Abstract:
Dispositif pour la transmission bidirectionnelle de données entre un mobile énergétiquement autonome et une station de contrôle et de commande, sachant que ladite transmission bidirectionnelle de données s'effectue grâce à une fibre optique (FO) reliant ladite station de contrôle et de commande audit mobile énergétiquement autonome, et venant s'enrouler en spires jointives autour d'un tambour fixe (T) centré autour d'un axe (Δ), embarqué sur ledit mobile énergétiquement autonome; ledit tambour fixe (T) comprend : - un circuit de conversion bidirectionnelle optique/électrique (CC2) associé à l'extrémité libre de ladite fibre optique (FO), et - un mécanisme de dévidement tournant (DEV2), monté coaxial avec l'axe (Δ) dudit tambour (T), dont la vitesse de rotation est fonction de la vitesse de déplacement dudit mobile énergétiquement autonome.

본 발명은 기동성능이 향상된 수중 이동장치를 제공하기 위한 것이다. 본 발명에 의한 기동성능이 향상된 수중 이동장치는, 추진기가 설치된 이동장치 바디와, 이동장치 바디의 외면에 이동장치 바디의 길이 방향으로 마련되는 복수의 장홈과, 이동장치 바디의 외면으로부터 돌출될 수 있도록 이동장치 바디의 복수의 장홈에 이동장치 바디의 길이 방향으로 배치되어 내외 방향으로 이동 가능하게 설치되는 복수의 릿지와, 복수의 릿지를 이동장치 바디의 외면으로부터 돌출되도록 이동시키기 위해 이동장치 바디 내부에 설치되는 릿지 구동기와, 이동장치 바디의 수중 이동 중 이동장치 바디의 받음각이 일정 각도 이상 커질 때 릿지가 이동장치 바디의 외면으로부터 돌출되어 이동장치 바디의 외면에서 와류를 형성함으로써 이동장치 바디에서의 유동 박리를 방지할 수 있도록 릿지 구동기를 제어하는 컨트롤러를 포함하는 점에 특징이 있다.
Abstract:
A control actuator system. The novel system includes a control surface mounted on a body and adapted to move in a first direction relative to the body, and a first mechanism for storing energy as the control surface moves in the first direction and releasing the stored energy to move the control surface in a second direction opposite the first direction. In an illustrative embodiment, the system is adapted to rotate an aerodynamic control surface of a rolling missile, and the first mechanism is a torsional spring arranged such that rotating the control surface in the first direction winds up the spring and releasing the spring causes the control surface to oscillate back and forth, alternating between the first and second directions. In a preferred embodiment, the spring has a spring constant such that the control surface oscillates at a natural frequency matching a roll rate of the missile.
Abstract:
An underwater vehicle comprising, a housing, an internal guidewire dispenser (20) for storing and deploying a guidewire (30) , and a splice cavity (40) defining a storage space (42) , for carrying and deploying a splice between the internal guidewire and an external guidewire and excess guidewire resulting from splicing the internal and external guidewires .
Abstract:
Method and means for a regulator for the servo control of a marine craft, for instance a torpedo, with variable speed and angle of attack. A first sensor (1) monitors the angle of attack, whilst a second sensor (8) monitors the depth of the craft. A revolution counter (3) and a filter (4) create an acceleration-compensating signal which is substracted from an angle-of-attack signal emitted by the first sensor (1), whereupon the signal is transmitted to a rudder servo system.
Abstract:
Die Erfindung betrifft ein Verfahren zum Steuern eines Torpedos (1) zu wenigstens einem Ziel. Zur Erhöhung der Reichweite des Torpedos (1) taucht der Torpedo (1) während seiner Fahrt zum Ziel (Z) ein- oder mehrmals in den der Wasseroberfläche benachbarten, oberflächennahen Bereich eines Gewässers (4) auf, wobei der Torpedo (1) jedoch auch in diesem oberflächennahen Bereich untergetaucht bleibt. Der Torpedo (1) fährt dann eine Funkantenne (10) in einen Überwasserbereich oberhalb der Wasseroberfläche aus und empfängt sodann Zielpositionsdaten des Ziels aufweisenden Positionsdaten über diese Funkantenne (10) und verwendet diese Positionsdaten, um das Ziel (Z) anzusteuern. Die Erfindung betrifft ferner einen Torpedo (1) mit einer Antennensektion (31) mit einer ausfahrbaren Funkantenne (10). Ferner betrifft die Erfindung eine derartige Antennensektion (31).
Abstract:
Embodiments of a buoyancy dissipater and method for deterring a vessel are generally described herein. In some embodiments, a volume of gas is generated from a propellant and diffused below a waterline of a vessel. The resulting gas bubble dissipates the buoyancy of the vessel providing a non-lethal deterring effect.
