Wallace D. Hayes (b. September 4, 1918 – d. March 2, 2001) was a professor of mechanical and aerospace engineering at Princeton University and one of the world's leading theoretical aerodynamicists, whose numerous and fundamental contributions to the theories of supersonic and hypersonic flow and wave motion strongly influenced the design of aircraft at supersonic speeds and missiles at hypersonic speeds.This greatly enhanced the development of supersonic flight and supersonic aircraft design.
