Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
Contra-rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque. Examples include some aircraft propellers , resulting in the maximum power of a single piston or turboprop engine to drive two propellers in ...
Counter-rotating propellers (CRP) are propellers which turn in opposite directions to each other. [1] They are used on some twin- and multi-engine propeller-driven aircraft. The propellers on most conventional twin-engined aircraft turn clockwise (as viewed from behind the engine). Counter-rotating propellers generally turn clockwise on the ...

A contra-rotating vaned spinner ahead of the main spinner both powers a microprocessor and delivers data to instruct the blades to be adjusted automatically. The V-Prop is an automatic self-powering electronic variable-pitch propeller developed by Silence Aircraft, [1] the manufacturers of the Silence Twister [2] single-seat elliptical-winged ...
In 1982, the weekly aviation magazine Flight International defined the propfan as a propeller with 8–10 highly swept blades that cruised at a speed of 390–480 knots (450–550 miles per hour; 720–890 kilometres per hour), [4] although its definition evolved a few years later with the emergence of contra-rotating propfans.
