How many blades make up the TH-73A main rotor assembly?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (C)

The main rotor assembly of the TH-73A is designed with a specific number of blades to enhance performance, stability, and maneuverability. In this case, the TH-73A utilizes a three-bladed rotor system. This configuration is advantageous because it strikes a balance between providing enough lift and reducing vibrations while maintaining efficiency. A three-bladed rotor system also allows for better control and responsiveness during various flight conditions, which is vital for training purposes where handling characteristics are critical. This design choice contributes to the overall operational effectiveness of the TH-73A as a training helicopter, ensuring that students receive a comprehensive learning experience.
