Fig. 1 represents to be bonded in side by side no supercharging aircraft, as autogyro, the upright member on the preceding window frame structure of frame-use substantially (3) expression-on two blocks of luffer boards, this two boards is used (1 and 2) expression substantially.Each piece luffer boards can be flat, also can be curve, to meet the design of aircraft.
Each piece luffer boards comprises that one contains the interlayer of glass outer layer (4), and in this embodiment, glass outer layer thickness is 2.5 millimeters, and there is a conventional type resistance heat film (5) on the surface within it.
Cleaved glass is bonded on the inner polycarbonate layer of 6 millimeters thick with the polyurethane interlayer (7) of 2.5 millimeters thick.Inner polycarbonate layer (6) has self-heating polyurethane external coating (8), this layer is used as anti-abrasion coating, and can be the sort of anti-wear polyurethane of describing among 2011 836A of British patent (GB) or 2070 045A of British patent (GB) for example.
The one viscosity astragal that is bonded on the polyurethane coat side (8) of layer of polycarbonate (6) is being arranged around the inside face of poly-carbon ester layer (6) band coating, and this has the adhesive surface (9) of a bonding window frame (3).
The viscosity astragal is transparent, the thermoset polyurethane wall (10) that comprises 4 millimeters thick is bonded in flat electric heating element (11) with the first thermoplastic polyurethane bonding coat (12) of 0.5 millimeters thick the one side of this wall (10).The second thermoplastic polyurethane bonding coat (13) of 0.5 millimeters thick identical with layer (12) is bonded in the another side of wall (10) on the polyurethane layer (8) on the inner polycarbonate layer (6) of luffer boards.Than the 3rd low thermoplastic polyurethane layer (14) of polyurethane bonding coat (12 and 13) sinter point, thickness is 1 millimeter, be bonded on first bonding coat (12) and the heater element (11), in fact this heater element is placed in the trimerization urethane (14), and this layer provides adhesive surface (9) for bonding window frame.
Bonding coat (12 and 13) can be that ((K.J Quinn Gompany Inc.) has thermoplastic polyurethane can be purchased off the shelf to the K.J. Quinn Co., Ltd of U.S. Ma Saxusai state Ma Erdeng (Molden) to themoplasticity PN03 polyurethane material.）。
When production viscosity astragal, electric heating element (11) is placed on the outside face of layer (12), crenelated two copper sheets of representing among form such as Fig. 2.The skin (14) that heater element (11) are housed is the polyurethane material of thermoplastic polyether (polyethe-) or polyester (polyester-) base, its sinter point is between 70 ℃ to 120 ℃, this sinter point is lower than the sinter point of bonding coat (12 and 13) material, and just can fully soften about 105 ℃ with bonding or disengaging airframe member (3).
Electric heating element (11) is fixed in the viscosity astragal so just asymmetricly, and is nearer apart from luffer boards polycarbonate plate (6) apart from exposure adhesive surface (9) ratio of adhesive tape.
Adhesive tape is just round the inside circumference of luffer boards.In place, the end of heater element layer (11) is connected with power connection, and power supply provides heating current.
The airframe window frame structure, wherein a member can be the reinforcing fiber material with (3) expression, when when heater mat (11) provides heating current soften layer (14), polyurethane layer (14) is easy to be bonded on this reinforcing fiber material.
Made dirty with in avoiding storing and installing can using a kind of temporary protection layer on the adhesive surface (9) of layer (14).Before use, remove this protective cover again.
As shown in Figure 1, in the autogyro wind shelves of reality, two blocks of such plates are installed side by side, and the centre has the gap of one 4 mm wides that its limit is separated, and copper silicon (Silicone) filler (15) are housed so that embedded wind shelves to be provided in this gap.
The viscosity astragal is transparent, so in use, when heater element heats this band, can see through luffer boards and observe layer (14) and be installed in wet degree on the airframe window frame structure.
When the autogyro glass port was installed, suggestion luffer boards internal surface temperature did not raise significantly.Although the heat of the softening polyurethane layer (14) of the electric heating element in the adhesive tape (11) is enough to guarantee and can be bonded on the aircraft body structure.
This structure has a thermal insulation layer between heater element (11) and cated inner polycarbonate layer (6), this layer mainly is that the thermoset polyurethane wall (10) by adequate thickness provides.This has just guaranteed that bonding coat (14) is softened before coating (8) or layer of polycarbonate (6) heat significantly, and luffer boards are bonded on the window frame.
In the process that glass is installed, the layer (14) thus the softening buffer action that plays guarantee in installation process when when the luffer boards outside face applies uniform positive pressure, the uniform contact of viscosity astragal and window frame structure (3), and most of viscosity astragal is still enough hard to transmit clamping force.After heating power supply is turned off, on luffer boards, still keep this pressure up to layer (14) hardening, till luffer boards are bonded on the airframe really.
In the time will removing the luffer boards of damage, heater element (11) is connected heating power supply, at first soften layer (14).The luffer boards that damage just can be taken away, and take away most viscosity astragals, needn't add cleaning to window frame when new luffer boards are installed.This possibility that is adhered on the airframe and is separated from airframe does not influence bonding mutually between the element of forming adhesive tape, does not influence the inside face that adhesive tape is adhered to the interlayer luffer boards yet, does not influence the structure of sandwich plate itself yet.
The luffer boards visual field that embeds airframe is fine, and this glued construction can bear the distortion and the hotness stress of airframe, and both of these case occurs when autogyro or aviette flight especially easily.
Another structure of the present invention as shown in Figure 3.The internal layer of luffer boards (6) is acrylate (acryltc) layer that stretches.When temperature began a little higher than 100 ℃, the acrylate material just damaged, and this is because the acrylate layer that stretches just reinstatement when temperature surpasses 104 ℃.In this embodiment, the layer of viscosity astragal (13) directly is bonded on the exposure of acrylate internal layer (6), between heater element (11) and acrylate layer (6) by astragal the layer (10,12 and 13) thermal insulation layer that provides can not raise significantly with the inside face heating-up temperature that guarantees acrylate layer (6) in the luffer boards process is installed.
