Wind tunnel studies of a 1:56 scale non-powered model of the C-141A jet transport indicate the following characteristics of the flow field which affect the deployment of paratroops and cargo from the side doors and from the rear cargo ramp: downwash occurs across the side doors when the petal doors are closed, the flow beneath the side doors is inclined toward the centerline; and upwash occurs between and behind the petal doors when the doors are open 65 degrees. An analytic approximation of the effect of engine exhaust on the wake shows that the performance of a single parachute may not be significantly affected, but that of clustered extraction parachutes would be influenced by the engine slipstream.
