In this paper the solution of thin airfoils problem in nonequilibrium ideal fluids is given. No use of the distribution theory as in Homentcovschi solution [1] is done. In the frozen subsonic case the boundary value problem is reduced to the integral equation (12) which is asymptotically integrated for τ ≫ 1. In the frozen supersonic case the boundary value problem is reduced to the integral equation (25) which is solved exactly. The solution for the motion in the presence of an infinite wall is given too .
