| 20100129228 | TURBINE BLADE PLATFORM TRAILING EDGE UNDERCUT - A gas turbine blade having reduced stresses around a regions where the airfoil training edge joins the platform is disclosed. The lower stresses are achieved due to an undercut region proximate the blade trailing edge being placed in the platform. The undercut region has a compound fillet radius formed from two single and tangent radii where the first radius closer to the airfoil is larger than the second radius such that a ratio of R | 05-27-2010 |
| 20110081250 | Hydro-kinetic transport wheel - A hydrodynamic impulse waterwheel turbine designed to exploit the head of watercourses. The waterwheel is contained within a wheel well mass housing enclosure, which maintains half of said waterwheel out of the water stream, wherein a multiplicity of interlocking inner wheels, with a novel designed of multifaceted cells, uniformly spaced within the periphery and the interior of said waterwheel, will turn in relationship to the waterwheel axis, presenting a new facet of the cell to the incoming water flow as it turns, increasing their efficiency exponentially, referred to as the actual water inflow rate to the plant per unit of time and the actual available head. The space between the cells is maintained vertically and horizontally but the location of the cells are offset in relationship to the cell immediately in front, allowing the free flow of the water throughout the waterwheel maintaining the waterwheel turning at the same velocity of the water stream. | 04-07-2011 |
| 20110142672 | WIND TURBINE ROTOR BLADE WITH A SUCTION SIDE WINGLET - A rotor blade for a wind turbine is disclosed. The rotor blade may comprise a root portion, a tip, and a body extending between the root portion and the tip. The body may include a pressure side and a suction side. Additionally, a winglet may be defined by the body. The winglet may terminate at the tip of the rotor blade and extend inwardly in a direction of the suction side of the body. Further, a bend may be defined in the body such that a portion of the body extends outwardly in a direction of the pressure side of the body. | 06-16-2011 |
| 20110182747 | HUB FIN DEVICE - The present invention discloses a hub fin device for improving the efficiency of a propeller. The hub fin device can include a propeller having a hub and a plurality of propeller blades that extend radially outward from the hub. Each of the plurality of propeller blades has a trailing edge region. A fin can also be included and located in the trailing edge region of at least one of the plurality of propeller blades. The fin extends radially outward from the hub and reduces or eliminates a hub vortex that is normally present during operation of the propeller. | 07-28-2011 |

Jupiter FL USAANM Prakash; ChanderAACI OrlandoAAST FLAACO USAAGP Prakash; Chander Orlando FL USAANM Harris; MelissaAACI OrlandoAAST FLAACO USAAGP Harris; Melissa Orlando FL US - In a gas turbine engine, a flow directing member includes a platform supported on a rotor and includes a radially facing endwall and at least one axially facing axial surface extending radially inwardly from a junction with the endwall. The flow directing member further includes an airfoil extending radially outwardly from the endwall and a fluid flow directing feature. The fluid flow directing feature includes a groove extending axially into the axial surface. The groove has a radially inner groove end and a radially outer groove end, wherein the outer groove end defines an axially extending notch in the junction between the axial surface and the endwall and forms an opening in the endwall for directing a cooling fluid to the endwall. | 01-17-2013 |
| 20130129521 | TURBINE BLADE SKIRT - The disclosed propeller/turbine blade enhancement will be used in the moving fluid kinetic energy conversion field. This turbine blade skirt enhancement to a propeller/turbine bladed assembly will increase the kinetic energy conversion of the assembly on which the enhancement has been made a part of. The disclosed turbine blade skirt will contact and redirect a portion of the moving fluid the propeller/turbine bladed assembly is converting into mechanical rotational energy. The contacting and redirecting the fluid from the least efficient conversion areas of the assembly to the more efficient conversion areas of the assembly increases the amount of mechanical rotational energy obtained from the assembly. | 05-23-2013 |
