Splicing type conformal optical window

Abstract

The invention provides a splicing type conformal optical window, and relates to the field of aeronautical facilities. The problems that by the existing optical window, only an optical load visual field angle in one direction can be expanded, and expansion of a large range of the visual field is limited are solved. The splicing type conformal optical window comprises seven pieces of flat-plate optical glass, wherein the seven pieces of flat-plate optical glass are glued together and mainly comprise a piece of main window glass, a first group of side glass, a second group of side glass and a third group of side glass; each group of side glass consists of two pieces of side glass with the same size and the same shape; sides of each two adjacent pieces of side glass are fixedly glued; and one sides of each group of side glass are fixedly glued with a corresponding side of the main window glass. On the premise that requirements of a main visual field of an inner effective load are met, the splicing type conformal optical window has enough strength and enough rigidity to resist influences of an external environment, and requirements of dynamics performance and invisibility of an aircraft can be met.

Description

technical field [0001] The invention relates to the field of aviation equipment, in particular to a spliced ​​conformal optical window. Background technique [0002] As an important part of the aerial remote sensor observation system, the optical window is an important unit of the optical payload imaging system. When the payload is working, the imaging light enters the optical system through the optical window and is imaged on the target surface. Since the optical window is directly exposed to the complex external environment, it is affected by factors such as external acceleration, pressure, and heat, resulting in deformation and temperature gradients, which are prone to wavefront distortion, which directly affects the imaging quality of the payload. In addition, most of the optical windows are directly connected with the aircraft as a whole, which will have a relatively large impact on the aerodynamic characteristics and stealth characteristics of the entire aircraft syst...
