only for illustration of the present invention, are not used for limiting the scope of the invention.
With reference to figure 1, of the present invention based on the Submerged Inlet of gas cylinder to intake duct tonifying Qi, comprise suction port 101, air outlet 102 and inlet flow path 10 3, suction port 101 connects air outlet 102 by inlet flow path 10 3, the inwall of inlet flow path 10 3 is provided with fumarole 104, fumarole 104 is communicated with by airflow duct 3 with gas cylinder 2, airflow duct 3 is equipped with autocontrol valve 4.
Fumarole 104 to be positioned at before intake duct on lip guide face; The boring region width circumferentially of fumarole 104 is 1/3 ~ 1/2 of this position intake duct width, the smooth position namely on guide face; Fumarole 104 is the equally distributed array of aperture of dozens of diameter several millimeters, is generally being less than 10 row along airflow direction, is circumferentially being less than 10 row; In order to obtain good result, the angle of angle and wall tangent line that fumarole 104 sprays air-flow should be less than 30 °, needs the wall thickness ensureing that bore position is suitable for this reason; Airflow duct 3 between gas cylinder 2 and fumarole 104 should form extending section flexible pipe 105 in the position near fumarole 104, can cover fumarole array.
Inlet flow path 10 3 offers fumarole 104, and the gas in gas cylinder 2 toward tonifying Qi in intake duct by airflow duct 3---fumarole 104, is improve engine start-up phase inlet total pres sure recovery coefficient, adds air flow rate simultaneously.
At engine start-up phase, by using gas cylinder 2, jet toward intake duct fumarole 104, air flow rate in intake duct is supplemented.Improve outlet total pressure recovery coefficient with this and increase air flow rate, thus improving based on the performance of gas cylinder to the Submerged Inlet of intake duct tonifying Qi; When motor normal table works, the tonifying Qi of gas cylinder 2 pairs of intake ducts just slowly can be closed by autocontrol valve 4.There is good engineer applied be worth.
The present invention is not only applicable to Submerged Inlet, but also is applicable to engine start-up phase total pressure recovery coefficient and air flow rate other type intake duct on the low side.
