To investigate the influences of the fiber hygroscopicity on the pilot thermal responses, a heat and moisture transfer model for pilot/anti-G suit/environment system is developed. An improved Stolwijk model is used to simulate pilot thermal responses, and the coupled heat and moisture transfer model considering fiber hygroscopicity role is used for anti-G suit. The model is validated by literature experimental data. Then, effects of the fiber hygroscopicity on the pilot thermal stress index are analyzed by running the model program. Conclusion shows that the anti-G suit made of the fiber with high hygroscopicity can raise high thermal stress index of the pilot in high temperature and humidity environment.

“…The simulation program is written in FORTRAN. In order to validate the model, we simulated a process of an experiment in a hot climate chamber [1]. The chamber wind velocity is less than 0.1 m/s and the vertical and horizontal temperature difference is below 1 C. The dry temperature 40 C while the relative humidity is 54%.…”

“…To mitigate thermal stress of the pilot in various environments, research on thermal performance of anti-G garment is essential to provide critical information for improving the garment design. Qiu Yifen [1] developed a thermal performance analysis model of bladder anti-G garments based on thermal and moisture resistance model of the garment and human bio-heat transfer equations. However, the thermal resistance and moisture resistance are measured under steady-state conditions, which can't fully describe the real heat transfer process within the anti-G garments.…”

To investigate heat and moisture transfer mechanisms of the pilots anti-G suit with phase change materials and improve the thermal performance of the garment, a mathematical model for pilot-anti-G suit-environment system is developed. In the model, the coupled heat and moisture transfer and thermal regulation process of phase change materials (PCM) in the anti-G suit are considered, and an 85-node thermal regulatory model is used to simulate human thermal responses. The model is validated by literature experimental data. Then, the parameter effects of PCM on the thermal stress index of the pilot are analyzed based on orthogonal calculation method by utilizing the model. Conclusion shows that the more PCM content and higher latent heat become, the less thermal stress index is.
