Abstract

During ground-based thermal vacuum tests of spacecraft, it is necessary to control and monitor the change in dust content in closed and semiclosed hollows of the spacecraft, near the optical surfaces of scientific and service hardware, mirrors, solar arrays, multilayer insulation, as well as in the volume of the thermal-vacuum chamber itself during its evacuation etc. It is known that the scientific reliability and significance of the results from instruments in space to ground-based research centers are greatly affected by dusty optics. The article provides a description of a new method for automated dust control of the external atmosphere of a spacecraft and its modules during thermal vacuum tests. A patent has been issued for this method; the patent holder is the Russian Federation, on behalf of which the State Space Corporation Roscosmos acts (RU). In addition to the rocket and space and aviation industries, this method can be used in electronic and microelectronic technology, nuclear technology, medicine, the food industry, etc.

真空试验中航天器外部大气自动除尘的新方法

摘要

在航天器的地面热真空测试期间，有必要控制和监视航天器的封闭和半封闭凹坑中粉尘含量的变化，这些变化在科学和服务硬件，镜子，太阳能电池板，多层绝缘等光学表面附近，例如众所周知，尘土光学系统极大地影响了从太空中的仪器到地面研究中心的结果的科学可靠性和意义。本文介绍了一种在热真空测试过程中自动控制航天器及其模块外部大气粉尘的新方法。该方法已获得专利。专利持有人是俄罗斯联邦，Roscosmos国家太空公司（RU）代表的行动。除火箭，航天和航空工业外，此方法还可用于电子和微电子技术，核技术，医药，食品工业等。
