摘要:
An air vehicle (10), such as a munition like a guided bomb or missile, has a control system (12) that allows control surfaces (14, 20, 22) to be mechanically uncoupled from one or more actuators (46, 48) to allow the control surfaces to freely move (rotate) relative to a fuselage (16) of the vehicle (10), for example allowing the control surfaces to "weather vane" by assuming an orientation corresponding to the direction of airflow past the air vehicle (direction of airflow relative to the air vehicle). When active positioning of the control surfaces is desired, the control surfaces may be mechanically coupled to one or more actuators that are used to position the control surfaces. The selective coupling of the actuator(s) and the control surfaces may be accomplished by selectively coupling together a sleeve (36, 38) that is mechanically coupled to the control surfaces, and a nut (62) that moves along a shaft (32, 34) of an actuator, for example using a resilient device (64, 114, 118).
摘要:
A bomb for deployment from an air vehicle includes a rocket motor (1) for propelling the bomb. The rocket motor includes propellant (5) which at least partially defines a void (11) downstream of an initial burning surface. As the propellant (5) is burned the void 11 will be exposed, increasing the surface area of the burning surface (9) of the propellant (5) to increase the thrust of the rocket motor.

A method of defeating an incoming missile (120), such as a rocket propelled grenade, includes soft launching an interceptor missile (10), and then using pitch over motors of the interceptor missile to alter course of the missile to a desired interception direction. By launching at a relatively slow speed, such as a speed less than or equal to 40 m/sec (130 ft/sec), the interceptor missile may reach the desired interception direction within 250 milliseconds of launch. The interceptor missile may be able to cover substantially all interception directions over a hemisphere or greater extent around a launch location. For example, the interceptor missile may be launched vertically from a ground vehicle, and be capable of altering course to any above-ground trajectory within 250 milliseconds.
摘要:
A weapon system and corresponding ammunition for causing less-than- lethal effects to a target employ a projectile fired from a rifle-mounted, rifle- operated or dedicated rifle-like device and configured for generating less-than- Iethal effects to a human target. The projectile includes a rocket motor configured to mitigate velocity decay of the projectile. The rocket motor is preferably a sustainer motor for maintaining a roughly constant cruise velocity of the projectile.

Bei einer multifunktionalen Service- und Testeinrichtung für unbemannte Flugkörper, mit einem mit dem Flugkörper (1) verbindbaren Service-Gerät (2) und einem mit dem Service-Gerät (2) verbindbaren externen Computer (4), wobei das Service-Gerät (2) Test- und Service-Hardware enthält; wobei Test- und Service-Software in einem Speicher des externen Computers (2) gespeichert ist und auf dem externen Computer (2) läuft, weist das Service-Gerät (2) zumindest die folgenden Hardware-Komponenten auf: zumindest eine Durchfluss-Messeinrichtung (28A) für zumindest ein zum Flugkörper (1) zuzuführendes Test-/Service-Fluid; zumindest ein schaltbares Ventil (28B) für das Test-/Service-Fluid; Schalt- und Regelungseinrichtungen (29) für dem Flugkörper (1) zuzuführende elektrische Energie; zumindest einen Trenntransformator (29A; 29B) zur Entkopplung extern zugeführter elektrischer Energie vom Stromnetz des Service-Geräts (2); und weist das Service-Gerät (2) einen Kommunikations- und Steuerungsrechner (27) zur Kommunikation mit dem Flugkörper (1) und mit dem externen Computer (4) sowie zur Steuerung der Hardware-Komponenten auf.
摘要:
A projectile (10) arranged to be launched from a launcher (12), the projectile comprising a source of compressed gas (1) and control means (23) for controlling the release of the compressed gas, in which the control means (24) is arranged so as to release the compressed gas in response to the launching of the projectile (10) from the launcher (12). Typically, the control means (24) is a valve, arranged such that the application of gas pressure from the launcher (12) is required in order to release the compressed gas, but the application of gas pressure must abate before the compressed gas is released. Thus, the compressed gas may only be released once the projectile (10) has cleared the launcher (12).
摘要:
Methods and apparatus for delivering a missile may operate in conjunction with a missile comprising an outer skin. The missile may be configured in a closed position and an open position. In the open position, an aperture is opened in the outer skin, for example to supply air to an air-breathing engine. In the closed position, the aperture is closed.
摘要:
An interception system for intercepting incoming missiles and/or rockets including a launch facility, a missile configured to be launched by the launch facility, the missile having a fragmentation warhead, a ground-based missile guidance system for guiding the missile during at least one early stage of missile flight and a missile-based guidance system for guiding the missile during at least one later stage of missile flight, the missile-based guidance system being operative to direct the missile in a last stage of missile flight in a head-on direction vis-a-vis an incoming missile or rocket.
