AN INVESTIGATION OF VARIOUS TYPES OF DECELERATORS AT MACH NUMBER 2.8

Abstract

A test was conducted in the 16-ft supersonic wind tunnel to obtain deployment and steady-state drag, inflation, and stability characteristics of a metal ballute, a cloth ballute, a cloth ballute with a burble fence, a parasonic parachute, and a hyperflo parachute. All decelerators were tested at a Mach number of 2.8 at a dynamic pressure of 120 psfa. The data obtained show that a method of pre-inflation utilizing a methyl alcohol/water solution reduced the time required for the drag load to reach the steady-state value. This reduction of time permitted the metal ballute to attain full inflation.
