Description
Technical field
Cigarette technical field, more particularly to a kind of gun pod smoke guide device are led the present invention relates to aircraft is pneumatic.
Background technology
For gun pod is arranged on the middle-size and small-size aircraft of ventral, due to placement constraint, gun pod is typically installed
In the front lower place of airplane intake, when aircraft gun shoots especially multiple running fire, produced HTHP waste gas is moved back from gun muzzle system
The both sides of device and front discharge, are easily inhaled into airplane intake, so as to cause engine surge or even parking；In order to the greatest extent may be used
Influence of the aircraft gun shooting to engine work can be reduced, it is necessary to design a kind of device so that HTHP waste gas is as few as possible
It is inhaled into airplane intake.
The content of the invention
Technical problem solved by the invention is to provide a kind of gun pod smoke guide device, to solve above-mentioned background technology
In shortcoming.
Technical problem solved by the invention is realized using following technical scheme：
A kind of gun pod smoke guide device, including closed lead cigarette structure, and closing by what polylith dividing plate and smoke guide shell body were constituted
Formula is led cigarette structure and gun pod and melted as an assembly, and assembly is arranged on the front lower place of airplane intake, and aircraft gun gun muzzle system
Device is moved back to be wrapped in assembly；Dividing plate is arranged in smoke guide shell body, and the front end and lower section of smoke guide shell body offer lower row respectively
Gas port, makes the HTHP waste gas discharged originally from muzzle brake both sides and front transfer from the front end and lower section of smoke guide shell body
The discharge of lower exhaust outlet, while passing through the barrier effect of dividing plate, when waste gas is from the discharge of the lower exhaust outlet of smoke guide shell body, reduce boat
The exhausted air quantity of airplane intake is sucked when big gun is shot, and then improves inlet engine compatibility efficiency, it is ensured that engine work.
In the present invention, trajectory through hole is provided with dividing plate, so that shell can smoothly be projected from smoke guide shell body.
In the present invention, closed cigarette structure of leading is cylinder, and 2 times of its a diameter of aircraft gun muzzle brake external diameter.
In the present invention, closed cigarette structure length of leading is 10 times of aircraft gun muzzle brake external diameter.
In the present invention, closed lead is provided with three pieces of dividing plates in cigarette structure, and first piece of dividing plate is moved back with aircraft gun gun muzzle system
The distance of device is 25 millimeters, and remaining dividing plate spacing gradually increases.
Beneficial effect：The present invention is by installing gun pod smoke guide device additional, to change the flow direction of aircraft gun waste gas, effectively solves
Aircraft gun shoot produced waste gas into airplane intake cause engine surge the problem of, with it is simple in construction, lightweight, be easy to
The characteristics of installing and safeguard.
Brief description of the drawings
Fig. 1 is gun pod waste gas smoke guide device and airplane intake scheme of installation in presently preferred embodiments of the present invention.
Fig. 2 is the sectional view of presently preferred embodiments of the present invention.
Fig. 3 is the upward view of presently preferred embodiments of the present invention.
In accompanying drawing, 1, smoke guide shell body, 2, gun pod, 3, airplane intake, 4, aircraft gun muzzle brake, 5, dividing plate, 6,
Trajectory through hole, 7, lower exhaust outlet.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Referring to a kind of Fig. 1 ~ Fig. 3 gun pod smoke guide device, including the envelope being made up of polylith dividing plate 5 and smoke guide shell body 1
Enclosed leads cigarette structure, and closed cigarette structure and the gun pod 2 of leading melts as an assembly, and assembly is arranged on airplane intake 3
Front lower place, aircraft gun muzzle brake 4 is wrapped in assembly；Dividing plate 5 is arranged in smoke guide shell body 1, before smoke guide shell body 1
End and lower section offer lower exhaust outlet 7 respectively, turn the original HTHP waste gas discharged from the both sides of muzzle brake 4 and front
And the lower exhaust outlet 7 from the front end of smoke guide shell body 1 and lower section is discharged, while by the barrier effect of dividing plate 5, in waste gas from leading cigarette
When the lower exhaust outlet 7 of housing 1 is discharged, the exhausted air quantity of airplane intake 3 is sucked when reducing aircraft gun shooting, and then improves inlet engine compatibility
Efficiency, it is ensured that engine work；And trajectory through hole 6 is provided with dividing plate 5, so that shell can be suitable from smoke guide shell body 1
Profit is projected.
In the present embodiment, closed cigarette structure of leading is cylinder, for reduction aerodynamic drag, and diameter is unsuitable excessive, is protecting
Demonstrate,prove under conditions of structural strength, its diameter is about 2 times of the external diameter of aircraft gun muzzle brake 4.
In the present embodiment, on the premise of undercarriage control is not influenceed, closed cigarette structure of leading should have enough length
Degree, with reach it is optimal lead cigarette effect, its length is about 10 times of the external diameter of aircraft gun muzzle brake 4.
In the present embodiment, to ensure that waste gas is mainly discharged from the closed lower exhaust outlet 7 for leading cigarette structure, in construction weight
In the case of permission, the design quantity of dividing plate 5 as many as possible, the present embodiment is using three pieces of dividing plates 5.
In the present embodiment, for ensure it is optimal lead cigarette effect, first piece of dividing plate 5 in the range of aircraft gun shooting reach to the greatest extent
May the distance of first piece of dividing plate 5 and aircraft gun muzzle brake 4 be 25 millimeters in aircraft gun muzzle brake 4, the present embodiment,
Remaining spacing of dividing plate 5 gradually increases.
In the present embodiment, to ensure that shell is not struck against on dividing plate 5, the aperture of trajectory through hole 6 should be according to shell
Spread is designed, and with the distance increase of dividing plate 5 and aircraft gun muzzle brake 4, the aperture of trajectory through hole 6 increases successively
Greatly, but in order to ensure that HTHP waste gas is discharged from the closed lower exhaust outlet 7 for leading cigarette structure as far as possible, shell scattering is being met
Under conditions of scope, each perforate of dividing plate 5 is as small as possible.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
