  • Patent number: 11661122
    Abstract: An airflow adjusting apparatus includes a downward airflow generator, a rearward airflow generator, and a controller. The downward airflow generator is configured to generate an airflow, and is disposed at a front edge of a movable body to generate the airflow traveling in downward direction. The rearward airflow generator is configured to generate an airflow, and is disposed at a lower surface of the movable body to generate the airflow traveling in a rearward direction. The controller is configured to perform switching between a lifting-force increase control and a lifting-force suppression control in accordance with a state of the movable body to execute one of the controls. The lifting-force increase control is a control of activating the downward airflow generator and deactivating the rearward airflow generator. The lifting-force suppression control is a control of deactivating the downward airflow generator and activating the rearward airflow generator.

    Abstract: A system and method for the real-time optimization of aircraft fuel economy includes sensors to monitor in-flight performance characteristics, to monitor the status of aircraft control elements during flight, to monitor fuel consumption, and to identify aircraft position information during flight. A processor is coupled to receive information from the sensors. During flight, the processor calculates a current performance level by entering the received information into a predetermined flight model. The processor then determines, based on a comparison of the calculated current performance level with a predetermined expected performance level, a current level of fuel efficiency. Next, the processor determines any parameter changes for improving fuel efficiency. Finally, the processor causes the determined parameter changes to be displayed on a flight deck display. The flight crew may then selectively implement one or more of the determined parameter changes via the flight deck display.

  • Patent number: 8260483
    Abstract: The present invention provides a guidance, navigation, and control method and system for an underground mining vehicle that allow said vehicle to be taught a route by a human operator and then have it automatically drive the route with no human intervention. The method works in three steps: teaching, route profiling, and playback. In the teaching step the vehicle is manually driven by a operator along a route which can consist of an arbitrary sequence of maneuvers including tramming forwards, switching directions, tramming backwards, turning, or pausing movement. During this phase raw data from vehicle-mounted sensors including odometric sensors and rangefinders are logged to a file throughout teaching for later processing. During the (offline) route profiling step, the raw data in the log file are processed into a route profile, and a profile of desired speed as a function of distance along the path.

  • Publication number: 20090071391
    Abstract: A multi segment articulated Surface Effect Ship.Flexible air seals are formed between hull modules with a gas cushion contained between the side hulls under the entire length of the ship. In one embodiment the cushion formed may act as one continuous gas cushion whereby air cushion pressure generated or flowing from a leading car, or modular segment, flows rearward to supply or augment the cushion pressure necessary to support the following modules at the required operational draft. Hull configurations adaptable to the multi-unit, articulated surface effect ship described in the invention include conventional and air cushion assisted catamaran, trimaran and quadramaran designs and configurations.

  • Patent number: 7428939
    Abstract: A flexible skirt-cell system is provided for a hovercraft having a propulsion system mounted to interface with water and a flexible skirt having an upper flexible panel section and a lower flexible finger section. The panel section extends around the bow, stern and two sides of the hovercraft hull and the finger section extends around the hull below the panel section and is connected to the panel section from a forward-abeam location and forward along the two sides and across the bow. Fans create pressurized air that is fed through air ducts to form a pressurized air cushion that supports the hovercraft. Interconnected flexible cells are connected between the panel and finger sections from the forward-abeam locations rearward to the stern. Additional air ducts pass pressurized air from the fan units to inflate the cells, thereby elevating the stern and raising the propulsion system above the water.

  • Patent number: 7231997
    Abstract: An air-based thrust recovery system for use in a powered lift platform utilizing fixed-pitch propellers is provided. The system utilizes an air compressor coupled to the drive motor of the platform and an on-board, high pressure tank for air storage. The fixed-pitch propellers are coupled to the primary drive system with over-running clutches, thus allowing the thrust recovery system to rotate the propellers faster than if driven solely by the primary drive system. Preferably the propellers are surrounded by air ducts. The thrust recovery system uses individually, or in combination, cold air jets mounted at the tips of the propellers, a circulation control system which blows out the leading or trailing edge of the propellers, and one or more perforated tubing segments surrounding at least a portion of the platform's air ducts.

  • Patent number: 7219854
    Abstract: A “wing in ground effect” aerial vehicle includes a wing mounted on a fuselage, and two cycloidal propulsion units for providing lift, thrust and longitudinal control. Additional lift is provided by a lighter-than-air gas such as helium contained in the fuselage. Operationally, the two cycloidal propulsion units and the volume of lighter-than-air gas are concertedly regulated to achieve “wing in ground effect” flight. Importantly, the two cycloidal propulsion units may operate in one of several modes, to include a curtate mode, a prolate mode, and a fixed-wing mode. Additionally, the vehicle may hover. Also, a thruster unit is mounted on the fuselage for providing forward thrust in combination with, or in lieu of, the two cycloidal propulsion units.

  • Patent number: 7051826
    Abstract: A surface effects skimmer vehicle generates a downward air flow into a tunnel under a main hull to lift the main hull off an adjacent surface, and rearward air flows for thrust. The air flows are generated by ducted fans or jet engines, and directed to the rear and/or down by controlling the degree of opening of a Deflector Air Gate (DAG) on the bottom of the main hull. The tunnel includes tunnel edges to contain the downward air flow under the main hull for surface lubrication. The vehicle further includes a rear portion with horizontal and vertical stabilizers to provide air-craft like behavior.
