Wind tunnel investigations were conducted to probe the wake of a C-141 aircraft in an airdrop configuration. A rake with twelve 5-hole yaw head probes measured velocities at various positions in the wake, and these measurements were used to compute the vorticity of the wake. In addition, motion pictures and force measurements were taken with three differently sized extraction parachute models attached to the model aircraft by three extraction lines of different lengths. Correlation of parachute behavior with the airflow data indicates that the vortex shed by the inboard flaps and the fuselage-wing junction causes an instability in the performance of the smallest parachute models while the performance of the larger parachute models is relatively unaffected.
