Ace the TH-73A Systems Exam 2026 – Soar to Success with Confidence!

The tail rotor of the TH-73A is indeed a semi-rigid flapping design. This design allows for some flexibility, enabling the blades to flap, which helps to control the torque and provides better stability during flight. In a semi-rigid system, the rotor blades are connected to a central hub with limited freedom of movement, which facilitates the necessary aerodynamic adjustments while maintaining structural integrity. This characteristic is crucial in rotary-wing aircraft, as it enhances performance and maneuverability, particularly during various flight conditions. The design contributes to the efficient operation of the tail rotor and overall handling of the helicopter, making it an advantageous choice for the TH-73A's flight capabilities.
