摘要： A jet pump assembly includes a marine engine, a jet drive and a shield adapted to be secured to a transom of a watercraft. The shield has arms to which the marine engine is secured and legs to which the jet drive is secured, the arms and legs extending in opposite directions. The shield has a flange adapted to be secured to the transom of the watercraft. The shield covers an opening in the transom through which the jet pump assembly is passed during assembly. A gasket between the shield and transom prevents water from entering the watercraft.

摘要： A rechargeable robotic pool cleaning apparatus having a first water pump for providing a downward thrust force, a second water pump for providing at least a rearward thrust component, and a third water pump for providing at least a forward thrust component, the apparatus being buoyant when the pumps are not activated and including adjustable flap valves, baffles and nozzles to alter the outflow direction of at least some of the jet streams of water produced by the pumps so as to produce any one or more of a vertical, forward, rearward, and sideward thrust component depending upon the positioning of the baffles and/or nozzle members. At least one main controller is electronically coupled to a rechargeable power source for controlling the operation of the pumps in various combinations for moving the apparatus both vertically and horizontally in the body of water.

摘要： A method and device for adding special substances to the gaseous outflow of the jet engine in order to create a “virtual wall” of increased pressure zone behind the jet engine nozzle which can serve as a support for the jet engine gas outflow to push against, thus increasing the thrust power of the jet engine. This increase in acceleration power results in the accelerated movement of the jet engine equipped vehicle or higher fuel efficiency. A device that adds the special substances to the gaseous outflow is proposed. Characteristics of the special substances, which if added into the jet engine gaseous outflow may create a “virtual wall” of increased pressure zone behind the jet engine, are proposed.

摘要： A fan variable area nozzle (FVAN) includes a flap driven through a cable which circumscribes the fan nacelle. The cable is strung through a multiple of flaps to define a flap set of each circumferential sector of the EVAN. An actuator system includes a compact high power density electromechanical actuator which rotates a spool to deploy and retract the cable and effectively increase or decrease the length thereof between the spool and a fixed attachment to increase and decrease the fan nozzle exit area.

摘要： A quiescently flush resilient portion of a water jet exit channel that distends under controlled fluidic pressure to narrow the flow channel to trade off power for speed in a water-jet-powered watercraft and/or to suppress impeller cavitations during standing starts. The resilient portion may be a continuous annular portion or may be segmented for thrust vectoring. The resilient portion may be built into a water jet exit channel or may be in an add-on nozzle that can be attached to the water jet exit channel, especially for aftermarket improvements. The control system, the water jet exit structure, the water jet, and the watercraft and included. A resilient ring with top and bottom radially outwardly extending flanges mounted on a rigid ring and compressed within a canister between an annular canister floor and a compressive annular cap may provide the plenum and resilient portion of the water jet exit channel.

摘要： Variation in the available mixing plane areas in an exhaust arrangement of a gas turbine engine enables alteration and configuration for better thermal cycle performance of that engine. A shaped centre fairing is associated with an exit nozzle and a bypass duct such that channels between the fairing, nozzle exit and duct can be adjusted to change the available areas. Such variation is achieved by relative axial displacement, typically of the exit nozzle using an appropriate mechanism.
