As the length of the blade increases, how does the width of the tip change?

• A. Narrower and thicker
• B. Wider and thinner
• C. Remains constant
• D. Wider and thicker

Answer: (D)

In the context of blade design, as the length of the blade increases, it typically leads to the widening effect at the tip due to the structural and aerodynamic requirements of a longer blade. This increase in width at the tip is essential for maintaining stability and strength throughout the blade. Longer blades are often designed to handle greater forces and to provide better performance, particularly in applications such as wind turbines or aircraft wings, where a wider tip can help in efficiently managing airflow and reducing drag. The concept that a blade would also become thicker at the tip while increasing in length supports the notion of improving structural integrity. A thicker blade tip can resist bending and deformation better, which is crucial when the blade is subjected to higher operational loads. Thus, the design principles governing blade dynamics and aerodynamics lead to the conclusion that with longer blades, the tips tend to become wider and thicker to enhance performance, safety, and efficiency.
