Shotgun shell
A shotgun cartridge having a weighted wad for controlling the separation point between the wad and the shot load. The wad having a tail portion and a nose portion with the nose portion shifting the center of gravity of the wad axially forward away from the center of pressure compared to where the center of gravity would be if the nose portion was not weighted thereby controlling the shot load separation and enhancing the shot pattern.
Container for aerial delivery of goods
A container for dropping from an aerial vehicle comprises a bottom section and a plurality of side walls. Wings are connected to the upper edges of the side walls to allow pivoting of the wing between a passive position, in which the wing extends along the corresponding side wall, and a deployed position, in which the wing extends substantially transversely relative to the corresponding side wall. Reinforcing units increase the bending stiffness of the wings. Retaining units limit pivoting of the wings beyond the deployed position.
Apparatus for a vehicle
Apparatuses for a projectile are provided, the projectile configured for weapons band launching, examples of the apparatus comprising a body, an inflation system and external walls. The body is inflatable by the inflation system, from a deflated configuration having a first volume to an inflated configuration having a second volume, greater than the first volume. The external walls are deployable from an undeployed configuration to a deployed configuration responsive to the body being inflated. In the undeployed configuration and at an operating airspeed, the center of pressure is located at a first position with respect to the projectile. In the deployed configuration the external walls provide a deployed external surface geometry exposed to an airflow corresponding to the operating airspeed, such that the center of pressure is located at a second position with respect to the projectile, different from the first position.

Passive and active stability systems for ballistically launched multirotors
A ballistically launched foldable multirotor vehicle has a central body frame. A battery is located in an upper vertical location of the vehicle and positions a center of mass of the vehicle to provide aerodynamic stability during a launch. Fins are attached to the central body frame such that aerodynamic forces on the fins shift an aerodynamic center (AC) of the vehicle downward below the center of mass of the vehicle. Three or more foldable arms are attached to the central body frame via a hinge and exist in two states—a closed state where the foldable arms are parallel to a central body axis, and an open state (after launch) where the foldable arms extend radially outward perpendicular to the central body axis. Rotors mounted to each foldable arm are controlled by a motor to enable flight.
Fuse with reversible airbrake
A fuse is provided with a reversible airbrake intended for a projectile, wherein the airbrake is arranged such that errors which occur in the flight path of the projectile can be corrected by performing one or more extensions and retractions of the airbrake. The airbrake includes at least two braking surfaces symmetrically arranged each behind a respective protective device arranged on the casing surface of the fuse, wherein the brake surfaces can be extended and retracted in a rotational direction behind the at least two protective devices via a twist shaft arranged centrally in the fuse.

Guided projectile and countermeasure systems and methods for use therewith
A guided projectile including a projectile housing, a first sensor, and an air brake detachably coupled to the projectile housing. The air brake is deployable from a flight configuration to a braking configuration. A processor is configured to monitor, based on data received from the first sensor, a proximity of the at least one intercepting object relative to the guided projectile, wherein the guided projectile is configured to advance towards a target location on a first target trajectory. The processor is also configured to deploy the air brake to cause the guided projectile to veer from the first target trajectory to evade the at least one intercepting object, and detach the air brake from the guided projectile to enable the guided projectile to advance on a second target trajectory that is offset from the first target trajectory, wherein the first target trajectory and the second target trajectory have the same target location.

Inflatable bladder fairing recovery system with repositioning mechanisms and method
Embodiments of the present invention relate to a launch vehicle fairing recovery system and method using inflatable bags and fairing repositioning mechanisms. Embodiments of the present invention also relate to providing a system or mechanism to flip the fairing into the proper floating position. In some embodiments, the fairing has an inner surface and an outer surface, where the outer surface is exposed to the atmosphere when the fairing is interconnected to a spacecraft, and one or more inflatable bags interconnected to the outer surface of the fairing, where when the fairing is interconnected to the spacecraft the one or more inflatable bags is empty, and after the fairing separates from the spacecraft the one or more airbags are filled with pressurized gas and/or hydraulic liquids.
