How much does each propeller blade typically weigh?

The weight of a propeller blade can vary significantly based on its design, size, and material, and the specific application of the propeller. A typical jet propulsion engine or large aircraft propeller blade generally weighs around 4,300 pounds. This weight is a result of the robust construction required to withstand the stresses and forces experienced during operation. The materials used, typically including composites or alloys, are engineered to ensure strength and durability while still keeping the weight manageable for aircraft performance.

While other options may represent weights of propeller blades in different contexts or applications, such as smaller engines or specialized setups, the 4,300-pound measurement is in line with standard weights for larger aircraft propeller blades commonly found in commercial aviation, making it the most accurate answer among the choices provided.
