Keywords: dynamic derivatives, close proximity

An exploratory experimental test programme investigating the dynamic derivative interference effects of a parent airframe on a store revealed changes in the pitch dynamic derivatives dependent on the relative position of the store with respect to the parent airframe, and the parent angle of attack. The tests were performed on 1/12th scale models at free-stream velocities varying from 30 m/s to 43 m/s and the Low Speed Wind Tunnel of the CSIR.
