  4. Abstract:
  5. Wing rock can be described as an oscillatory bank angle buildup to a constant amplitude rocking motion. This phenomenon is realized for delta wings with more than 74 degrees leading edge sweep angles where asymmetric vortex shedding occurs before vortex breakdown. For wings with sweep angles less than 74 degrees, rocking motion occurs if the wing is in a yawed situation. In this paper, a new and simple method has been presented to predict the amplitude and frequency of oscillation of delta wings undergoing rocking motion at high angles of attack. The pfeedicted data are in excellent agreement with -those obtained by experimental studies for wings with sweep angles of 76 and 80 degrees. © 2002 by M.R. Soltani, S.A. Ebrahimi and A.R. Davari
