Fitting large field of view optical pod structure and working method based on flat glass

Abstract

The invention relates to a large-view-field optical nacelle structure based on plain glass fitting and a working method of the large-view-field optical nacelle structure. The structure is characterized in that the large-view-field optical nacelle structure based on plain glass fitting comprises a nacelle and an optical photographing device arranged in the nacelle, a narrow strip-shaped visual window is formed in the end head of the nacelle, multiple sheets of a transparent material are sequentially spliced to form the narrow strip-shaped visual window, and the lens end of the optical photographing device directly faces the narrow strip-shaped visual window. By the adoption of the large-view-field optical nacelle structure based on plain glass fitting, performance uniformity and optical distribution evenness of a whole optical system in a whole view angle range can be achieved. The strength of a whole fairing is much larger than that of a semicircular fairing.

Description

Technical field: [0001] The invention relates to a flat glass-based fitting large-field optical pod structure and working method. Background technique: [0002] The pod refers to a streamlined nacelle section that is installed with certain airborne equipment or weapons and is hung under the fuselage or wing. It can be fixedly installed (such as an engine pod) or detachable (such as a weapon pod). The addition of pods can make the aircraft have functions that it does not have. The addition of pods usually requires the support of onboard electronic equipment and consideration of the overall aerodynamics of the aircraft. [0003] The common pod is installed under the belly of the aircraft, and is relatively large in size. In order to be able to resist factors such as wind and vibration, the pod is relatively large in size. The pod mainly includes an azimuth rotation part and a pitch rotation part. Because the azimuth and rotation axis of the pod is perpendicular to the belly ...

Problems solved by technology

However, the addition of a fairing not only protects the optical system, but also greatly restricts the forward field of view. The general field of view can only cover the range of -30° to 30° forward.
