The Tupolev Tu-144 (NATO: Charger) supersonic transport (SST) was the first of the two supersonic passenger airliners to fly. The other one was the Concorde.

The aircraft is unique for its retractable canards, which enable takeoff/landing at speeds not much higher than those of conventional airliners.

FlightGear model

The project was conceived in July 2014 and is active since April 2015. Its goal is to implement accurate flight dynamics and systems of the Tu-144 entirely in JSBSim (and ultimately support testing in standalone JSBSim), as well as a clean and simple visual model.

Current status

As of November 2016, we have:

  • Plausible FDM and control;
  • Reasonable autopilot, based on the documentation for a related system, ABSU-154;
  • Engines and basic systems following POH;
  • Agreement with known flight envelope and centre of gravity in most configurations;
  • Correct multiplayer visual and sounds.

Known issues

When FDM and systems reach sufficient realism, the following problems will be addressed first.

  • External visual model is still unfinished;
  • There are very few instruments in the cockpit, user having to rely on dialogs.
