Book excerpt: The deployment characteristics of a 1/8-size dynamically and elastically scaled model of an inflatable parawing suitable for the recovery of an Apollo-type spacecraft were investigated in free flight and in the Langley transonic dynamics tunnel using a model which was mounted to permit limited angular freedom. The deployments were of a passive type; that is, there was no powered reel-in or reel-out of the suspension lines. However, a braking system was used to attenuate the dynamic loads in the suspension lines. The deployment technique was developed in an initial series of wind-tunnel tests. By utilizing the equipment and technique evolved from the wind-tunnel studies, successful free-flight deployments were accomplished and the transient loads associated with the deployments were measured. These results were compared with the results of subsequent wind-tunnel tests.
