In aircraft design, the density of an aircraft structure have a specific formula or definition as it would for fluids or gases. Instead, the density of an aircraft structure is a physical property that refers to the mass of the structure per unit volume. It can be calculated using the following formula:
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- P = Pressure of the fluid (in pascals, Pa)
- R = Specific gas constant for the fluid (in J/(kg·K))
- T = Temperature of the fluid (in kelvin, K)
