Performance in free fall of 27 model parachutes of various designs was determined by drop tests conducted in the Goodyear Aircraft Corporation Airship Dock at Akron, O. Tested were models of the following types with 16,000 sq. in. in total canopy area: Solid, Flat, Solid Extended, Skirt, Solid Spherical, Solid Conical, Airfoil, Exeter Type 12, Guide Surface, Ring Slot, and FIST Ribbon. All models were tested at vertical terminal velocities of approximately 10, 15, 25 and 40 feet per second both for vertical and horizontal types of release. Results of the drop tests are inserted in the appendices and include a copy of the original data sheets giving the space coordinates of the parachute throughout the descent along with a descriptive remark on the parachute performance. The appendices also include a plan-view, oscillation, and trajectory curve for each of the drop tests analyzed completely, followed by a representative sketch of the parachute sketch of the parachute canopy in question.
