Flight Mechanics in Julia.

Overview

This is a suite for Flight Mechanics written in Julia. The purpose of this package is to supply efficient and validated Julia implementations of common Flight Mechanics calculations.

At the moment, it covers:

• International Standard Atmosphere.
• Transformations between common coordinate systems in Flight Mechanics problems (body, horizon, wind, ECEF) supporting Euler angles and quaternions.
• Kinematics & Dynamics:
  • Rigid solid velocity and acceleration fields.
  • Angular kinematic equations.
  • Steiner theorem:to determine the moment of inertia of a rigid body about any axis.
  • Trimmer constrains for leveled flight, climbs and turns.
• Anemometric functions (tas, cas, eas, dynamic pressure).
• ECEF (Earth Centered Earth Fixed) <–-> LLH (Latitude Longitude Height) conversions.

What's new

v0.1.2

New

• Ellipsoid type with some common ellipsoids such as WGS84.
• Transformation (ecef2llh) from ECEF (Earth Centered Earth Fixed) to LLH (latitude, longitude, height) and viceversa (llh2ecef) given the reference ellipsoid.
• Rotation (horizon2ecef) from local horizon to ECEF axis and vicecersa (ecef2horizon).

Enhancements

• coordinated_turn_bank(ψ_dot, α, β, tas, γ, g) now accepts gravity as optional argument.

v.0.1.1
