A cover 10 and method for protecting a missile 15 with stowed wings 20 and connected to a vessel carrying it. The cover 10 includes a spoiler shaped front part 25 for covering a gap between the wings 20 of the missile 15 and the fuselage of the missile 15 for minimizing aerodynamic forces.

A device for improving the aerodynamic feature of a projectile is disclosed. The projectile has a front part and a rear part. The external diameter of the front part of the projectile is larger than the external diameter of the front end of a rear part of the projectile. The front end of the rear part of the projectile is conical having larger diameter at locations behind the front end. The device comprises an annular cut-off cone sleeve slidably disposable over the front part of the projectile. The diameter of the narrower end of the annular cone sleeve is slightly larger than the diameter of the front part of the projectile and the length of the annular cut-off cone sleeve is larger than the distance between the front end of the rear part of the projectile and a location on rear part having a diameter equal to the diameter of the rear end of the annular cut-off cone sleeve.

Methods and devices for adjusting a position of a flight control member relative to a base of an aircraft. The devices and methods include a joint that movably connects the flight control surface to the base. An extension member is connected to the flight control surface and extends through the joint. Adjustable linear members of the base are connected to the extension member and configured to adjust the position of the extension member. This adjustment results in re-orienting the flight control member relative to the base to adjust the flight of the aircraft.

Embodiments of a predictably fragmenting projectile having internally-arranged geometric features are disclosed herein. According to various embodiments, a predictably fragmenting projectile having internally-arranged geometric features can include a substantially solid core of a material; a substantially continuous and smooth outer ogive; a plurality of petals attached to the core and formed from the material, each of the plurality of petals can include a smooth outer surface and can be formed by two break lines formed on the inside of the petals; and a cavity that is located proximate to the core and inner surfaces of the plurality of petals. The fragmenting projectile can be configured to deform by at least one of the plurality of petals pivoting outwardly relative to the cavity.

A deliverable weapon, such as a missile, an artillery round, an aerial bomb, or a mortar round, having an explosive warhead, utilizes concentric annular sleeves that upon detonation provide placement of smaller fragments of an inner annular sleeve interstitially with respect to larger fragments of an outer annular sleeve in an expanding fragmentation curtain that contains expanding gases to increase the pressure of the explosion and the kinetic energy transferred to the fragments. In embodiments, the sleeves are comprised of ordered layers of spherical metal fragments encased in binder material and an outer casing.

A projectile device for establishing a wireless network and transmitting data within the network. The projectile device includes a motion sensor configured to measure at least one of an acceleration, angular velocity, or an orientation of the projectile device; an antenna configured for communication within a wireless network between the projectile device and at least one external device. The projectile device includes a processor configured to establish communication in the wireless network for receiving and/or transmitting a message between the projectile device and the at least one external device via the antenna and a wireless protocol that is determined by at least one of the acceleration, angular velocity, or orientation of the projectile device. The projectile device includes a damping agent arranged to impact movement of components of the projectile device, wherein a form factor of the projectile device is complimentary with a launching mechanism of the projectile device.

A projectile incorporates one or more spoiler-tabbed spinning disks to effect flow around the projectile and thus impart steering forces and/or moments. The spoiler tabs may be deployed only during steering phases of travel thus minimizing the drag penalty associated with steering systems. The disks are driven by motors and informed and controlled by sensors and electronic control systems. The spoiler tabs protrude through the surface of the projectile only for certain angles of spin of the spinning disk. For spin-stabilized projectiles, the disks spin at substantially the same rate as the projectile, but the disks may function in fin-stabilized projectiles as well. Any number of such spinning flow effector disks may be incorporated in a projectile, with the manner of functional coordination differing slightly for even and odd numbers of disks.

The method and apparatus for a remote weapon station or incorporated into manually-aimed weapons. The methodology requires use of a muzzle velocity sensor that refines the aiming of the second and subsequent fires or volleys fired from weapon systems. When firing the first volley a weapon uses an estimated velocity and, at firing, the muzzle velocity of a projectile is measured. When firing the second volley a weapon's fire control calculates an aiming point using the measured velocity of the first volley.
