Gears are precision-machined components whose contact surfaces have been hardened. Gears are manufactured in units and can be manufactured to a wide range of accuracy standards. The American Gear Manufacturers Association lists these requirements in their publications. Propeller design and the ability and thrust coefficients are past the scope of this text. But note that the power absorbed will increase because the cube of the rpm and the fifth power of the diameter. If we plot a typical engine energy curve towards a propeller demand curve, we see the data in Chart 1.
