This driving cabin windscreen with sunshade ability has been avoided aircraft cockpitIn common mechanical type solar protection devices may occur disturb unit occupant sight line because solar protection devices is saggingPhenomenon, has alleviated the weight of aircraft when reducing unit occupant's work load, improved the economy of aircraftPerformance.
Technical scheme of the present invention is:
There is an aircraft cockpit windscreen structure for sunshade ability, multiple transparent with conventional airplane driving cabinMaterial sandwich windscreen is basis, determines sunshade region, to fly according to aircraft cockpit design eye position 1The above windscreen of 1 apparent horizon region, machine driving cabin design eye position is sunshade region, in this region, and Jin LinfengOn the outer surface of the transparent sandwich 6 of the outer transparent ITO conductive heating film 2 of gear, be coated with the 2nd transparent ITOConductive heating film 3, and between 2 layers of ITO conductive heating film 2,3, insert transparent electrochromism sunshadeGlued membrane 4, under power on condition, forms certain electrical potential difference between 2 layers of ITO conductive heating film, makes transparentColor and the light transmittance of electrochromism sunshade glued membrane change, thereby realize blocking of aircraft cockpit windscreenFunction.
The coating face of the 2 layers of ITO conductive heating film 2 and 3 that preferably, arrange in driving cabin windscreen interlayerLong-pending different, wherein, outer ITO conductive heating film 2 is positioned at the inner side of the outer half tempered unorganic glass 5 of windscreenSurface is the plating of windscreen gross area; Internal layer the 2nd ITO conductive heating film 3 be positioned at the outer half tempered of windscreen withoutOn the outer surface of the windscreen transparent sandwich 6 that machine glass 5 is close to, and this plated film area and definite windscreen sunshadeRegion area is identical.
Preferably, transparent electrochromism sunshade glued membrane 4 is made for nanometer electrochromic material, is clipped in 2 layersBetween ITO conductive heating film 2 and 3, its area is identical with windscreen sunshade region area.
Preferably, the change color of the electrochromism sunshade glued membrane 4 adopting under power on condition should with drivingAlarm, caution light or the color of the aobvious control in cabin indication mechanism distinguish, and with driving cabin overall color environment faciesCoordinate.
Preferably, outer ITO conductive heating film 2 can be used for the anti-icing of driving cabin windscreen and removes under power on conditionMist;
Preferably, between 2 layers of ITO conductive heating film 2 and 3, apply the voltage of out of phase, can make electricityThere is reversible variation in the color and the light transmittance that cause variable color sunshade glued membrane 4, thereby realizes the screening of driving cabin windscreenSun function.
Advantage of the present invention is:
The sunshade function of aircraft cockpit unit is integrated among driving cabin windscreen structural design, has avoided biographyMechanical type solar protection devices is installed in the driving cabin of system, has been alleviated the weight of aircraft, improved the economy of aircraftCan; Sunshade function adopts automatically controlled, and windscreen color and light transmittance in sunshade region be reversible adjustable, justOperate in unit occupant; Sunshade windscreen can also play certain heat-blocking action.
Brief description of the drawings
