Abstract

This investigation aims to provide a validation framework for the dynamic simulation tool ASTOR (AircraftEngine Simulation for Transient Operation Research) for gas turbines. ASTOR is based on a system of ordinary equations which is able to simulate transient performance and dynamic response. The numerical setup of ASTOR is compared to state of the art transient performance simulation techniques for the validation. It is shown that ASTOR is able to calculate the performance of the single-spool turbojet engine under investigation to a level of detail that is in no way inferior than other approaches. Furthermore, an experimental validation is carried out using the in-house JetCat P200SX engine. Measurements of steady state operating points and transient maneuvers show a high degree of consistency with performance simulations conducted in ASTOR.
