Azimuth configuration and operation, therefore should not be understood as the limitation to scope of protection of the utility model.
The utility model provides a kind of device reducing helicopter windshield dazzle, is driven with reducing or eliminating helicopter
It sails center console in cabin and projects the dazzle generated on the windshield of front, improve the visual field outside pilot, it is tired to reduce vision
Labor.
As shown in Figure 1, the device that the utility model reduces helicopter windshield dazzle includes mainly：
Sliding rail 3 is arranged in the outer plate surface of the fixation hood 2 of display；
Movable barn door 1 can between the first location and the second location be moved along the sliding rail, the activity barn door
When at first position, the activity barn door is overlapped with fixed hood plate face, when the movable barn door is in the second position
When place, the dazzle that the center console is projected to the windshield is blocked by the movable barn door.
The position relationship schematic diagram that movable barn door 1 is located at first position and the second position is set forth in Fig. 2 and Fig. 3.
Between daytime, movable barn door is in collapsed state, concordant with instrument board hood, does not work.Under night-environment, movable barn door
It is stretched out along the sliding rail on instrument board hood, shelters from the light path that center console light is reflected on windshield glass,
To achieve the purpose that eliminate windshield glass dazzle.Its concrete principle or design procedure are with reference to figure 2 or Fig. 3.Include mainly：
Step 1：Determine the light source position for generating dazzle
The light source position of dazzle is generated using the specificity analysis of light refraction, reflection.
Step 2：Determination need to eliminate the range of dazzle
The dazzle range on windshield glass is determined using ray tracing or test method；
Range and the position of dazzle need to be eliminated according to visual field requirement determination immediately ahead of pilot.
In Fig. 2, center console light source 7 produces light source mirror image 5 on windshield glass 6, and the light source mirror image 5 is to flight
Member's eye position 8 is in same level or windshield glass glare area caused by light source mirror image 5 reduces outside pilot
The visual field.
Step 3：Determine installation site and size
Best position of the barn door on hood is determined using ray tracing or test method；
Barn door optimum size is determined according to the area size that need to eliminate dazzle, it is ensured that can eliminate windscreen in front of pilot
On dazzle.Structure as shown in Figure 1, fixed hood 2 are existing display shading equipment in cabin, the utility model
Movable barn door fitting setting can slide in and out on fixed hood 2 along the sliding rail of setting, i.e., to driver side to cunning
It is dynamic, luminous source mirror is projected as 5 so as to shelter from the center console light source 7 on windshield glass 6.
Step 4：Determine mounting structure
According to barn door installation site and size design mounting structure, the factors such as weight, beauty, intensity, vibration need to be considered；
Include mainly：
Fixed hood 2 is bonded closely with movable barn door 1, and the corner of movable barn door 1 is set as arc rounding off,
With reference to figure 1 comprising in the transition of the vertical angle of board direction, and the rounding off in all sides.
The sliding rail is provided with a plurality of, is evenly arranged on the fixed hood.To ensure the intensity of structure.
The sliding rail is bar shaped slot structure, is provided with corresponding strip projected parts on the activity barn door, the strip is convex
Rising can be contained in the bar-shaped trough, and can be moved along the bar-shaped trough length direction.In the present embodiment, with reference to figure 1, setting
It is T-type structure to have three sliding rails, bar-shaped trough, and same strip projected parts are also corresponding T-type structure, can ensure that strip projected parts are only capable of
Enough length directions along bar-shaped trough move.
In the present embodiment, the thickness at the position with strip projected parts of the activity barn door is more than movable barn door
Thickness at other positions.With reference to figure 1, in order to mitigate weight, in the lower region of intensity requirement, thinning place is carried out to thickness
Reason.
The room being appreciated that, above-mentioned activity barn door either thickeies or thinning processing, the material of movable barn door are equal
For non-transparent material.
The utility model have the advantage that for：
Movable barn door has blocked center console light, is allowed to that reflected image can not be generated on front windshield, to drop
Glare area size on low windshield glass.As shown in figure 3, the area of windshield glass glare area 4 is compared with preceding wind in Fig. 2
The area of gear glass glare area 4 is obviously reduced.
With can draw-in and draw-off function, can be received when not used to concordant with fixed hood, have shrink it is convenient, good appearance excellent
Point.
Activity shading plate shape fairing, similar to fixed shading hood shape, compactness is high, has and is easily assembled, does not influence
The advantages of external visual field.
Movable barn door edge has carried out corners processing, has many advantages, such as good appearance, is not easy to collide with.
Through using ray tracking soft simulation and cockpit luminous environment verification experimental verification, after installing the activity barn door additional, flight
Dazzle area on the windshield of member front is largely reduced, and can effectively improve the external field of view of night flying person, reduction regards
Feel fatigue, is obviously improved helicopter night flight safety, and have little effect to its inside visual field, handling comfort etc..
It is last it is to be noted that：Above example is only to illustrate the technical solution of the utility model, rather than limits it
System.Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should manage
Solution：Its still can with technical scheme described in the above embodiments is modified, or to which part technical characteristic into
Row equivalent replacement；And these modifications or replacements, various embodiments of the utility model that it does not separate the essence of the corresponding technical solution
The spirit and scope of technical solution.
