The “Weight of Airframe” in aircraft design refers to the mass of the aircraft’s main supporting structure, excluding other major components like wings, engines, and landing gear. The airframe includes the fuselage, tail section, and any other structural elements that make up the aircraft’s framework. Here’s the formula, definition, and SI unit for the Weight of Airframe
Formula for Weight of Airframe: The Weight of Airframe is typically determined through engineering analysis, measurements, and detailed design calculations. It involves summing up the masses of various structural components that constitute the airframe. Mathematically, it can be expressed as:
- Weight of Airframe: The mass of the aircraft’s main supporting structure, excluding other major components, typically measured in kilograms (kg) or pounds (lb).
- Mass of Fuselage: The mass of the aircraft’s main body, which houses the cockpit, cabin, and cargo compartments.Mass of Tail Section: The mass of the rear section of the aircraft, which includes the vertical stabilizer and horizontal stabilizer.
- Mass of Other Structural Elements: This may include the weight of structural components that are not part of the wings, engines, or landing gear.
