Abstract : When boundary layers transition, whether or not one has the appearance of induced normal aerodynamic loads is a very significant question. This article introduces static aerodynamic force experiments and dynamic aerodynamic force experiments which were completed in hypersonic wind tunnels. They experimentally verify the existence of this type of load in normal directions. It is created by the asymmetrical nature of boundary layer transitions. In conjunction with this, they have clear and regular influences on the aerodynamic characteristics of long slender cones. Boundary Layer Transition, Reynolds Number, Aerodynamic Test; Induced Normal Force.
