An investigation has been conducted in the Langley 20-foot free-spinning tunnel to determine whether the effectiveness of a spin-recovery parachute would be influenced by a reduction, through the use of a shock absorber, of the opening shock load. In addition, the effects on the parachute opening shock load of varying the fabric porosity of the parachute canopy and the towline length were investigated.
