The initial phase of the project has been completed successfully. The primary
objective of Phase 1 was to evaluate the touchdown dynamics (including slideout) of a subscale
vehicle/parachute combination with 2.0 lb/ft2 parafoil loading. This phase used a four-foot
model of the X-23 shape combined with a smaller parachute to obtain this loading. Using
technology from the DFRC Spacewedge project, the time span from start to first flight was less
than three months. The model was air-launched from a Cessna aircraft at the California City
airfield and immediately transitioned into parachute-borne flight. The vehicle/parachute
combination was then manually flown via radio control to a smooth landing. The model was
instrumented to obtain touchdown impact accelerations and rates. Fourteen flights have been
made and all test objectives were met.
Phase 1 Planned Objectives
Evaluate the touchdown dynamics (including slideout) of the
subscale vehicle/parachute combination with 2.0 lb/ft2 parafoil loading. This
objective includes the effects of cross winds and lower flap settings.
Demonstrate flare capability.
Investigate the arrangement and positioning of parachute harness
mechanisms.
Measure preliminary stability and control of the subscale
vehicle/parachute combination.
Obtain photos and video recordings of vehicle flights.
