Flight Mechanics utils :airplane:

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...
