Patent number: 6676071Abstract: Guidance of a gliding vehicle is disclosed. A method of the invention allows the range of the glide phase of a gliding vehicle to be maximized, while satisfying final flight path angle and aimpoint requirements. The method controls the time-of-flight of the gliding value to a desired value. The time-of-flight control can correct for winds, off-nominal launch conditions, and rocket motor variations, among other factors. Both time-of-flight control and range and cross-range maximization can be achieved by the inventive method, utilizing a compact closed-loop approach.Type: GrantFiled: June 21, 2002Date of Patent: January 13, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Craig A.

Patent number: 6676074Abstract: A drag damper for use on a rotary wing aircraft rotor comprises a body defining two variable volume chambers linked by a piston. The chambers are filled with fluid and are connected by a restriction port (35) and by a channel (32) of larger cross-section than the restriction port. A secondary piston slidable and pressure-tight piston is fitted in the channel and loaded by an elastic bias (34). The equivalent mass of this secondary piston (33) and of the fluid which it displaces, and the stiffness of the elastic bias (34) are such that the secondary piston is resonant in the channel (32) at the rotation frequency of the rotor, to filter the dynamic component at this frequency of stresses applied to the damper (20).Type: GrantFiled: February 3, 2003Date of Patent: January 13, 2004Assignee: EurocopterInventors: Elio Zoppitelli, Philippe Legendre

Patent number: 6663050Abstract: A kite in the shape of an aircraft having one or more wings. The number of wings can vary due to novel V-shaped connection members employed together with strut rod members cut to predetermined lengths. The connection members are preformed V-shaped connectors slidably mounted to spar members disposed in open-ended sleeves in the leading and trailing edges of a wing and may be oriented to receive strut members form either above or below the wing, for efficiency manufacturing, ease in assembly, and minimum exposure to breakage during operation, storage and transport. Additional connection members may be added to the spar members to receive strut members connected to additional wings thereby allowing for an airplane kite having one wing, two wings, three wings, or more. Multiple-V connectors may be combined to create hubs for propellers or wheels that rotate when they encounter a front wind. Ram air openings are utilized in the fuselage of the kite to maintain the shape of the fuselage and the angles of wings.Type: GrantFiled: January 8, 2003Date of Patent: December 16, 2003Inventor: Don Tabor

Patent number: 6644596Abstract: A system for deployment of a vacuum-packed inflatable structure includes a primary cylinder with a primary valve that can be opened under a primary applied force for discharging a primary pressurized fluid into the inflatable structure. A first connecting arrangement extends between the primary valve and an inflatable actuator bag. A secondary cylinder has a secondary valve movable under a secondary applied force for discharging a secondary pressurized fluid into the inflatable actuator bag. With this arrangement, application of the secondary force to the secondary valve causes the secondary cylinder to inflate the inflatable actuator bag. This in turn causes the first connecting arrangement to open the primary value with the primary applied force and inflate the inflatable structure.Type: GrantFiled: December 21, 2001Date of Patent: November 11, 2003Assignee: Air Cruisers CompanyInventors: Thomas A.

Patent number: 6634298Abstract: A fireset for a low energy exploding foil initiator (LEEFI) comprises a first capacitor for storing a level of electrical energy sufficient to fire the LEEFI, the first capacitor being in electrical communication with the LEEFI, second and third capacitors in electrical communication with the first capacitor for storing lesser levels of energy than is stored by the first capacitor, a diode in electrical communication with the capacitors for limiting charging of the second and third capacitors, and first and second resistors providing isolation among the capacitors. A trigger directs a pulse of electrical energy to a high speed switching transistor adapted to receive the pulse from the trigger and, in response there to, to dump the third capacitor. The third capacitor dumps through a silicone controlled rectifier to short the second capacitor to ground, to decrease the level of energy stored by the second capacitor.Type: GrantFiled: December 21, 1998Date of Patent: October 21, 2003Assignee: The United States of America as represented by the Secretary of the NavyInventor: Jim R. Denney

Patent number: 6591733Abstract: The present invention relates to a method and a device for handling artillery shells (14-16) when loading artillery guns (1) that have an integral shell magazine (9) fixed in the traverse system but independent from the elevating mass, which magazine on command feeds out shells (14-16) one by one with a specific linear velocity in the longitudinal axis of each shell. Each shell is subsequently transferred to the loading position for the gun by a loading pendulum (13) and cradle (6). The basic idea behind the present invention is that the outfeed velocity of the shells (14-16) from the magazine (9) shall be braked to zero in a brake module (12) mounted on the gun while they lie in a shell carrier (17, 18) mounted on the loading pendulum (13).Type: GrantFiled: October 16, 2001Date of Patent: July 15, 2003Assignee: Bofors Defence ABInventor: Sven-Erik Engström

Patent number: 6244187Abstract: A mushrooming bullet having a highly improved performance in the retention of the lead core within the bullet jacket subsequent to impact, and in performing effectively over a substantially wider velocity range, the bullet retaining its lead core within its jacket substantially 98-100% of its firings at high velocities, and mushrooming more effectively at lower velocities than conventionally manufactured bullets. The jacket is characterized by a base portion which has a substantially larger interior diameter than its shank portion, and a mouth portion which is substantially softer than its shank portion. The mushrooming of the nose portion of the core and the mouth portion of the jacket is effectively arrested by the harder thick shank portion when the bullet strikes a target, and thereby minimizes the loss of lead from the core.Type: GrantFiled: July 1, 1999Date of Patent: June 12, 2001Assignee: Federal Cartridge CompanyInventor: Lawrence P.
