The “Weight of Wing” in aircraft design refers to the mass of the aircraft’s wings, including their supporting structures, control surfaces, and associated components. The weight of the wing is a critical parameter in aircraft design, as it directly affects the aircraft’s overall weight and balance. Here’s the formula, definition, and SI unit for the Weight of Wing:
Formula for Weight of Wing: The Weight of Wing is typically determined through engineering analysis, measurements, and detailed design calculations. It involves summing up the masses of various components that make up the wings. Mathematically, it can be expressed as:
-
- Weight of Wing: The mass of the entire wing assembly, including its supporting structure and associated components, typically measured in kilograms (kg) or pounds (lb).
- Mass of Wing Structure: The mass of the main wing structure, including the wing spar, ribs, and skin.Mass of Control Surfaces: The mass of movable surfaces on the wing, such as ailerons, flaps, and slats.
- Mass of Wing Attachments: The mass of components that attach the wing to the aircraft’s fuselage or body.
- Mass of Other Wing Components: This may include the weight of fuel tanks within the wings, landing gear components, and other wing-related items.
