Overview

A library for Kerbal Space Program (KSP) calculation and simulation tools.

All units are mks (meters-kilograms-seconds) and all angles are radians.

Major Classes

Planetoid

  • Encapsulates parameters relating to suns, planets, and moons, such as Kerbal and Mun.

Orbit

  • Encapsulates parameters relating to orbits about a body.

Maneuver

  • Encapsulates parameters for orbit changes.

TODO

  • Refactor planetoid and orbit tests to use a JSON data file from a game dump.

  • Add bielliptic transfer and tests.

  • Build a tool for calculating lead angles: kerbaldyn leadangle kerbin@100a mun

  • Build a tool for outputting body information in standard units: kerbaldyn info minmus

  • Build a tool for calculating the delta-v of hohmann vs various bielliptic transfers: kerbaldyn transfer kerbin@900r minmus

  • Build a tool for listing parts of a type with important specs, sorted in useful ways: kerbaldyn partlist –type liquidfuelengine –sort isp

Notes:

  • Remember that bielliptic transfer high altitudes are theoretically limited by the SOI.

  • Can specify orbits by planet@400a or planet@400r for 400km alt or 400km radius respectively.
