The thermal comfort of the fighter cockpit environment is an important factor to ensure the pilot man-machine efficiency and the best combat performance of the fighter. However， the commonly used PMV-PPD human thermal comfort evaluation index cannot be applied to the extremely uneven flow field and temperature field environment in the cockpit， and the thermal comfort of the cockpit environment lacks effective optimization design means. This study first uses STAR-CCM+ and TAITherm software to realize the joint simulation function of air distribution in the cockpit， Fiala human physiological model and Berkeley thermal comfort evaluation model， and then optimizes the human thermal comfort and temperature non-uniformity coefficient. Genetic Algorithm （GA） is used to optimize the flow distribution of multiple air outlets in the cockpit. Compared with the traditional decoupling method， the joint simulation method can effectively improve the calculation accuracy of the skin temperature and thermal comfort of the pilot in the cockpit. Compared with the initial design plan， the temperature non-uniformity coefficient around the human body has improved by 16% after optimization， and the overall thermal comfort has increased by 0.285， accounting for 14% of the quantization scale ladder. Meanwhile， most of the local thermal sensation and thermal comfort of the optimization plan have been improved to varying degrees. Among them， those of the head and neck has improved the most， with the thermal sensation and thermal comfort of the neck increased by 0.55 and 0.781， respectively， accounting for 55% and 39% of the quantization scale ladder， respectively.
