KA-52 - How A Military Coaxial Helicopter Works

The Kamov Ka-52 Alligator is an all-weather combat helicopter created by the Kamov Design Bureau.

The Ka-52 is an upgraded version of The Ka-50 helicopter also known as Black Shark.
It is intended to strike low-speed air targets as well as armored and unarmored ground targets.

Most helicopters' main rotors rotate in a clockwise direction, which produces a torque or counterforce in the opposite direction.
In order to counter this rotational torque on the body of the helicopter, which reduces helicopter stability.
The helicopters use a tail rotor that provides the opposing force to push against the torque of the main rotor.
Because helicopters depend so heavily on their tail rotors, any failure of the tail rotor could result in the aircraft losing control and entering an uncontrollable spiral lead.
The coaxial rotor was one of many creative ideas created to fully omit the tail rotor. Helicopters with coaxial rotors have two rotors positioned one on top of the other.
They are driven by coaxial shafts connected to the gearbox.
The two rotors rotate in opposite directions.
The lack of a tail rotor frees the helicopter from needing to transmit torque to it, greatly simplifying the boom design because the torque created by the rotors is not acting on the body.
This makes the Helicopter very maneuverable and suitable for Attack helicopters and carrier base landing.

Due to the aerodynamic symmetry of the helicopter, it can conduct new sorts of combat manueuvres which are the benefits of the coaxial rotor design is enhanced thrust of the main rotor blades and high turn rate.
Combat maneuvers such as flat turns in the direction of the target, sideways motions at high speeds are less seen in heavily armored combat aircraft. one
and deep glides with a high pitch angle of up to 30 degrees or 35 degrees known as vortices are one of the main reason for the advantage of the Co Axial rotors.
