Development of Aircraft Gas turbine Engine Design and Optimization Software Phase II

Kurzfassung

The aviation industry relies heavily on aircraft and engine performance for ensuring operational safety and efficiency. Analyzing and simulating aircraft and engine performance is crucial but challenging, requiring sophisticated tools. This project aims to develop a software capable of analyzing and simulating both aircraft and engine performance to determine the optimal engine for specific aircraft and missions, including a user-friendly software tool contributing to more efficient and effectiveness of engine operations. Leveraging insights from seminal works by Mattingly, Heiser, and Pratt, this project integrates principles and methodologies from aircraft engine design literature into software development. The developed software in this project is called “Aircraft Engine Analysis” or AEA software. The AEA software is capable of evaluating three engine types, consisting of a single-spool turbojet engine, dual-spool turbojet engine, and turbofan engine with mixed exhaust, considering factors like fuel consumption and thrust to aid users in informed engine selection, thereby maximizing aircraft efficiency. The AEA software's objectives include designing aircraft gas turbine engines from understanding aircraft design processes to engine design processes and providing a teaching and research tool. Our software encompasses aircraft constraint and mission analysis, parametric cycle analysis, and performance cycle analysis. The AEA software was validated against AEDsys, showing generally low error rates, indicating high accuracy and reliability. Specific analyses revealed some notable errors. Nevertheless, AEA consistently performed acceptably, confirming its robust simulation capability. Future refinements are needed to enhance accuracy and performance further.
