Development of Intake Swirl Generators for Turbo Jet Engine Testing
Abstract
The main objective of this investigation is to assess the influence of different types and magnitudes of swirl on the performance and compatibility of turbojet engines. The generation of intake swirl, typical for many supersonic combat aircraft, is described. Essentially two basic types, i.e. twin swirl and bulk swirl of varying strength and also combinations thereof, have been selected in order to simulate these swirl patterns by subscale swirl generators in a model wind tunnel. The swirl patterns measured behind these generators show good agreement with the target patterns selected at the beginning. The small scale swirl generators are being rebuilt at full scale for subsequent testing in front of a Larzac engine under static conditions with a bellmouth inlet at the engine test facility of the Jet Propulsion Instituet at the Universitaet der Dundeswehr Muenchen.
