摘要： An aeromechanically stable sabot system that includes a center of gravity that is placed forward of an aerodynamic center of the aeromechanically stable sabot system when in steady-state flight. By placing the center of gravity forwards of the aerodynamic center, the sabot system exhibits positive longitudinal and directional stability. To illustrate, the sabot system and/or portions thereof will return to stable flight after being disturbed in pitch (vertically or about a transverse horizontal axis) or yaw (side to side or about a vertical axis) when traveling horizontally.

摘要： A method, a device, and a system using the device, for avalanche control using an unmanned aerial vehicle to transport an explosive charge to a snow surface or snowpack. A holder of the device holds the explosive charge in a container. A receiver of the device receives a release signal. The holder releases the explosive charge in response to the release signal. A coupler couples the holder to the unmanned aerial vehicle. The explosive charge is fuzed to detonate after release from the holder to trigger an avalanche.

摘要： A winged external guidance frame placed on the muzzle that can couple with a projectile while exiting the barrel utilizing the kinetic energy of the projectile to travel to the target while the accuracy is provided by on board electronics and corrected using the wings. Alternately a reusable unmanned aerial system that travels in the speed and direction of the projectile and couples with the projectile as it exits the barrel.

摘要： An aircraft comprises a weapons bay, the weapons bay comprising a cavity having an opening through which stores may be deployed, and a door assembly for exposing/closing the opening of the cavity. A first store is held in the cavity via a launcher and a first structure is disposed inside the cavity, for controlling the aero-acoustic environment. The first structure for controlling the aero-acoustic environment is removeably mounted in the weapons bay, such that if the first store is exchanged for a second, different, store, the structure for controlling the aero-acoustic environment may be unmounted from the weapons bay and removed, to be exchanged for a second, different, structure for controlling the aero-acoustic environment.

摘要： The present disclosure provides a payload activation device. The payload activation device comprises a camera having a fixed focal length, arranged to capture an image of an object on a platform for carrying a payload having the payload activation device, wherein, when the payload is in a first position relative to the platform, the image of the object is in a first focused state and, when the payload is in a second position relative to the platform, the image of the object is in a second focused state. The payload activation device also comprises a processor configured to determine whether the image of the object is in the first focused state or the second focused state and to cause actuation of an activation mechanism within the payload when the image of object is in the second focused state to activate the payload. The present disclosure also provides a deployable payload having the payload activation device and an aircraft for carrying the deployable payload.

摘要： A munitions rack includes a munitions rack structure that houses multiple compact ejectors. The structure includes a pair of internal longitudinal ribs, inboard of a pair of external longitudinal ribs. A spine of the munitions rack structure links all the ribs, and the munitions rack structure may be formed out of a single piece of material. The ribs define a pair of side recesses on the port and starboard sides of the bomb, which each may be further subdivided into a forward pocket and an aft pocket. Removable ejectors are located in the pockets. The ejectors may receive pressurized gas from pressurized gas source(s) located outside of the ejectors. The ejectors may each have multiple forward pistons and multiple aft pistons. The ejectors may include pitch control valving to control the relative amounts of pressurized gas sent to the forward piston(s) and aft piston(s).

摘要： An airburst delivery system that may provide for effective delivery of firefighting material to forest fires. The system generally utilizes an explosive charge to detonate a frangible containment vessel filled with firefighting material above the earth and typically above fire in a forest canopy. The resulting expanding sphere of water and related shockwaves provides a multi-effect interaction with the fire resulting in multiple water soakings combined with the sue of the vacuum and compression created by the shockwave to starve the fire of fuel and oxygen.

摘要： An unmanned aerial combat vehicle system is disclosed. The system provides for an unmanned aerial combat vehicle that is capable of performing reconnaissance, disrupting enemy communications, or delivering a weaponized payload. The unmanned aerial combat vehicle may also be equipped with a cloaking mechanism, where it can mask it's heat signature, or simulate an image on its outer surface.
