Abstract
The utility model provides a boat big gun nacelle waste gas guiding device, includes fall the character cut in bas -relief shape structure that comprises cambered surface and semi -open type water conservancy diversion passageway, the underway big gun nacelle main part front end of fall character cut in bas -relief shape structrual installation covers the tampion, and the shape of falling character cut in bas -relief structure is to the encirclement of the trilateral semi -open type of tampion formation, and then the prevention is navigated big gun waste gas and is spread to the intake duct direction of aircraft both sides, under the effect of the place ahead air incoming flow, boat big gun waste gas spreads to the back lower place along boat big gun waste gas water conservancy diversion passageway. The utility model discloses an install boat big gun nacelle waste gas guiding device additional to found the water conservancy diversion passageway and then change the flow direction of boat big gun waste gas, thereby realize with the cost of minimum that the reduction gets into the target of the intake duct boat big gun waste gas volume of aircraft both sides, guarantees the normal operating of engine.
Description
Technical field
The utility model is related to the pneumatic diversion technology field of aircraft, more particularly to a kind of gun pod waste gas flow guiding device.
Background technology
Gun pod is mounted as one of standing plug-in ability of fighter plane, when gun pod is mounted on aircraft belly air inlet
During road front, the waste gas that gun is produced is back into aircraft side inlet.Gun waste gas into airplane intake is reduced
The degree of purity of engine charge, so as to affect the normal service behaviour of engine, results even in engine and surge occurs
Failure.
Utility model content
The technical problem that the utility model is solved is to provide a kind of gun pod waste gas flow guiding device, above-mentioned to solve
Shortcoming in background technology.
The technical problem that the utility model is solved employs the following technical solutions to realize：
A kind of gun pod waste gas flow guiding device, including the undercut shape knot being made up of cambered surface and semi-open type flow-guiding channel
Structure, undercut shape structure is arranged on gun pod body front end and covers tampion, and undercut shape structure is to gun muzzle hat
Surround into three face semi-open types, and then prevent gun waste gas from spreading to the air intake duct direction of aircraft both sides；Air is flowing in front
Under effect, gun waste gas spreads along cambered surface and semi-open type flow-guiding channel to the back lower place, by installing gun pod waste gas water conservancy diversion
Device guiding gun waste gas flow direction, so as to reduce the gun exhausted air quantity into aircraft side inlet, to ensure engine just
Often work.
In the utility model, undercut shape structural openings are gradually reduced from front end to end, and in undercut shape structure
Left side wall is longer than right side wall at I-I sections；Left side wall is longer than right side wall at II-II sections, while（I-I）Right side wall ratio at section
Left side wall thickness,（II-II）Left side wall is than right side wall thickness at section；Semi-open type flow-guiding channel bottom is cambered surface, with undercut shape knot
The left side wall of structure, right side wall constitute gun waste gas flow-guiding channel.
In the utility model, the undercut shape structure of gun pod waste gas flow guiding device prevents gun waste gas to aircraft two
The air intake duct direction diffusion of side, the air in front causes gun waste gas along gun waste gas flow-guiding channel to back lower place expansion to flow
Dissipate；Under the conditions of gun routine use is met, while the requirement of lightweight, simple structure and low cost is taken into account, by gun
Installing waste gas flow guiding device on gondola additional just can reduce air intake duct gun exhausted air quantity into aircraft both sides.
Beneficial effect：By installing gun pod waste gas flow guiding device additional, to build, " gun waste gas water conservancy diversion leads to the utility model
The flow direction in road " and then change gun waste gas, so as to realize reducing useless into the air intake duct gun of aircraft both sides with minimum cost
The target of tolerance, it is ensured that the normal operation of engine.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Fig. 1～Fig. 2, the tampion 1 of common gun is arranged on outside gun pod main body 2, part gun when setting off firecrackers
Waste gas to both sides are discharged in the horizontal direction, easily into the air intake duct 3 of aircraft both sides, so as to affect engine work.
Referring to a kind of gun pod waste gas flow guiding device of Fig. 3 ~ Fig. 9, including being made up of with semi-open type flow-guiding channel 5 cambered surface
Undercut shape structure, be to reduce impact of the gun waste gas to engine, gun pod is installed in the front end of gun pod main body 2 and is given up
Gas guiding device 4, and gun pod waste gas flow guiding device 4 covers tampion 1, to avoid gun waste gas entering to aircraft both sides
Spread in the direction of air flue 3.As shown in figure 9, the undercut shape structure of gun pod waste gas flow guiding device 4 forms three faces to tampion 1
Semi-open type is surrounded, and then prevents gun waste gas from spreading to the direction of air intake duct 3 of aircraft both sides；In front, air is come the effect flowed
Under, gun waste gas spreads along cambered surface and semi-open type flow-guiding channel 5 to the back lower place, by installing gun pod waste gas flow guiding device
4 guiding gun waste gas flow directions, so as to reduce the gun exhausted air quantity of air intake duct 3 into aircraft both sides, to ensure the normal of engine
Work.
