Cruise-Speed BVI Noise Computation by Comprehensive Code and Validation with HART I Data

van der Wall, Berend G. and Yin, Jianping (2009) Cruise-Speed BVI Noise Computation by Comprehensive Code and Validation with HART I Data. In: Proceedings, pp. 1-6. 2nd International Forum on Rotorcraft Multidisciplinary Technology, 2009-10-19 - 2009-10-20, Seoul, Korea.

In this paper DLR’s high resolution comprehensive rotor code S4 together with its prescribed wake module as well as DLR’s acoustic code APSIM will be used to simulate the aerodynamic loading (including blade-vortex interaction), blade motion, wake system (tip vortex helix and trajectory) and acoustic radiation of a 40% Mach-scaled Bo105 hingeless model rotor that has been used within the HART I test of 1994. The test cases used for code validation are the baseline case without active control (which represents a cruise-speed descent flight with strong blade vortex interaction noise radiation) and a case with 3/rev higher harmonic control applied to the blade root to minimize noise radiation.
