Learn how contra-rotating and coaxial propellers enhance aircraft performance by maximizing engine power through dual, counter-rotating propellers driven by advanced gear systems.

Aircraft with contra-rotating or coaxial contra-rotating propellers—typically powered by a single high-output piston engine or turboprop—utilize maximum engine power to drive a pair of coaxial propellers that spin in opposite directions. These two propellers are mounted one behind the other, with power transmitted through a planetary or spur gear system. While "contra-rotating propellers" and "counter-rotating propellers" are sometimes used interchangeably, the latter term more commonly refers to separate, non-coaxial propellers mounted on distinct shafts that rotate in opposite directions.
