Triebwerksintegration in neue Hochauftriebskonzepte Abschlussbericht HAK 1PP

Aim of the technology programme HAK1PP was, to complete the extensive investigations of HAK1/1P and HAK2 concerning the integration of Highbypass Engines in modern High Lift Concepts by essential aspects, on one hand by an investigation of jet induced secondary effects on the aerodynamics of a 4 engine configuration, on the other hand by flowfield measurements in the region of a VHBR engine close coupled to a high lift wing. So 2 TPS windtunnel campaigns were conducted in HAK1PP which concentrated on these items. TPS test in the DNW on a slightly modified A340 complete model with close coupled VHBR engines. In 5 high lift (Slat/Flap) configurations the TPS units were run alone and groupwise in a RPM range between through flow nacelle and maximum allowable RPM. The forces measurements were completed by parallel flow visualisation showing the separation behaviour of each configuration. The results as well as the following evaluation are presented in the report of part task 1. TPS test on a Megaliner-halfmodel in the Bremen Low Speed Wind Tunnel, where - using both a five hole probe and a 2D LDA - the velocity field was measured in the Fan jet and in the jet near region under the wing. A data set was created which will be used in the future to improve and validate numerical codes for the interaction between jet and wing flow. The results are presented in the report of this part task 2.
