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.

The CoAX 2D/2R was originally known as the FLIP 2 (Fly In Perfection) and is a derivative of the FLIP 1, a conventional helicopter with a main and tail rotor.[1]The CoAX 2D/2R was designed to comply with the European Class 6 microlight helicopter rules, including the category's maximum takeoff weight of 450 kg (992 lb).
Its two coaxial, contra-rotating two-bladed rotors have diameters of 4 m (13.1 ft). The main rotors are both of fixed pitch design, with no articulation in any axis. Steering is accomplished by pivoting the rotor head on a gimbal using a control handle, in a similar manner to a weight shift hang glider. Climb and descent is controlled by ...
The Boeing-Sikorsky team is seen to have an advantage with their large industrial base that may result in wider support from Congress. Their transport helicopters are the most-used in the Army currently. [12] Up to 2013, Sikorsky and partners have spent $250 million on X2 and Raider. [6] The team and aircraft will be separate from the S-97 ...

[1] in the mid-1950s.It later was redesigned for a U.S. Marine Corps requirement for a small personal helicopter that would fulfill an array of roles, including observation, liaison, small unit tactical maneuvers, and which could be dropped to downed ...
The Breguet G.111 or alternatively, G.11E was a French passenger coaxial rotors helicopter flown soon after World War II. Only one was built, development ceasing when funding ran out. Only one was built, development ceasing when funding ran out.
The Ka-26 is eminently useful for civil agricultural use, especially crop dusting. The coaxial main rotor configuration, which makes the Ka-26 small and agile, also results in a delicate airflow pattern under the helicopter, providing a thorough, yet mild distribution of chemicals onto plants.
