Abstract
The invention relates to a main windshield assembly for airplanes and an installation method thereof. The main windshield assembly comprises windshields, a pressure plate, skylight frameworks and a connecting piece, wherein the windshields are fixed between the pressure plate and the skylight frameworks through the connecting piece and are shaped as a curved surface. The main windshield assembly provided by the invention has a good field of view, driving cabin space and pneumatic property, good bird strike resistant performance, and a more open channel for driver emergency evacuation; in addition, by the adoption of the installation method, the fatigue life of the main windshield assembly is greatly raised and the main windshields can be rapidly assembled and repaired.
Description
Technical field
The present invention relates to be used for the main air retaining assembly set and the installation method thereof of aircraft.
Background technology
The aircraft windshield is a structural features important on the aircraft.As the part of fuselage, windshield wants to bear structural load and the impact under the various state of flights; Simultaneously, windshield will provide visual field and good optical performance clearly for chaufeur, also will possess the deicing demist, lets out static, anti-rainwater etc. is all multi-functional.Requirement on structure and function contradiction often concerning material, windshield technology are exactly to satisfy the specific (special) requirements of the performance such as various mechanics, optics, electricity, environment of aircraft by the research of aspects such as material selection, structure design, manufacturing process, test evaluation simultaneously.
Although the windscreen of aspect helps thickening thickness of glass, can strengthen the structural load of bearing under the various state of flights and the performance of impact, and the plane curvature tolerance is good, this kind windscreen has a strong impact on aviator's field range.
In the windscreen assembling unit structure that has proposed at present, publication number be US 2003/0062450A1 U.S. Patent Publication the one chip flange design of windshield annex, windscreen is clamped in the groove of window frame structure by the one chip flange.In the outside of one chip flange, the windscreen pressing plate is installed again.The mounting means of this windscreen, complex structure, the loading transfer of bearing on the windscreen is not direct to the route of peripheral window frame structure yet.
Publication number is that the Chinese patent application of CN 101473143 discloses a kind of being used for being inserted in the nut that two aircraft windshields between the holding element are fixed, and described holding element is assembled by at least one link that is made of bolt and described nut and remained to together; Described nut is made of two parts.When nut damages, especially when changing windshield, can change described nut easily.But it also is aspect that windshield is adopted in this patent application.
Summary of the invention
The objective of the invention is to overcome existing above-mentioned shortcoming in the existing design.
According to an exemplary embodiment of the present invention, main air retaining assembly set comprises windscreen, pressing plate, skylight skeleton and attaching parts, and wherein windscreen is fixed between pressing plate and the skylight skeleton by attaching parts, and windscreen adopts the curved-surface structure form.Be preferably the single-curvature surface shape.The for example monolateral transparent region area of main air retaining is approximately 0.5m
2Thereby, with respect to the plane windscreen visual field, driving compartment space and aerodynamic characteristic preferably being arranged, anti-preferably bird is hit performance, and driver emergency is withdrawn passage and is more opened wide.
Windscreen is fixed between pressing plate and the skylight skeleton by attaching parts, and the presser type mounting means that adopts tripartite pressing plate, a side to insert can carry out the assembling and the maintenance of main air retaining fast.Because participation structure is not stressed for the windscreen of presser type mounting means, improve the fatigue life of windscreen greatly.In addition, the main air retaining adopts presser type to install with convenient outside dismounting and maintenance, and is convenient and swift.And the main air of presser type mounting means keeps off that participation structure is not stressed, and with respect to the Transparent Parts of the bonded assembly windscreen that directly is spirally connected, improve its fatigue life greatly.
The presser type of curved wind screen is installed, and makes the design of structure-skylight skeleton of windscreen periphery have more challenge.Main air retaining Transparent Parts bottom all has skeleton to support preferably, so the main air retaining is when bearing bird and hit impact load, and Transparent Parts can be delivered to load on the skeleton rapidly, thereby the anti-bird of improving Transparent Parts is hit ability.
Advantageously, skylight skeleton itself needs also to consider that bird hits factor, and skeleton each cross-sectional plane in skylight all has the higher bending resistance height and the interior edge strip of broad, in the time of bearing bird preferably and hit moment very big moment of flexure.
Advantageously, the skylight skeleton adopts dispersion to cross with canopy top plate, sidewall paneling, the isostructural connection of each associated frame, avoids too much rib to concentrate junction, to improve each part stress situation.The top of skylight skeleton is set up by the antitorque camber beam of glass frame upper limb and is added the keystone configuration form that the radial pattern skeleton is the master, the bottom is supported on each close frame by the many fulcrum hinge joints of window frame lower edge beam, formation is based on many point supportings structure of close frame, and downward, back kick increases progressively compressive load.
Advantageously, skylight skeleton area arrangements more reinforcement backing plate be connected with surrounding covering, can pass better and carry, improve the stand under load situation of whole regional structure greatly.
Advantageously, the material of skylight skeleton part itself, in-to-in attaching parts and with the attaching parts of pressing plate, all adopt non-magnetic material, therefore, guarantee the serviceability of equipment such as standby magnetic compass.
Such structure design has guaranteed that the presser type installation of large tracts of land curved surface main air retaining is achieved.
