20060210399 - Turbine cooling vane of gas turbine engine: The present invention is intended to provide a cooled blade of a small gas turbine engine which can enhance cooling performance without increasing an amount of cooling air although it is in a simple configuration. A cooled turbine blade is provided with a cooling passageway 12 formed inside thereof, making...

20060210400 - Wind powered electric vehicle/conversion: There is presently no electric vehicle operating in the United States which does not require a power source outside the vehicle to charge the batteries. All previous electric vehicles require some form of connection to an outside power source to charge the batteries. My idea of using a spiral wind...

20060210401 - Ceiling fan blade: A ceiling fan blade is disclosed that is twisted rather than flat and has a graduated dihedral. The dihedral is provided for a wider distribution of divergence of air in the space beneath the fan. The blade (10) is demarked to have three sections which include a mounting section (11)...

20060210402 - Methods and apparatus for assembling rotatable machines: Methods and systems for ordering blades in a rotatable machine is provided. The method includes receiving at least one geometric parameter measurement of each blade in a row of blades, determining a root sum squared value of a difference of a selected one of the received geometric parameter measurements between...

20060204363 - Centrifugal blade unit of a cooling fan: A centrifugal blade unit of a cooling fan at least comprises a wheel hub and a plurality of fan blades connected around the circumference of the wheel hub, each having a first blade section and a second blade section that are either connected or bifurcated. Thereby, a reversed flow of...

20060204364 - Disbond resistant composite joint and method of forming: A disbond resistant multi-laminate composite product is provided having, a first member; a second member of composite material bonded to the first member; a third member of composite material bonded to at least the second member and being so positioned and arranged such that when the second and third members...

20060198732 - Non-articulated rotor and rotorcraft comprising a rotor of this type: A hingeless rotor, in particular for a rotorcraft, comprising: a rotor head, a rotor mast having a rotor axis, a torque-transmission element nonrotatably joined to the rotor mast, at least one rotor blade, and a rotor-head-side rotor-blade connector having a centrifugal-force-discharging blade connector loop, which loop encircles the rotor axis...

20060198733 - Marine propeller drive: A marine propeller drive (1) for boats, including a gearbox (10) for a motor transmission and an associated impelling propeller (12). The propeller (12) is provided with a propeller hub (14), the main peripheral cross-section dimension (A) of which is less than the main peripheral cross-section dimension (B) of the...

20060198734 - Manufacturing method for obtaining high-temperature components for gas turbines and components thus obtained: A manufacturing method for obtaining high-temperature components (10) for gas turbines, which comprises at least incorporation of an element or insert (14) in a main body (12) of the component (10), this element or insert (14) having mechanical properties able to withstand stresses to which said component (10) is subject...
