Keywords: slender; asymmetrical control; pitching oscillation; detached-eddy simulation

DES is presented here to simulate the separated flow of the slender under the influence of pitching oscillation at high angle of attack. It is found the pitching oscillation at fixed frequency has strong control ability to the slender body, and the asymmetrical flow was restrained.
