Abstract

A single-stage, 6.44-ft-diam ribbon parachute with no reefing has been developed for deceleration and recovery of the 130-lb Large Ballistic Re-entry Vehicle-2 nose cone. The parachute design makes use of both nylon for horizontal ribbons and Kevlar-29 for suspension lines and skirt band to save weight and volume. The results of five sled-launched, free-flight tests and an operational recovery at velocities of 600-875 ft/s, with corresponding dynamic pressures of 340-766 psf, are reported. Good agreement between experimental values and theoretical modeling is shown. Recovery procedures begin by jettisoning part of the initial re-entry mass before parachute deployment. An operational re-entry vehicle flight resulted in recovery of the payload (in two pieces) and the undamaged parachute.
