The mass of flaps in aircraft design can vary depending on the specific design and aircraft model. Flaps are control surfaces that are part of the wing and are used to modify the lift and drag characteristics of the aircraft during takeoff and landing.
Mass of Flaps (M) is the mass of the flaps in kilograms (kg) or pounds (lb).Volume of Flaps (V) is the volume of the flaps in cubic meters (m³) or cubic feet (ft³).Density of Material (ρ) is the density of the material used to construct the flaps in kilograms per cubic meter (kg/m³) or pounds per cubic foot (lb/ft³).
