SIDEWASH ON THE VERTICAL TAIL IN SUBSONIC AND SUPERSONIC FLOWS

A generalized vortex-lattice method is used for the investigation of s idewash on the single and twin vertical tails due to rolling wing in s ubsonic and supersonic flows. The current results of sidewash on the s ingle vertical tail in incompressible inviscid now are almost the same as Michael's calculations. The sidewash on the single vertical tail t hrough high angle of attack is presented. The difference of sidewash o n the single and twin vertical tail that is induced by the rolling win g in subsonic and supersonic flows is also studied.
