Description
技术领域technical field
本发明涉及热控多层包覆技术，尤其涉及一种感应式磁力仪进行热控多层包覆的方法。The invention relates to thermal control multi-layer coating technology, in particular to a method for thermal control multi-layer coating of an induction magnetometer.
背景技术Background technique
感应式磁力仪是由三个相互垂直的磁天线(感应式线圈)组成，用来测量某一频段范围的内变化的磁场信息。由于太空的轨道热环境较为恶劣，当其在太空轨道环境工作时，为了保障其工作性能，需要进行良好的热防护。The induction magnetometer is composed of three mutually perpendicular magnetic antennas (induction coils), which are used to measure the changing magnetic field information within a certain frequency range. Due to the harsh orbital thermal environment in space, when it works in the space orbital environment, in order to ensure its working performance, good thermal protection is required.
目前常用的太空轨道热防护方式是采用多层隔热材料对需要热防护的产品进行多层隔热包膜。现有的包膜方法主要是在平面或圆柱面等规则的几何面上，依托产品本身具有的构型进行贴身包膜；采用强力胶在产品和多层包膜上分别粘贴尼龙搭扣，通过尼龙搭扣将多层包膜固定在产品上；相邻两块多层之间并通过交叉搭接的方式进行连接，以防止两块多层连接部分的漏热。At present, the commonly used heat protection method for space orbit is to use multi-layer heat insulation material to carry out multi-layer heat insulation coating for products that need heat protection. The existing coating method is mainly on the regular geometric surface such as plane or cylindrical surface, relying on the configuration of the product itself to carry out the close-fitting coating; using super glue to paste Velcro on the product and the multi-layer coating respectively, through Velcro fastens the multi-layer coating on the product; two adjacent multi-layers are connected by cross-lap joints to prevent heat leakage from the connecting parts of the two multi-layers.
对于感应式磁力仪这一类特殊产品，其多层包膜的方法尚不成熟，存在以下问题：For special products such as inductive magnetometers, the multi-layer coating method is still immature, and there are the following problems:
(1)无法满足隔热要求，感应式磁力仪工作时需要温度波动尽量小，由于其树状构型的结构形式且尺寸较小，如果采用现有的包膜方法，依托产品现有的树状构型进行紧身包覆，既无法在产品上采用强力胶粘贴尼龙搭扣对多层包膜进行固定，也无法对相邻多层进行交叉搭接，存在漏热的问题。(1) It cannot meet the heat insulation requirements. The temperature fluctuation of the induction magnetometer needs to be as small as possible when it is working. Due to its tree-like structure and small size, if the existing coating method is used, relying on the existing tree of the product It is not possible to use strong glue to stick Velcro to fix the multi-layer coating on the product, nor can it cross-bond adjacent multi-layers, and there is a problem of heat leakage.
(2)无法满足绝缘要求，感应式磁力仪的工作原理要求在每个磁天线外部不得存在360°的周向导电回路。多层包膜本身是由双面镀铝聚酯薄膜和涤纶网组成；由于镀铝膜的存在，现有的贴身缠绕的包膜方法，会在每个磁天线外部形成360°的周向导电回路，影响感应式磁力仪的工作性能。(2) The insulation requirements cannot be met. The working principle of the inductive magnetometer requires that no 360° circumferential conductive loop should exist outside each magnetic antenna. The multi-layer coating itself is composed of double-sided aluminum-coated polyester film and polyester mesh; due to the existence of the aluminum-coated film, the existing wrapping method of wrapping next to the body will form a 360° circumferential conductive pattern outside each magnetic antenna. The loop affects the working performance of the induction magnetometer.
(3)无法满足等电位要求，感应式磁力仪在工作时需要外部多层包膜的任意两点之间的电位差小于1V。当感应式磁力仪在轨道空间运行时，多层包膜的外表面会暴露在等离子体环境中，空间带电粒子将在包膜表面材料沉积产生电位，由于材料阻抗及绝缘要求，采用现有的多层包膜方式必然会产生无法满足等电位要求的的情况。(3) The equipotential requirements cannot be met, and the inductive magnetometer needs the potential difference between any two points of the external multilayer coating to be less than 1V during operation. When the inductive magnetometer is running in the orbital space, the outer surface of the multilayer coating will be exposed to the plasma environment, and the space charged particles will deposit on the surface of the coating to generate a potential. Due to the material impedance and insulation requirements, the existing The multi-layer coating method will inevitably produce situations that cannot meet the equipotential requirements.
