20090203270 | REVERSE MECHANISM FOR A JET SYSTEM - A jet propulsion system includes an inlet receiving a fluid, and a housing defining a discharge nozzle through which fluid is discharged to provide propulsion of a vehicle in a first direction. The jet propulsion system also includes a reverse mechanism movable between a deployed position redirecting fluid from the discharge nozzle toward the first direction and providing propulsion of the vehicle in a second direction substantially opposite the first direction and a non-deployed position allowing fluid to exit the discharge nozzle and provide propulsion of the vehicle in the first direction. The reverse mechanism produces a flow entrainment that enhances forward thrust while the reverse mechanism is in the non-deployed position which results in a net thrust gain over the thrust attributed to the discharge nozzle alone. | 08-13-2009 |
20100030411 | MARINE VESSEL CONTROL SYSTEM - A marine vessel control system that includes at least one primary marine propulsory mechanism providing a thrust vector and being movably attached to the vessel. An actuating system is coupled to the at least one primary marine propulsory mechanism manipulating the orientation of the thrust vector. At least one servo control is linked with the actuating system. At least one attitude sensor provides a signal that indicates the attitude of the vessel. A central control computer is operatively coupled to the actuating system, the servo control and the attitude sensor. The central control computer controls the actuation of the at least one primary marine propulsory mechanism's thrust vector in response to the signal from the attitude sensor indicating the attitude of the vessel. The attitude, stability and motion damping and at least one of the pitch, roll and yaw axes of the vessel is controlled. | 02-04-2010 |
20100043691 | TRIM TAB - A trim tab assembly for a watercraft includes a enclosure. A support structure is positioned in the enclosure. At least one trim tab is disposed in the enclosure. The trim tab includes a generally planar top, bottom, side and front surfaces linked by a curved surface defining a wedge shaped body. An actuator is linked to the trim tab pivotally moving the trim tab relative to the enclosure. | 02-25-2010 |
20100054641 | ACTUATOR MOUNT ASSEMBLY - An actuator mounting assembly includes an actuator and a bearing removably attached to the actuator. A bearing plate includes a hole formed therein for receiving the bearing. A bearing mounting plate includes a hole formed therein for receiving the bearing. First and second bearing inserts are removably disposed about the holes formed in the bearing plate and bearing mounting plate. The bearing mounting plate and bearing plate are coupled to retain the bearing and bearing inserts therebetween firming a seal wherein the actuator is angularly movable about the bearing. | 03-04-2010 |
20100221964 | ADJUSTABLE PROPELLER - An adjustable propeller assembly that includes a propeller housing and a drive shaft. A propeller shaft is linked with a propeller. The propeller is linked with a pivotal housing. A coupling member is connected to the drive shaft and propeller shaft. The coupling member pivotally transmits a torque from the drive shaft to the propeller shaft. An actuator is connected to the pivotal housing. The actuator moves the pivotal housing and propeller wherein a thrust vector of the propeller is adjusted relative to the propeller housing | 09-02-2010 |
20110271933 | FORCED INDUCTION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - A forced induction system for an internal combustion engine that includes at least one cylinder and at least one piston that is positioned in the cylinder. Valves are linked with the cylinder that allows ingress and egress of a fluid. At least one accumulation chamber is positioned external relative to the cylinder and accommodates fluid exiting an under piston volume. During a four-stroke combustion cycle of the engine, two charges of fluid from the under piston volume are introduced in an above piston volume during the intake stroke of the engine increasing an efficiency of the engine. | 11-10-2011 |
20110277719 | ROTARY INTAKE AND EXHAUST SYSTEM - A rotary intake and exhaust system for an internal combustion piston engine that includes an engine having at least one cylinder and piston that define a combustion chamber. A crankshaft is coupled to the piston for moving the piston within the cylinder. A cylinder head is positioned to interface with the combustion chamber and includes a combustion chamber transfer port, and bifurcated intake and exhaust passages, called ports or tracts, formed therein. A driven rotatable shaft is positioned in the cylinder head to interact with the combustion chamber transfer port. The shaft includes intake and exhaust ports wherein rotation of the shaft transfers fluids and gases in and out of the combustion chamber. | 11-17-2011 |
20130098283 | TRIM TAB - A trim tab assembly for a watercraft includes a enclosure. A support structure is positioned in the enclosure. At least one trim tab is disposed in the enclosure. The trim tab includes a generally planar top, bottom, side and front surfaces linked by a curved surface defining a wedge shaped body. An actuator is linked to the trim tab pivotally moving the trim tab relative to the enclosure. | 04-25-2013 |
20140190387 | TRIM TAB - A trim tab assembly includes a trim tab and a support structure. The trim tab includes first and second ends. The first end includes a member or a curved surface. The member or the curved surface, when in an extended state, adjusts motion of a marine vessel. The second end attaches to the marine vessel via an attachment device. The member or the curved surface is convex-shaped such that the member or the curved surface curves outward in a direction away from the attachment device. The support structure attaches to the marine vessel. The support structure includes a scraper plate. The scraper plate is adjacent the member or the curved surface. The member or the curved surface moves relative to the scraper plate while transitioning between a retracted state and the extended state. | 07-10-2014 |
20140190388 | Trim Tab Assembly - A trim tab assembly including a hinge assembly and a trim tab. The trim tab includes a wedge-shaped body with a curved surface and a side. The curved surface, while in a deployed state, adjusts pitch, roll or yaw motion of a marine vessel. The curved surface is pivoted about a portion of the hinge assembly when transitioned between retracted and deployed states. A first portion of the curved surface extends below the marine vessel while in the deployed state and deflects oncoming water when a portion of the curved surface is extended below the marine vessel. A second portion of the curved surface is not below the marine vessel while in the deployed state. The hinge assembly is configured to attach to a support structure of the marine vessel rearward of the curved surface. The side extends between the curved surface and the hinge assembly. | 07-10-2014 |
