The implementation of highly accurate physics calculations has been the main focus of development for Wing42. This effort condenses into our very own physics engine that we called the Prop-o-Tronic physics engine. This module is under constant development and will be updated regularly.

The Prop-o-Tronic technology is featured in our Lockheed Vega 5 and it is responsible for the ultra realistic system simulation of the aircraft. The physics engine consists of multiple sets of algorithms that are based on formulas used in real-world physics an engineering. The engine is still in development, but many parts of the module are already fully implemented, such as:

  • Electrical simulation
    The module includes algorithms to calculate the voltages and currents of any given DC mesh. It utilises the Millman theorem and Ohms law to perform real-time calculations.
  • Fluid dynamics
    Prop-o-Tronic can perform calculations of fluid dynamics in multi-node meshes. It calculates flow rates, kinematic viscosities and resulting pressures using the work of Darcy-Weisenbach, Reynolds, Pascal and others.
  • Thermodynamics
    The physics engine can calculate the heat exchange of two bodies or mediums through three different methods: conduction, convection and radiation.
  • Motion dynamics
    Motion is calculated using Newtonian physics and its differential equations.

The diagram outlines the way the Prop-o-Tronic physics engine can interact with the flight simulator using both, the standard (gauge) interface and simConnect for the data exchange.
