Application of MATLAB-Based Automated Turbine Engine Analysis

摘要

The flight testing of propulsion systems has always centered on engine response and operability. The flight testing and evaluation process can be data intensive due to the sophistication of the hardware and software and the fact that response and operability needs to be verified throughout the entire aircraft flight envelope. This is true whether the item under test is a new engine or a modification of an existing engine. The analysis of engine operability has traditionally been a manually intensive process. Determination of when a critical event occurred (e.g., combustor light-off or engine stability) can vary from engineer to engineer. The variance can be attributed to the fact that critical events are not always clear and at times depend on a 'judgment call' by the engineer doing the analysis. This paper will present the automated analysis of engine airstarts and throttle transients. This analysis was performed using a MATLAB-based analysis and plotting software tool developed at the Air Force Fight Test Center (AFFTC), Edwards AFB, California. The program was called the Airstart and Transient Analysis Program (AirTrans AP).
