Effect of Forebody Strakes on Wing Rock Motion on a Generic Wing-Body Configuration Having Chine Forebody

Abstract:

Experimental investigations are carried out to study the effect of forebody strakes on the wing rock motion of wing-body configuration. The cross section of forebody is of a chine shape. The chine shaped forebodies have advantage over slender nose forebodies as they generate more lift due to stronger forebody vortex. At higher angle of attack, the vortex asymmetry and asymmetric break-down can lead to un-commanded motions like roll divergence, wing rock etc. Of the two strake configuration studied, one configuration has exhibited the potential to delay and suppress the onset of wing rock, thus enhancing the angle-of-attack range where, no observation of un-commanded lateral motions is observed.
