About AEHS

Propellers convert engine power into thrust by accelerating a column of air.  Even the earliest wooden propellers used by the Wright Brothers were marvels of efficiency and ingenuity. Over time propellers continued to improve. Better materials made them lighter and stronger. Controllable blade pitch made them more versatile and improved performance of the aircraft using them.
