What type of rotor system does the UH-60A utilize?

The UH-60A Black Hawk helicopter is designed with a single main rotor system. This type of rotor configuration consists of one main rotor blade that provides the necessary lift and thrust for flight. The design is complemented by a tail rotor, which is used for anti-torque and to maintain directional control.

This single main rotor system is advantageous as it simplifies the mechanical design and reduces weight, making the helicopter more agile and easier to maintain. It also allows for a higher power-to-weight ratio, enabling the UH-60A to perform effectively in various operational conditions.

In contrast, coaxial rotor systems involve two rotors mounted on the same axis that rotate in opposite directions, which is not utilized in the Black Hawk. Similarly, a dual rotor system typically refers to helicopters with two main rotors mounted one above the other or on separate axes, which is a different design. Multi-blade rotor systems, while they can describe configurations with numerous blades, more commonly refer to rotorcraft that may not employ the single main rotor method that the UH-60A uses.
