Simulation and verification of bleed system of a civil aircraft simulator

Abstract

With the increase of aircraft complexity and development of simulator technology, aircraft simulators are more and more important. At the same time, the simulation fidelity and complexity of the simulator is higher. Therefore, it is very difficult and expensive to improve and enhance the correctness and fidelity of simulator simulation model mainly based on test data. So this paper proposes to use the process assurance method for aircraft complex system and product in order to establishing simulator simulation model. Based on analysis of simulator simulation model needs, from top to bottom, the simulation requirements is captured based on operation scenarios, and then bleed system model is established based on symbol library and modular. For simulator simulation model verification, the bottom-up verification method is used to simulation model verification. Those methods are used to ensure the correctness and fidelity of the simulation model.
