Sensitivity analysis of cockpit temperature control system of an advanced aircraft ECS

Cockpit temperature controlsystem requires maintaining the supply air temperature from the Air Cycle Machine (ACM) to havecomfortable condition inside the cockpit. The cockpit supply air temperature is influenced by many factors like bleed air flow & its rate of change, ambient condition and the attitude of the aircraft. In order to effectively design these sub systems, system simulation model has been created in AMESim. After validating the model for various static and dynamic cases in previous work, the model is then studied for sensitivity for various input and external factors. The results of the same are presented in this paper. From this analysis, the performance of ECS is studied and found that the system meets all the flight and environmental operating requirements.
