Abstract

The invention provides a shock absorber for a large aviation optical nacelle and the aviation optical nacelle. The problem that an existing shock absorber cannot be applied to the large aviation optical nacelle is solved. The shock absorber comprises an inner mounting ring, an outer mounting ring and a buffer layer arranged between the inner mounting ring and the outer mounting ring, one end of the inner installation ring extends outwards in the axial direction to form a first installation face, and a plurality of first through holes are evenly distributed in the first installation face in thecircumferential direction. One end of the outer mounting ring reversely extends in the axial direction to form a second mounting surface, and a plurality of first threaded holes are uniformly distributed in the second mounting surface in the circumferential direction; the first installation face extends out of the buffer layer in the axial direction, and the second installation face reversely extends out of the buffer layer in the axial direction.

Description

technical field [0001] The invention belongs to a shock absorber on an optical load, in particular to a shock absorber for a large aviation optical pod and the aviation optical pod. Background technique [0002] Aeronautical airborne optical equipment is loaded on aviation aircraft to photograph air or ground targets, obtain target image information and spectral characteristic information, and the efficient acquisition of these information has a greater effect on scientific research and technical anti-counterfeiting. Research on optical devices is also a very important direction in the engineering field. [0003] Since the airborne optical equipment is loaded on the aircraft, the aircraft will have a relatively harsh vibration environment during take-off and flight. This vibration will adversely affect the imaging and measurement of the optical load in the airborne optical equipment. Vibration isolation or vibration reduction design measures are usually taken to reduce or e...
