Design of the Stern Control Surfaces and Prediction of the Motions of the Dolly Varden Buoyant Rise Test Vehicle,

Abstract

The stern control surfaces of a 60-foot version of the DOLLY VARDEN Buoyant Rise Test Vehicle were designed from the standpoint of dynamic stability in vertical flight. Computer predictions were made of the vertical flight trajectories of the vehicle. It was found that a cruciform configuration of all-movable, rectangular stern appendages with tip to tip span of 10 feet and chord length of 5 feet will provide adequate stability in vertical buoyant rise flight and required maneuverability for recovery. It was also determined that a net buoyancy of 20000 pounds would provide the required operational speed. (Author)
