Comparison of Parachute Performance at Transonic Mach Numbers for Conical Ribbon Parachutes Constructed of Nylon and Kevlar-29 Materials

Abstract

Tests were conducted in the Propulsion Wind Tunnel to determine deployment and inflation characteristics which would allow comparative performance evaluations to be made of four conical ribbon parachute versions constructed of either nylon and/or Kevlar-29 materials. In general, parachutes constructed of Kevlar-29 material withstood the same opening shock loads while exhibiting a shorter damping time for inflation drag loads compared with nylon- constructed chutes. The least postinflation drag dynamics were exhibited by those parachutes which contained Kevlar-29 materials. A significant savings in weight and volume was realized by using Kevlar-29 as a substitute for nylon in parachute construction.
