| Abstract: |
| Objective To analyze on-orbit detection data of the space contamination detector for “TZ-1” Cargo Spaceship. Methods Quartz Crystal Microbalance (QCM) was used to detect contamination the TZ-1 to make use of the changes of oscillation frequency caused by contaminant deposited on the sensor crystal. The on-orbit contamination accumulation of the spacecraft was obtained by analyzing the downloaded original data based on the detecting principle. Results The detection data showed that optical properties of contamination sensitive components deteriorated significantly udder the influence of accumulation of contaminants. The contamination source temperature was an important influencing factor of contamination accumulation. Consequently, temperature could be taken as an important method for on-orbit contamination control on spacecraft. Conclusion These results can be references for contamination control design, and also provide data support for improving spacecrafts reliability. |
