INVESTIGATION OF AN ATTACHED INFLATABLE DECELERATOR SYSTEM FOR DRAG AUGMENTATION OF THE VOYAGER ENTRY CAPSULE AT SUPERSONIC SPEEDS

Abstract

A test was conducted in the 16-ft supersonic wind tunnel to obtain deployment, inflation, and steady-state characteristics of an inflatable decelerator attached to the base of a Voyager entry capsule. Deployments were made at Mach numbers of 2.2 and 3.0 at a free-stream dynamic pressure of 120 psfa. The data obtained show that the preinflation method utilizing vaporization of sufficient liquid solution to completely inflate the decelerator volume resulted in full-inflation times of less than 0.25 sec. The decelerator remained fully inflated after each deployment and exhibited excellent stability.
