Investigation on Separation Interference of Typical Multi-Body Vehicle in Supersonic Conditions

A set of quasi CAV model composed of a carrier model and a internal store model was designed consulting opening documents, and it was used to study the multi-body interference during separating by grid force measurement at supersonic in 0.6m×0.6m transonic wind tunnel. The results show that the aerodynamic characteristics of the loading model would change dramatically during the separation. Two factors induced this dramatic change of its aerodynamic characteristics. The first comes from the unbalance development of wake flow and the head shock wave during the loading model moving from the wake flow region to free stream flow region. And the second comes from the huge change of interference region induced by the asymmetric base.
