2. Coaxial-rotor aircraft - Wikipedia

   en.wikipedia.org/wiki/Coaxial-rotor_aircraft

   A coaxial-rotor aircraft is an aircraft whose rotors are mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau .

   Quadcopter coaxial – OnyxStar FOX-C8 XT Observer from AltiGator. In order to allow more power and stability at reduced weight, a quadcopter, like any other multirotor can employ a coaxial rotor configuration. In this case, each arm has two motors running in opposite directions (one facing up and one facing down). [citation needed]

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 ...

5. Contra-rotating - Wikipedia

   en.wikipedia.org/wiki/Contra-rotating

   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 ...
