Extract

Hypersonic projectiles are sometimes launched using a castellated sabot which links with matching cavities in the missile. After launch and the removal of the sabot the boundary layer over the vehicle flows past these cavities which act as a kind of roughness. Experiments were made to discover the effect of this ‘roughness’ on the flow over a flap or flare placed downstream of the cavities. Tests were made with both laminar and turbulent boundary layers, the turbulent flow being induced by vortex generators placed near the nose of the models.
