A kind of gun pod waste gas flow guiding device, including the undercut shape structure being made of cambered surface and semi-open type flow-guiding channel, undercut shape structure is mounted on gun pod body front end and covers tampion, and undercut shape structure forms three face semi-open types to tampion and surrounds, and then aircraft gun exhaust gas is prevented to spread to the air intake duct direction of aircraft two sides;In front under the action of air incoming flow, aircraft gun exhaust gas is spread along aircraft gun exhaust gas flow-guiding channel to the back lower place.The present invention, to construct flow-guiding channel and then change the flow direction of aircraft gun exhaust gas, to realize the target for reducing the air intake duct aircraft gun exhausted air quantity for entering aircraft two sides with the smallest cost, guarantees the normal operation of engine by installing gun pod waste gas flow guiding device additional.
Description
Technical field
The present invention relates to the pneumatic diversion technology field of aircraft more particularly to a kind of gun pod waste gas flow guiding devices.
Background technique
The gun pod plug-in ability one of standing as fighter plane is mounted, when gun pod is mounted on aircraft belly air inlet
When in front of road, the exhaust gas that aircraft gun generates is back into aircraft side inlet.Aircraft gun exhaust gas into airplane intake reduces
The degree of purity of engine charge results even in engine and surge occurs to influence to influence the normal working performance of engine
Failure.
Summary of the invention
Technical problem solved by the invention is to provide a kind of gun pod waste gas flow guiding device, to solve above-mentioned background
Disadvantage in technology.
Technical problem solved by the invention is realized using following technical scheme:
A kind of gun pod waste gas flow guiding device, including the undercut shape knot being made of cambered surface and semi-open type flow-guiding channel
Structure, undercut shape structure are mounted on gun pod body front end and cover tampion, and undercut shape structure is to gun muzzle hat
It is surrounded at three face semi-open types, and then aircraft gun exhaust gas is prevented to spread to the air intake duct direction of aircraft two sides;The air incoming flow in front
Under effect, aircraft gun exhaust gas is spread along cambered surface and semi-open type flow-guiding channel to the back lower place, by installing gun pod exhaust gas water conservancy diversion
Device guides aircraft gun waste gas flow direction, so that the aircraft gun exhausted air quantity into aircraft side inlet is reduced, to guarantee engine just
Often work.
In the present invention, undercut shape structural openings are gradually reduced from front end to end, and first in undercut shape structure
Left side wall is longer than right side wall at section (I-I);Left side wall is longer than right side wall at second section (II-II), while the first section (I-
I right side wall ratio left side wall thickness at), left side wall ratio right side wall thickness at the second section (II-II);Semi-open type flow-guiding channel bottom is arc
Face constitutes aircraft gun exhaust gas flow-guiding channel with left side wall, the right side wall of undercut shape structure.
In the present invention, the undercut shape structure of gun pod waste gas flow guiding device prevents aircraft gun exhaust gas to aircraft two sides
The diffusion of air intake duct direction, the air incoming flow in front spread aircraft gun exhaust gas to the back lower place along aircraft gun exhaust gas flow-guiding channel;?
Under the conditions of meeting aircraft gun routine use, requirement light-weight, that structure is simple and at low cost is combined, by gun pod
Installing waste gas flow guiding device additional just can be reduced the air intake duct aircraft gun exhausted air quantity into aircraft two sides.
The utility model has the advantages that the present invention, which passes through, installs gun pod waste gas flow guiding device additional, with building " aircraft gun exhaust gas flow-guiding channel "
And then change the flow direction of aircraft gun exhaust gas, the air intake duct aircraft gun exhausted air quantity for entering aircraft two sides is reduced to realize with the smallest cost
Target, guarantee the normal operation of engine.

Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
As shown in FIG. 1 to FIG. 2, the tampion 1 of common aircraft gun is mounted on outside gun pod main body 2, part aircraft gun when setting off firecrackers
Exhaust gas is discharged in the horizontal direction to two sides, easily enters the air intake duct 3 of aircraft two sides, to influence engine work.
Referring to a kind of gun pod waste gas flow guiding device of Fig. 3~Fig. 9, including by cambered surface and 5 structure of semi-open type flow-guiding channel
At undercut shape structure gun pod is installed in 2 front end of gun pod main body to reduce influence of the aircraft gun exhaust gas to engine
Waste gas flow guiding device 4, and gun pod waste gas flow guiding device 4 covers tampion 1, to avoid aircraft gun exhaust gas to aircraft two sides
The diffusion of 3 direction of air intake duct.As shown in figure 9, the undercut shape structure of gun pod waste gas flow guiding device 4 forms three to tampion 1
Face semi-open type is surrounded, and then aircraft gun exhaust gas is prevented to spread to 3 direction of air intake duct of aircraft two sides;In the effect of front air incoming flow
Under, aircraft gun exhaust gas is spread 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 guidance aircraft gun waste gas flow directions, so that the 3 aircraft gun exhausted air quantity of air intake duct into aircraft two sides is reduced, to guarantee the normal of engine
Work.
In the present embodiment, undercut shape structural openings are gradually reduced from front end to end, take wherein at two section I-I and
II-II is as shown in Figure 5,6, wherein at the section I-I, the left side wall of undercut shape structure is longer than right side wall;At the section II-II,
The left side wall of concave-shaped structure is longer than right side wall, and right side wall ratio left side wall thickness at the section I-I, left side wall ratio at the section II-II
Right side wall thickness;5 bottom of semi-open type flow-guiding channel is cambered surface simultaneously, constitutes aircraft gun with left side wall, the right side wall of undercut shape structure
Exhaust gas flow-guiding channel.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
