The purpose of this Major Qualifying Project was to measure the glide ratio of round parachute canopies with various vent areas and materials. The project was conducted in cooperation with the Natick U.S. Army Soldier Center. Twelve test canopies were created from both porous and non porous nylon materials using a newly designed canopy template. Each canopy was constructed with a unique vent area ranging from 2% - 14% in order to determine which produced the highest glide ratio. An experimental apparatus was designed to hold the canopies open in a wind tunnel flow. The lift and drag on each canopy was measured using a six-axis transducer. It was found that glide ratio increases as vent area increases for both materials.
