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.

Abstract: An optical storage system comprises a disk assembly, an optical assembly and a carriage assembly arranged to provide a high-performance, multiple-disk storage device. The disk assembly includes a plurality of disks axially spaced on a rotatably mounted spindle and configured to record data on pairs of opposing facing recording surfaces. The optical assembly includes a static optics package for generating a collimated optical beam used to store and retrieve data from the disks, and a beam distribution system for directing the optical beam to a selected recording disk surface. The carriage assembly includes a plurality of carriage arms supporting head assemblies that are arranged for insertion between the pairs of opposing recording disk surfaces. The head assemblies are further arranged in facing relation to the recording disk surfaces to receive the optical beam from the beam distribution system and direct the beam onto the disk surface.
