Which component helps absorb vibrations during flight?

• A. Pitch change link
• B. Sliding sleeve assembly
• C. Vibration absorbers
• D. Intermediate gearbox

Answer: (C)

The component that helps absorb vibrations during flight is the vibration absorbers. Vibration absorbers are specifically designed to mitigate excessive vibration that may occur in various systems, including those in aircraft. By absorbing and dampening the unwanted vibrations, these components help enhance the longevity and performance of other mechanical parts and improve overall flight stability and comfort.

In the context of a lifting system, the use of vibration absorbers is critical as they prevent the transfer of vibration to other components, thereby protecting sensitive systems. They play a crucial role in reducing fatigue and wear, leading to safer operations and a higher level of efficiency.

The other components, while important in their respective roles, do not primarily focus on the absorption of vibrations. For example, the pitch change link is part of the control system that allows the adjustment of blade pitch, which affects lift and drag but does not directly manage vibrations. The sliding sleeve assembly is more related to engagement mechanisms within gear systems, whereas the intermediate gearbox is involved in transferring and modifying power from the engine without a primary focus on vibration absorption.
