The load imposed on rotor blades is defined as the helicopter's total weight divided by the combined area of all rotor blades. Which term describes this?

• A. Blade Loading
• B. Blade Span
• C. Blade Track
• D. Blade Root

Answer: (A)

Blade loading is the weight the rotor blade must support per unit area of the blade. It’s found by taking the helicopter’s total weight and dividing it by the combined area of all rotor blades. This measure shows how heavily the blades are loaded in terms of their surface area, which directly affects structural stresses, vibration, and the power required for hover or ascent. Higher blade loading means each square foot (or square meter) of blade carries more weight, leading to greater bending loads and potentially lower aerodynamic efficiency unless the blade area is increased or power is raised. The other terms describe different blade characteristics: span is how long each blade is, blade track refers to the blade-tip path during rotation, and blade root is the portion of the blade near the hub.
