摘要:
A marine vessel (100, 200, 500) comprising a hull (110), a propulsion system (120), a control unit (130) and a motion sensor system (140), where the propulsion system (120) comprises a first drive unit (120a) and a second drive unit (120b) separated by a longitudinal midship line (115) of the hull (110), where each drive unit (120a, 120b) is arranged to generate thrust (T) in a controllable thrust elevation angle (ωy,T) and in a controllable thrust azimuth angle (ωz,T), where at least the thrust elevation angles (ωy,T) are individually controllable, where the control unit (130) is arranged to estimate a pitch motion (ωy) and a roll motion (ωx) of the hull (110) based on input from the motion sensor system (140), and where the control unit (130) is arranged to suppress pitch motion and roll motion by the hull (110) by controlling the thrust elevation angles (ωy,T) and the thrust azimuth angles (ωz,T) of the first and second drive units (120a, 120b).

Bei einem motorischen Propellerantrieb (30) für ein Wasserfahrzeug (10) ist dessen Propellerwelle (64) um eine Achse (52), die im Ruhezustand des Fahrzeuges (10) etwa in einem Winkel zwischen Null Grad und etwa 15 Grad senkrecht zur Wasserlinie (14) des Fahrzeuges (10) ausgerichtet ist, verdrehbar gelagert und mit ihrem zumindest einen Propeller (46, 48) in den Innenraum (70) des Wasserfahrzeuges (10) hineinbewegbar und aus demselben herausbewegbar.
摘要:
The invented device foresees to actuate the moving of the ogive (1), bearing the propeller and determing the right or left turn, a mechanical drive group made by a conical couple with inside gear which constantly acts as power angled drive on the same ogive axis. Said ogive (1) is mounted on a tube (6) connected integral with the stern, housing a hydraulic drive (7) which rotates the ogive (1). The boat steering wheel acts on the hydraulic drive (7) which drives the ogive (1) determining the right or left turn.
摘要:
A number of embodiments of watercraft having jet propulsion units contained within a tunnel in the hull and wherein the jet propulsion unit is pivotal about a first transversely extending horizontal pivot axis for bringing the jet propulsion unit through trim adjusted positions to an upward out of the water position. In addition, the jet propulsion unit is rotatable about a horizontal longitudinally extending axis so that its downwardly facing water inlet portion may be rotated upwardly for access through an access opening in the hull for servicing. In one embodiment, the jet propulsion unit is only rotatable about the horizontal longitudinally extending axis. A number of embodiments of rudder assemblies are also depicted supported by the steering nozzle for generating steering effects when the steering nozzle is not generating a significant steering effect and which may be pivoted to an out of the water position for protection when underwater obstacles are struck.
摘要:
The invention relates to a ship drive (1) comprising a drive machine (2), a transmission (3), a propeller shaft (5) which is driven by the transmission (3), and a bearing arrangement with which the ship drive (1) can be secured to a hull (6) of the ship. The drive machine (2) and the transmission (3) are connected to each other by means of a connecting flange (4) and are arranged within the hull (6) of the ship. The invention is characterized in that a first bearing point which is designed as a rotary bearing (7) is arranged in relation to the rotational axis (15) of the propeller shaft (5) such that a bending moment (9) at the connecting flange (4) is optimized, said bending moment being caused by the propeller thrust (8) and the weight of the drive machine (2) and the transmission (3).
