One example is the use of advanced transonic airfoils that in the ’60s and early ’70s were developed in the wind tunnel. Today they are designed reliably using 2D computational codes such as GRUMFOIL Another example is the incorporation of the SC concept in a highly swept fighter design requiring efficient supersonic maneuvering. uction“Usersshouldapproachallsoftwarewithprudentcautionandhealthyskepticismforthehistoryofscienceandengineeringincludingthestill.
