A Sensor for the Spatial Registration and Measurement of Particles Parameters in Near and Deep Space-Experimental Investigation of SiO_2-Aerogel Characteristics

摘要

The paper describes a new sensor for the spatial registration and measurement of particle parameters in near and deep space. The following modern materials are applied in the sensor structure: a PVDF piezoactive film and lightweight heat-shielding high-temperature aerogel. The results from studying the aerogel morphology as well as its thermal conductivity depending on the air temperature are presented. The thermal conductivity of a SiO_2-aerogel is compared with one of foreign aerogels and air. Its elemental quantitative chemical composition is determined.
