AERODYNAMIC CHARACTERISTICS OF VARIOUS TYPES OF FULL SCALE PARACHUTES AT MACH NUMBERS FROM 1.8 TO 3.0

As an extension of studies previously completed in the von Karman Gas Dynamics Facility, a test was conducted in the Propulsion Wind Tunnel, Supersonic (16S), to determine the effect of Mach number on the drag, stability, and inflation characteristics of four types of parachutes. The parachute chara...

Description
Summary:As an extension of studies previously completed in the von Karman Gas Dynamics Facility, a test was conducted in the Propulsion Wind Tunnel, Supersonic (16S), to determine the effect of Mach number on the drag, stability, and inflation characteristics of four types of parachutes. The parachute characteristics were investigated at Mach numbers from 1.8 to 3.0 at pressure altitudes from 75,000 to 104,000 ft. Hyperflo parachutes were tested with 14 different roof configurations, hemisflo and conical parachutes with two different shroud line lengths and a butted skirt. A supersonic-guide-surface parachute was tested at various parachute-centerbody separation distances.
