A ram air turbine may include an output shaft, a first turbine blade set configured to rotate in a first direction, and a second turbine blade set configured to counter-rotate with respect to the first turbine blade set. The rotation of the first turbine blade set and the counter-rotation of the second turbine blade set drives the output shaft.

Ram air turbine

A fluid accelerator including an outer housing having an inlet end and an outlet end, the outer housing defining a converging nozzle proximate the inlet end. The fluid accelerator may also include an annular ring disposed proximate the inlet end of the outer housing within the converging nozzle, wherein the annular ring has an airfoil cross-sectional shape.

Fluid accelerator

A turbine wheel may include an inner hub having a central axis, an outer ring concentric with the inner hub, and an intermediate ring concentrically disposed between the inner hub and the outer ring, and a plurality of turbine blades extending between the intermediate ring and the outer ring. The turbine blades may be oriented to be driven by a fluid stream flowing through the turbine wheel to rotate the turbine wheel in a first direction about the central axis. In addition, the turbine wheel may further include a plurality of compressor blades extending between the inner hub and the intermediate ring. Also, the compressor blades may be oriented to propel a fluid in a downstream direction when the turbine wheel is rotated in the first direction.

Various embodiments of an airfoil and machines with airfoils are disclosed. The airfoils include a thicker leading airfoil portion and a thinner trailing airfoil portion. In one embodiment, the leading airfoil portion is formed by bending a body of the airfoil back toward itself. In another embodiment, the leading airfoil portion has a solid geometry and includes two elliptic surfaces. To prevent detachment of airflow, the leading airfoil portion includes at least two arc portions or surfaces that act to direct the airflow down to the trailing airfoil portion in a manner that stabilizes vortexes that may form in the region of changing thickness.

Airfoils and machines incorporating airfoils

A golf club head for a driver is disclosed. The golf club head includes a face portion and a rearward end portion. An upward facing surface in a crown portion of the golf club head curves up towards the rearward end portion to keep airflow from separating from the crown portion. A downward facing surface on a sole portion of the golf club includes an airfoil that helps keep air stuck to the sole portion of the golf club head. The airfoil portion extends across a substantial entirety of the width of the golf club head.

An upward facing surface in a crown portion of the golf club head curves up towards the rearward end portion to keep airflow from separating from the crown portion. A downward facing surface on a sole portion of the golf club includes an airfoil that helps keep air stuck to the sole portion of the golf club head. The airfoil portion extends from a toe portion to a heel portion of the golf club head to help maintain smooth airflow across the entirety of the golf club head during a swing.
