Abstract
Simulations of a complete air vehicle including all the various subsystems such as the environmental control, air vehicle, and power/thermal management subsystems have been utilized on a mission level. Relatively few attempts have been made to define appropriate validation testing constructs for this analysis in a transient mode of operation. Current research addresses the process of validation testing using legacy aircraft systems in order to acquire relevant data that will lead to the validation of existing models, and different modeling methods. In order to aid in this effort, a tip-to-tail (T2T) model of a legacy aircraft is being created. This effort has two major challenges integrating more realistic subsystem models that are representative of the actual system. To this effect, an air vehicle system (AVS), engine, generator, and environmental control system (ECS) models have been generated to model the actual legacy system. In particular, this research will focus on the creation and integration of the generator and ECS model. The ECS uses an air cycle machine which utilizes a Brayton refrigeration cycle to cool the air to the cockpit and avionics. The generator model uses both electrical and thermal models to calculate the power and heat generated which connects to the rest of the model. These models will lay the foundation for more validation work on the T2T models.
