ABSTRACT:
The disclosed system and method for improving aerodynamic stability of aeronautic vehicles generally includes an ejectable grid fin adapted for releasable engagement with aeronautic vehicles. The grid fin is generally configured to optimize the flight performance characteristics of the aeronautic vehicle taken in engaged combination with the grid fin as compared with the flight performance of the aeronautic vehicle taken alone. Disclosed features and specifications may be controlled, adapted or otherwise optionally modified to improve the aerodynamic stability and/or control of a variety of deployed aeronautic vehicles. Exemplary embodiments of the present invention generally provide ejectable grid fins that may be used in conjunction with missiles mounted on an eject rail of an aircraft.
