Classification of Aircraft

Lighter-than-air (Aerostats)

Lighter-than-air systems are the flight systems deriving a significant amount of their lift from the buoyancy effects related to lighter than air gases like hydrogen, helium and methane. Contrary to fixed-wing aircrafts LTA systems are associated with minuscule fuel consu...

    Airfoil & Wing

  • Geometric Angle of Attack (α): The angle between the chord line and the common reference line (often the horizontal axis of the aircraft).

  • Induced Angle of Attack (α_i): The angle by which the local airflow is deflected (downwash) compared to the free-stream velocity.

    Compressible Flow

    Before using the calculator, ensure availability of the following parameters:

    1. Temperature, T (Kelvin, K)

    2. Pressure, p (Pascal, Pa)

    3. Velocity, V (meters per second, m/s)

    4. Gas Constant, R (J/kg·K)

    5. Ratio of Specific Heats, γ

      After calculation, the following outputs will be displayed:

      1. Density (ρ...

    Basic Fluid Mechanics



    As I went on, still gaining velocity, the palpitation of night and day merged into one continuous greyness; the sky took on a wonderful deepness of blue, a splendid luminous color like that of early ...
