specific Embodiment approach 1

[0039] Specific embodiment one: a kind of multilateral bucket of this embodiment, the ladle body of this multilateral bucket 2, bucket bottom, bung 20 cross-sections are polygonal; There is a filler 3 between the outer barrels 1, and the filler 3 is solid.

[0040] The bottom of the outer bucket adopts a hemispherical bucket bottom 10 filled with liquid or solid matter 21 .

specific Embodiment approach 2

[0041] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the polygonal barrel is provided with piston 8, there is liquid 6 between the bottom of the barrel of the multilateral barrel 2 and the piston 8, there is pipeline at the bottom of the barrel of the multilateral barrel 2, can The liquid 6 between the piston and the bottom of the barrel flows out. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0042] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the polygonal bucket has a thermal insulation layer. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a polygonal barrel and a protective device for a space telescope lens, and provides a liquid filling barrel. At present, the overload of a rocket is 3-4G during launch, and thecurrent lens of a space telescope is thicker and higher in strength due to the limitation of the overload during the launch. The lens of the telescope is placed in the liquid filling barrel, and it is ensured that the lens is not affected by the overload and not deformed by using liquid and acceleration inversion hydraulic pressure borne by the barrel. By adopting the polygonal barrel and the protective device for the space telescope lens, a space transfer line system can be accessed when the lens is launched, so that the cost of the launch is reduced. The overall quality of the telescope ismuch less, and it is much easier to adjust the posture in space.

Description

technical field [0001] The invention relates to a protective device for a lens of a space telescope, in particular to a polygonal barrel and a protective device for a lens of a space telescope. Background technique [0002] At present, the overload during rocket launch is 3-7G. In order to avoid overload during launch and prevent the lens from being deformed due to the pressure caused by acceleration during launch, the space telescope can only thicken the lens or add ribs, and a bracket must be added during launch to keep the shape unchanged. The bracket is thick, the overall quality is large, and the cost is high. [0003] The front face of the lens can be fabricated with an accuracy of 100 nanometers. The lens finish is very high, and the cleaning process is cumbersome. The back of the lens is ribbed. [0004] The light-gathering area of ​​the Webb Space Telescope is 25m 2 , the mass of the lens per square meter is more than 15kg, and a complex bracket is required to ...
