摘要: A wingsail assembly in which at least one thrust wing is mounted for free rotation about an upright axis and defining by its free rotation a trimming circle. The assembly includes a first control airfoil freely pivoted on a first boom extended upstream of a thrust wing, the first boom being of a length such that the first auxiliary control airfoil is within the trimming circle and a second control airfoil mounted downstream of the first control airfoil within the trimming circle and settable for controlling the angle of attack of the first control airfoil to the wind which in turn provides a turning moment for controlling the angle of attack of the thrust wing to provide thrust levels required for all normal sailing conditions. The assembly further moves the thrust wing to bring the instantaneous center of pressure of the thrust wing at different angles of attack into closer proximity to the upright axis and reduces the turning moment required of the first control airfoil, and in which the first control airfoil is freely pivoted about an axis ahead of all combined center of pressure locations for the first and second control airfoils.

摘要: A fin (1) for a windsurf board is constructed from fibers (5) which have a preferred fiber direction with the majority of the fibers lying in this direction, the preferred direction extending at an acute angle (a) to the longitudinal axis (4) of the profile of the fin blade (2). This allows the fin to distort and to change the properties of its profile in a defined manner when loaded.

摘要: An improved propulsion system is provided for inboard motor boats with planing-type hulls. A straight propeller shaft is passed through the bottom of the hull at an angle shallow enough to present a portion of the propeller above the bottom of the hull aft of the transom thereby providing a propeller that operates partially above the running water line during planing conditions. The benefits of a planing-type hull and a surface-drive propulsion system is economically and efficiently combined in a new design for inboard motor boats. The improved design is inexpensive to manufacture, install and maintain.

摘要: Essentially one-half of the circumference of the propeller of the marine vessel is arranged in a tunnel having a flow-favorable cross-sectional configuration which follows the flow lines of the water. At the starting region of the tunnel there is arranged a pivotable control plate which can be moved out of a retracted position where it lies in the surface of the tunnel into an extended position removed or remote from the aforesaid retracted position, in order to detach the flow of the water from the surface of the tunnel during rapid vessel travel. The propeller which is driven at a high rotational speed accordingly operates as a partially or semi-immersed propeller. The vessel floor and the control plate are interconnected by an elastically deformable cover plate which is secured to the vessel floor and the control plate in a bending or flexurally resistant fashion. This cover plate, both in the retracted as well as in the extended position of the control plate, affords a particularly flow-favorable covering of the gap or space formed between the vessel floor and the control plate. The front edge of the control plate is connected with the vessel hull by means of bearing or pillow blocks movable in the direction of travel of the vessel. The bearing blocks possess arm members which are increasingly elastically deformable in the direction of the retracted position of the control plate.

摘要: A tilt mechanism (10) for a marine propulsion device has a swivel bracket (13) pivotally attached to a transom bracket (11). A trim pin (21) is carried by a trim pin carrier (27) which is pivotally attached to the swivel bracket (13). The trim pin (21) travels in cam tracks (20) on the transom bracket (11) and engages notches (22, 23, 24) in the cam tracks (20) to establish trim and tilt positions for the propulsion device. An axial step (36) in the cam track (20) shifts the trim pin (21) to a return cam surface (25) to allow automatic return from the uppermost to the lowest position.

摘要: The invention pertains to a propeller pocket for reducing the draft of propeller driven marine craft, and the propeller pocket of the invention utilizes an increasing vertical dimension in the direction of the craft stern, the pocket being defined by planar surfaces, and the water within the pocket being "gathered" as the water approaches the stern to minimize cavitation at the propeller. The pocket is advantageous for use with either inboard, inboard/outboard or outboard driven installations and provides increased drive efficiencies with a reduction in hull draft.

摘要: An engine driven outboard drive unit for propelling a watercraft has a vertical drive shaft driving a horizontal propeller shaft on which a propeller is mounted. The drive unit has a gearcase torpedo which houses both the propeller shaft and an annular exhaust gas passage. The exhaust passage discharges aft through the plane of the propeller. A small annular projection is formed around the aft end of the torpedo to improve high speed performance.

摘要: A marine propulsive apparatus and a device and method for increasing the apparatus'' efficiency by controlling the amount of wetting of the apparatus over a range of speeds. A housing, mounted in a cavity formed in the stern of a ship, encloses a drive shaft connected to a propeller. A control surface is pivotally connected to the hull of the ship ahead of the propeller and in a raised position contacts the stern portion of the hull to form the upper wall of the cavity. A hydraulic device is used to raise and lower the control surface, the latter directing the flow of water across the propulsive apparatus. As the speed of the ship increases wetting of the propulsive apparatus is decreased.
