Mounting flange structure and preparation method of spherical pressure vessel installed at equator

Abstract

The invention discloses an equator installation spherical pressure container mounting flange structure and a preparation method thereof. The flange structure comprises a lower flange, an upper flange and a composite material layer; the lower flange is connected with the upper flange; and the composite material layer is wound on the outer surface of the lower flange and the outer surface of the upper flange. The method comprises the following steps: (1) the upper flange and the lower flange are prepared; and (2) the upper flange and the lower flange are assembled through two annular groove structures on the upper flange and the lower flange. The equator installation spherical pressure container mounting flange structure solves the mounting mode limitation problem of a composite material pressure container, and has such advantages as high adaptability and light mass.

Description

technical field [0001] The invention relates to a mounting flange structure and a preparation method thereof, in particular to an equator-mounted spherical pressure vessel mounting flange structure and a preparation method thereof. Background technique [0002] At present, spacecraft propellant management devices are generally spherical structures. Since the equatorial flange installation method has good mechanical environment resistance performance, all-metal pressure vessels are generally installed with equatorial flanges. Due to the special requirements of the winding process, the composite material pressure vessel has high requirements on the appearance of the pressure vessel before winding, and the equator of the storage tank is not allowed to have flanges. If the flange structure is used, the flange and Composite tanks. At present, there is no composite material winding pressure vessel in the country that adopts the flange installation form, and generally adopts band ...

Problems solved by technology

There is almost no column section at the equator of the spherical composite pressure vessel, so the installation method of the Alphabus satellite platform cannot be used

[0003] Composite pressure vessels have gradually become the key components of aerospace power systems. However, with the continuous requirements of the new generation of aerospace vehicle power systems for lightweight, compact, and strong adaptability to mechanical environments, composite pressure vessels are connected by straps and The way of fixing both ends can no longer meet the requirements of the system for the general assembly layout and the adaptability of the mechanical environment, and has become one of the bottlenecks in the development and development of aerospace power systems

The existing installation methods of spherical composite pressure vessels are limited to band installation and installation at both ends, and equatorial flange installation cannot be realized
