Flight Mechanics utils ✈️

⚠️ This package is in its initial development phase 🚧

This package is intended to provide utils for Flight Mechanics computations. It runs on julia ≥ 1.0

  • International Standard Atmosphere: get pressure, temperature, density, sound velocity for a given altitude.
  • Conversion between different coordinate systems:
    • body
    • horizon
    • wind
    • ECEF
    • llh (latitude, longitude, height) over various ellipsoid models
  • Quaternion and euler angles conversions
  • Anemometry:
    • conversion between tas, cas, eas.
    • velocity calculation from airspeed indicator (ASI) pressure difference
    • dynamic pressure calculation (compressible and incompressible cases)
    • tas, alpha, beta from body velocity
  • 6 DOF Dynamic fixed mass models:
    • Flat Earth Euler angles
    • Flat Earth quaternions
    • Ellipsoidal Earth ECEF model quaternion
  • An experimental version of the simulator has been started. At the moment it comprises:
    • C310 aerodynamics model obtained from JSBSim with an oversimplified engine model.
    • F16 aerodynamics and engine (except for engine lag) model from ([1]).
    • A preliminary version of the trimmer able to trim both aircrafts and validated for F16 with text book examples.
    • Some base models serving as a for the development of the simulator: state, position, attitude, aerostate, mass, propulsion...
