The Tupolev Tu-144 (NATO: Charger) supersonic transport (SST) was the first of the two supersonic passenger airliners to fly, the other one being the Concorde. Tu-144's unique retractable canard allows the elevons to function as flaperons, bringing the takeoff/landing speeds closer to conventional airliners and allowing to use the same airports. It was one of the last commercial aircraft with a braking parachute, due to difficulties in thrust reverser development.
The Tu-144D addon for FlightGear has been developed by Michael Danilov since April 2015 to accurately model the latest long-range variant of the aircraft, Tu-144D model 09 from 1981. It can be installed with the QT launcher hangar URL: https://gitlab.com/mdanil/Tu-144D_hangar/raw/master/catalog.xml.
The highlights, as of August 2021, are:
- FDM based on DATCOM and some literature data, that agrees with normal flight perf in the whole fuel-payload domain.
- FCS, engines, systems and most instruments able to follow the Flight Manual[1]. Note that there will be differences because the Flight Manual is for an old variant of Tu-144 sans D.
- Automatic management of fuel and center of gravity for each stage of flight.
- All normal and some emergency procedures documented in the Checklists window, most also working as Tutorials.
- In-sim calculator for fuel, payload, center of gravity and change of flight levels.
- Detailed visual almost fully synchronized over MP and supporting the latest Compositor features. Adapted from from Nikita Konstantinov's FSX add-on[2] with improvements and optimizations.
- Automated copilot and engineer doing callouts, performing their tasks during landing and take-off, as well as some on-demand actions such as instrument setting or engine startup.
