Arnold Engineering Development Complex (AEDC) engineers at the National Full Scale Aerodynamics Complex (NFAC) assisted in recent testing of sub-scale parachutes for the next mission of the Orion spacecraft, Exploration Mission-1.
The testing, conducted in January in the 80-by 120-foot wind tunnel by a team of NASA, Jacobs Engineering, Airborne Systems and NFAC personnel, was to help improve the safety and reliability of Orion's landing.
The team tested 13 parachute configurations using a tether system to hold the parachute while measuring aerodynamic forces. The parachute was also allowed to fly freely in the tunnel, during which photogrammetry, measurement taken by photography, was used to gather data on aerodynamic characteristics of the parachute.
