基于泵变频调速的航天器热控制技术
Spacecraft Thermal Control Technology Based on Variable Frequency Pump
摘要
Abstract
The traditional temperature control mode using temperature-sensing valve has three deficiencies with the reliability, dynamic behavior, pump operational efficiency. In order to solve these problems, a new thermal control technology based on variable frequency pump was put forward for a fluid loop prototype model. The temperature control performance of the thermal control technology based on variable frequency pump was tested. During all transients, the controlled temperature was within the range of ±0. 3℃ around the set-point, with a maximum admissible variation range of ±0.5℃. Thermal control strategy based on variable frequency pump has effective performance.关键词
