How is the TH-73A's main rotor assembly categorized?

• A. Single blade
• B. Dual blade
• C. Four blades
• D. Multi-blade

Answer: (C)

The main rotor assembly of the TH-73A is categorized as having four blades. This design is advantageous for several reasons. Four blades provide improved lift capabilities and enhanced stability compared to rotor systems with fewer blades. They also contribute to reduced vibration levels, which enhances passenger comfort and increases the longevity of the helicopter's components. Additionally, the four-blade configuration is beneficial for performance during demanding maneuvers and operational conditions, making the TH-73A well-suited for training and various mission profiles. The four-blade rotor system strikes a balance between efficiency, stability, and performance, making it an optimal choice for this helicopter's intended use.
