DESIGN OF AN ULTRA-HIGH BYPASS RATIO FAN STAGE FOR A RESEARCH TURBOJET ENGINE
Abstract
At the Department of Aeronautics, Naval Architecture and Railway Vehicles of Budapest University of Technology and Economics there is a versatile micro turbojet test bench based on TS-21 turbostarter engine. Besides research and developement purposes it offers a more practical study and experience for the aerospace engineering students. In this study the authors have accomplished a theoretical design of an additional fan stage to the original TS-21 engine. Based on the results of this study a decision can be made, whether the modification of the present device is worth or not. For supplementing this decision, a complex feasability study was carried out from a simple one-dimensional flow analysis through computational fluid dynamics and stress analysis of the mechanical parts. If the designed equipment will be manufactured, the resulting turbofan engine can be used to model large scale types for various research and educational purposes.
