Single-point supporting flexible section for small-aperture reflecting mirror of space optical remote sensor

Abstract

The invention discloses a single-point supporting flexible section for a small-aperture reflecting mirror of a space optical remote sensor, which belongs to the field of mechanical supporting. The supporting flexible section comprises a supporting mandrel body, three radial unloading troughs formed on the supporting mandrel body, three circumferential unloading troughs, three pasteboards and three clearances formed on the supporting mandrel body, wherein the pasteboards are arranged between the radial unloading troughs and the clearances; and the circumferential unloading troughs are formed in the pasteboards. The single-point supporting flexible section has small size and the maximum diameter of the single-point supporting flexible section is smaller than one third of the aperture of the reflecting mirror, so the single-point supporting flexible section can be processed and assembled conveniently and flexibly, and the installation space is saved; the reflecting mirror in which the single-point supporting flexible section is taken as a key supporting part is high in temperature adaptability, so when the external thermal deformation is transferred to the reflecting mirror through a mandrel, the deformation can be absorbed by the unloading troughs formed in two directions, which is equivalent to the process for shielding the reflecting mirror, so that the reflecting mirror is protected; and when the bonding working procedure is performed, the deformation energy produced by an adhesive layer during the solidification can be absorbed by the unloading troughs in two directions, so that the reflecting mirror is protected.

Description

technical field [0001] The invention relates to the field of mechanical support, in particular to a single-point support flexible joint of a small-aperture reflector of a space optical remote sensor. Background technique [0002] In a space optical remote sensor, the size of the sub-mirror involved in imaging is often very small, and the secondary mirror is generally set at the highest end of the remote sensor, so the installation position and space are greatly limited, and because the remote sensor Due to the limitation of thermal control, the operating temperature of the secondary mirror always fluctuates within a wide range. Due to the influence of these factors, in order to ensure the imaging quality of the remote sensor, higher requirements are put forward for the supporting structure of the secondary mirror. At present, the commonly used support methods mainly include side support and mandrel rigid support. These two methods have great limitations, mainly reflected in...
