Design of a Passively Reefed, Collapsible Drogue Parachute System

Testing Small CPAS Parachutes Using HIVAS

“…This same unit was used to test a candidate drogue system for the X-37 approach and landing test vehicle (ALTV). 3,4,5 HIVAS allows using the full scale hardware while a wind tunnel would require either a large cross section (and therefore expensive run time) or using subscale models with inherent differences in stiffness and resolution. However, because the deployment is not representative of flight, inflation parameters cannot be determined from HIVAS.…”
