SNGR BASED FAST ANALYSIS OF SLAT TRACK NOISE SOURCES
W.H. Wang, China; Q.C. Wang, China; C. Breard, China; Y.F. Sun, China
SNGR based fast analysis are conducted to evaluate the broadband noise source. The strongest noise source of the slat locates at the impingement point of shear flow on the downstream cove surface. The track brings new strong noise source above the track root and the main wing leading edge. The cavity further introduces large scale strong noise source in the separation zone above the cavity.
