空间用多层绝热组件隔热特性的试验研究
Experimental Study of Heat Insulation Capability of MLI Assembly in Space
摘要
多层绝热组件在高真空环境下具有超强的隔热性能,其优异的隔绝热辐射和热传导能力对红外光电设备可以起到高效的热保护作用,因此在航空航天上有着极其广泛的应用。主要测试了航天用双面镀铝聚酯薄膜多层绝热组件在高真空环境下的传热性能,为工程应用提供了具体的数据。
Abstract
Multi-layer Insulation (MLI) assemblies have excellent thermal insulation performance in high vacuum environment. Their excellent heat radiation and heat conduction insulation ability can provide an effective thermal protection for infrared opto-electronic equipment. So, they have extremely wide applications in aerospace. The insulation performance of a MLI assembly for space application with duplex aluminized polyester film is mainly tested in the high vacuum environment. The test has provided specific data for an engineering application.
