A contra-rotating propeller was patented by F. W. Lanchester in 1907. [9] Some of the more successful British aircraft with contra-rotating propellers are the Avro Shackleton, powered by the Rolls-Royce Griffon engine, and the Fairey Gannet, which used the Double Mamba Mk.101 engine. In the Double Mamba two separate power sections drove one ...
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 ...

Contra-rotating propellers are used. The propellers designed are more efficient than turbo-fans and their cruising speed (Mach 0.7–0.85) is suitable for airliners, but the noise generated is tremendous (see the Antonov An-70 and Tupolev Tu-95 for examples of such a design).

The D-236, an engine with unshrouded contra-rotating propellers, was first investigated in 1979 [3] as the powerplant for the first version of the Ukrainian Antonov An-70. The front propeller was tested on the Antonov An-32 military transport aircraft in 1980, as the An-32's normal Ivchenko AI-20DM engines had about half the rated power of the ...
The ultimate product of a design that began with the Arsenal VG 10 prior to the war, the VB 10 added a second engine behind the cockpit which drove a second propeller, coaxial with and contra-rotating to the propeller driven by the engine in the nose.
