  • New device for calibration of leakage rate of spacecraft

    Sep 20, 2020To solve this problem, a new type of leakage rate calibration device is designed and developed. The aim is to simulate as much as possible the actual working condition of the valve in orbit. The new device can be used to calibrate the leakage rate of the valve under high-and low-temperature environment and setting pressure.Author: D. Ding, L. Chen, D. Sun, L. Zhao, N. Wang
