摘要： A deployable, linear explosive structure includes a split tube, an explosive coupled to the split tube, and a fragmentable or non-fragmentable projectile disposed with respect to the explosive. The split tube can be rolled into a non-deployed state in which the split tube has a flat, rolled profile. The split tube also can be deployed from the non-deployed state to a deployed state in which the split tube is extended along its length and has a curved cross-section along its length. The split tube provides support of the explosive structure in the deployed state. The split tube also provides smaller storage and transportation volume for the explosive structure when rolled in the non-deployed state.

摘要： A launch system and method for an aircraft include a first ejector, and a second ejector. The first ejector and the second ejector are configured to cooperate to releasably retain a first store having a first length. Each of the first ejector and the second ejector is configured to releasably retain one or more second stores having a second length that differs from the first length.

摘要： A launching device and associated methods can be utilized to launch an underwater running body from a platform such as a watercraft. The launching device may include a ramp, which extends along a longitudinal ramp axis, and a propellant deflection unit. The ramp may enclose an underwater running body with a propulsion unit underwater. The launching device may activate the propulsion unit, which then emits a propellant. The propellant deflection unit deflects the emitted propellant into an outlet direction. This outlet direction of the propellant may be directed perpendicularly or obliquely away from the platform.

摘要： A launcher for launching a flying vehicle, such as a projectile or missile, includes a cutter for cutting a line, such as an umbilical line, that is coupled to the vehicle prior to launch. An example of a line is a tube for providing cooling for onboard components of the vehicle, such as a seeker of the vehicle. The cutter may be part of a mount of the launcher for mounting the line and other components, such as a compressor. The cutter may be configured so that as the vehicle translates relative to the launcher during the initiation of launch, the line moves against the cutter, severing the line. The cutter may retract after severing the line, for example being pulled away from the vehicle (and into the mount) by a spring mechanism.

摘要： A projectile including: a shell; a rotating shaft; and a screw which can be rotated by the rotating shaft. The screw and the shell include, respectively, a stop and a counter-stop opposite each other. The screw is capable of sliding axially between a first position, in which a non-zero clearance is provided between the stop and counter-stop, and a second position, in which the stop and counter-stop are in contact. An elastic return element reversibly deformable between a first and a second state of stress which correspond to the first and second positions of the screw, respectively, the stress of the first state being lower than the stress of the second state.

摘要： An erection device and method for the marine hot launch of a rocket are provided. The erection device includes a launch vessel, a launch pad, an erection assembly, a guide member, a driving cylinder, a sliding member, and a connecting member. The sliding member cooperates with the guide member and is driven by the driving cylinder to move linearly. The connecting member has one end hinged to the erection assembly at a certain angle and the other end connected to the sliding member and is configured to move with the sliding member to drive the erection assembly to be erected on the launch pad. The erection device and method can achieve an effective erection of the rocket for marine hot launch with a desired erection effect and high stability.

摘要： Firearm bolt assemblies and firearms including the same are described. In embodiments the firearm bolt assemblies are configured to localize compressive forces applied during a transition from an initial position to a firing position to a first cam system on one side of the firearm bolt assembly, and to localize compressive forces applied during a transition from the firing position to the initial position to a second cam system another side of the firearm bolt assembly. Localizing the forces in that manner enables the use of a first cam system that is relatively robust compared to the second cam system.
