What component is essential for effective operation of the blade pitch?

• A. Anti-erosion strip
• B. Pitch change link
• C. Vibration absorbers
• D. Blade hinges

Answer: (B)

The pitch change link is crucial for the effective operation of the blade pitch because it directly connects the blade to the pitch control system, allowing the angle of the blades to be adjusted relative to the airstream. This adjustment is essential for optimizing the lift and drag characteristics of the blades during operation, particularly in rotorcraft and wind turbine applications. By altering the pitch, it is possible to manage the performance of the lifting system efficiently, increasing or decreasing lift as necessary in response to changing flight conditions or power requirements. Other components, such as anti-erosion strips, vibration absorbers, and blade hinges, play important roles in the overall functionality and durability of the blades but are not directly involved in changing the pitch. The anti-erosion strip protects the leading edge of the blades from wear, vibration absorbers reduce resonance and vibrations that could compromise structural integrity, and blade hinges allow for some movement of the blades. However, none of these elements are responsible for the critical adjustment of pitch that the pitch change link facilitates. Hence, the pitch change link is the essential component for effectively managing blade pitch.
