Problems solved by technology

Due to the very large volume and weight of the primary mirror lens, its launch cost is very high
If the caliber continues to increase, in addition to the cost increase, its processing technology is also difficult to achieve

Embodiment 1

[0030] Such as figure 1 As shown, the edges of the reflective layer 2 and the transparent bottom layer 3 are pasted to form a side with a diameter of 2 mm; 2 is a reflective layer with a diameter of 0.5 meters, which is made of high-strength and flexible plastic, and can be blown in the mold first. Make a parabolic mirror with a focal length of 4 meters and a thickness of 1 mm. The inner surface of the concave surface is coated with a 0.5 micron gold film by chemical coating; made of plastic. The reflective film 2 and the bottom layer 3 are hermetically bonded on the supporting edge 1 . The whole inflatable reflector can be folded when the air pressure is low in the air bag, and when the air pressure in the air bag reaches a predetermined value, it will expand into a reflector. The experiment proves that the reflector can form an image when the ambient airflow and temperature are stable, and a good image can be obtained with the capture technology.

Embodiment 2

[0032] Such as figure 1 As shown, wherein 1 is a support edge made of high-strength nylon strips with a diameter of 3 mm. The reflective layer 2 has a diameter of 2 meters and is made of high-strength and flexible plastic. It is blown in a mold to form a paraboloid with a focal length of 25 meters and a thickness of 0.5 mm. The inner surface is coated with a layer of 0.5 microns by chemical coating method. aluminum film. The thickness of transparent bottom layer 3 is 3 millimeters, is made of transparent, flexible, foldable plastics. The entire inflatable reflector can be folded when the air pressure in the air bag is low, and expands into a reflector when the air pressure in the air bag reaches a predetermined pressure. The experiment proves that the reflector can form an image when the ambient airflow and temperature are stable, and a good image can be obtained with the capture technology.

Abstract

This invention discloses an inflation reflector for an outer space reflection type telescope, comprising a reflection layer and a bottom layer, wherein the reflection layer is a condenser, the concave surface of the condenser is coated with a light-reflecting layer, and the bottom layer is a transparent film. The edge of the reflection layer is adhered to the edge of the bottom layer to form an inflatable air bag, and the edge of the reflection layer or the edge of the bottom player is provided with an?inflation-and-deflation valve. The inflation reflector for the outer space reflection type telescope is foldable to obtain a relatively small volume which is beneficial for rocket emission. When reaching outer space, the internal of the inflation reflector is inflated and the air bag is expanded into a moon-shaped air bag to form the concave surface reflector for the outer space reflection type telescope. The inflation reflector for the outer space reflection type telescope is characterized by greatly reducing the volume and the weight of the telescope when the rocket is emitting and enabling the oversized outer space telescope to be possible.

Description

technical field [0001] The invention belongs to the technical field of astronomical telescope manufacture, and in particular relates to an inflatable reflector for a space reflective telescope. Background technique [0002] The primary mirror lenses of large astronomical telescopes are generally very large. For transmissive telescopes, the diameter of the single-mirror lens has reached more than 10 meters, and the total weight is dozens or even hundreds of tons. One with a diameter of 30-40 meters is also under construction. [0003] For reflecting telescopes, the light entering the telescope does not pass through the lens itself, so reflecting telescopes have no special requirements on the optical performance of the lens material, and can be made of light-weight materials, and because of the advantages of no chromatic aberration, so large Astronomical telescopes with large calibers mostly use reflective ones. [0004] However, the surface accuracy of a reflective objecti...
