This invention relates generally to aerodynamic decelerators and more particularly to the aerodynamic stabilization of parachutes having square canopies. When dropping a store such as a sonobuoy into the ocean from a high altitude it is necessary to assure proper orientation upon impact. This requires the use of a parachute which has high drag to slow the store's descent and stability to minimize its oscillations. Parachute instability, caused by destabilizing aerodynamic side forces on the canopy, is translated to the store through the parachute's suspension lines, causing the store to oscillate, adversely affecting impact orientation. An air-deployed payload which has a video camera mounted therein for transmission during air descent also requires a parachute with high drag efficiency and extreme stability to prevent oscillation of the payload during descent.
