In the Aerofly FS 2 there are a handful of different engines to propel an aircraft. There are engines that drive propellers through a driveshaft and there are jet-engines that directly create a thrust.

Propeller Propulsion

A propeller in the Aerofly FS 2 is usually connected to a rigidbody object. That Body is then rotated around a jointmulti by a drive shaft torque connection. So in short: the engine acts a torque upon the driveshaft which turns the propeller that then creates thrust based on its rotation speed, pitch and airfoil.

In the Aerofly FS 2 there are a couple of engines to choose from:

See the guide to turbo engine components for more detail.


Jet stream engines compress air, mix it with fuel, burn it in a combustion chamber and accelerate the hot gases through turbine blades. There are numerous ways to create such an engine and each has their own characteristics. In the Aerofly FS 2 the following jet stream engines are implemented:

  • modular turbo engines for high by-pass-ratio turbofan engines used for airliners like the A320, B747 and low by-pass-ratio engine for jet trainers like the MB339 alike.
  • turbofan, turbojet legacy engines with simplified simulation (usage will be faded out over time).
  • jet_engine afterburning turbojet engine used in fighter jets like the F15E or F18.

See our guide to modular turbo engines for more detail.

Rocket Engine

Rocket Engines are currently only partly implemented. The rocketengine class is still recognized but currently broken (as of today, 23rd of Jan. 2017). It might be re-added later, please contact us if you need this type of propulsion for your project. Here is a pretty image of a Laval nozzle in the mean time :D
