A propeller formed along the lines of a vortex, i.e. a Fibonacci spiral projected onto a surface formed by a square hyperbola. Fluid flows evenly along the length of the propeller with less turbulence allowing it to operate at a higher pitch without stalling and resulting in reduced power requirements for a given flow rate. The underlying geometric shape of a vortex is an equiangular logarithmic spiral also known as golden spiral or Fibonacci spiral as is often found in natural objects ranging from sea shells to spiral galaxies. When viewed three dimensionally, the fluid flow in a vortex can be drawn as a projection of a golden spiral onto a surface of revolution of a square hyperbola where the vertex is equal to one and the focus is equal to the square root of 2.
