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.

A non-lethal projectile comprises a rear portion in the form of a cylinder (2) coupled to at least two symmetrical petal-like impact elements (1) which are capable of opening upon leaving a bore and are designed to form, in a closed configuration, a cylinder having an outside diameter equal to the diameter of the cylindrical rear portion and also having an axial cylindrical opening which transitions into an axial opening in the cylindrical rear portion of the projectile. The petal-like elements have an asymmetrical cross section and an inner conical groove, the base of which is disposed at the rear portion-end of the projectile, wherein, in the front portion, each petal-like element has a unidirectional relief.

Curved airflow plate fins deployed upon rockets to guide the trajectory under the action of given forces. The fins are comprise relatively high gauge metal. They are located on the rocket in a triangular arrangement. When deployed. the fins contribute to deceleration and breaking. The airflow plates can be extended outwardly from their housing, and then rotated transversely with respect to the longitudinal axis of the rocket. The airflow plate fins have geometric openings to improve their performance against incoming forces given that under supersonic speed. Their curved shape increases the capabilities of friction between the forces acting against them.

In accordance with at least one aspect of this disclosure, an actuation system for a guided munition, includes a reservoir disposed in a guided munition body housing a compressible fluid in a compressed state, a fluid path connecting the reservoir in fluid communication with a heat exchange volume, a throttling orifice disposed in the fluid path configured to expand the compressible fluid, and an actuation path connecting the heat exchange volume in fluid communication with a moveable component. The actuation path can be configured to supply pneumatic pressure to the moveable components.

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.

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.
