Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] see Figures 1 to 4 , what is shown in the figure is a surface conformal method for aircraft formation lights, and the following steps are performed in sequence,

[0037] Step S1, providing formation lamp bodies 1 .

[0038] The formation lamp body 1 includes a lamp body shell and a curved surface light source 14 .

[0039] The lamp body shell has a panel 11 , a middle panel 12 and a bottom panel 13 which are sequentially arranged from top to bottom. The face plate 11, the middle plate 12 and the bottom plate 13 are respectively made of glass fiber reinforced polycarbonate plates of corresponding thickness. The final quality of surface forming is closely related to the thickness, thickness ratio and material selection of each plate. In this embodiment, the thicknesses of the panel 11, the middle plate 12, and the bottom plate 13 are 1mm, 2m...

Abstract

The invention relates to a conformal method of curved surfaces of aircraft formation lights. The conformal method sequentially comprises the steps of S1, providing formation light bodies; S2, carrying out heating treatment; S3, stopping heating; S4, carrying out negative pressure formation; S5, carrying out cooling treatment; S6, carrying out post forming machining. The conformal method has the advantages that interlayer bonding is unstressed, the curved surfaces are accurately formed, surface light sources are high in luminance uniformity, and the shock resistance and the temperature impact resistance of the formation lights can be obviously improved.

Description

technical field [0001] The invention relates to a formation light on an aircraft, in particular to a curved surface conformal method for an aircraft formation light. Background technique [0002] With the rapid development of my country's military industry, the types and quantities of military aircraft are constantly increasing. Almost all military aircraft, especially fighters and bombers, pay great attention to formation flying. Airborne formation lights are one of the effective safety devices to ensure the formation flight of the fleet and covert approach to the target. [0003] At present, the vast majority of airborne formation lights in this industry use EL surface light sources embedded in the laminated bonded structure of epoxy glass cloth boards. Due to the poor high temperature resistance of the EL light source material (≤70°C), and the epoxy glass cloth board is a thermosetting material, it cannot be secondary molded. Therefore, the surface conformality can onl...
