The '''Tupolev Tu-144''' (NATO: Charger) supersonic transport (SST) was the first of the two supersonic passenger [[:Category:Airliners|airliners]] to fly. The other one was the [[Concorde]].
The Tu-144 addon for FlightGear has been developed by Michael Danilov since April 2015 and aims to accurately model the latest, long-range, variant of the aircraft (Tu-144D). It can be installed with the [[FlightGear_Qt_launcher|QT launcher]] using this hangar URL: https://gitlab.com/mdanil/Tu-144_hangar/raw/master/catalog.xml


The aircraft is unique for its retractable canards, which enable takeoff/landing at speeds not much higher than those of conventional airliners.
The highlights, as of December 2020, are:


== FlightGear model ==
* [[DATCOM]] FDM agrees with normal flight perf in the whole range of fuel and payload.
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 ==
* FCS, engines, systems and most instruments follow the POH.
As of September 2015, we have:


* Plausible FDM and control;
* Normal flight's procedures are fully covered in Checklists window, most of them also work in Tutorials.


* In most configurations the aircraft follows manufacturer's flight envelope and centre of gravity;
* Detailed visual, adapted from from Nikita Konstantinov's FSX add-on with slight improvements, almost fully syncs over MP.


* It is damped well enough for default autopilot to control;
* Automated crew reduces the simulation-related workload by performing some of the copilot and engineer tasks on command, reading some instruments and doing some actions during landing and RTO.


* The visual and all animations display correctly in multiplayer.
* Both realistic autostart and [[State_Overlay_System|state overlays]] have been implemented, allowing for quick testing and debugging.
 
== Known issues ==
Among many other things that were rushed to test the FDM sooner – and, now that it works, need to be redone more thoroughly – the following are most noticeable and will be addressed first.
 
* Empty cockpit, with user having to rely on HUD and property displays;
 
* Unelegant hydraulic and electric systems;
 
* No sounds in multiplayer.

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 brings its takeoff/landing speeds close to those of conventional airliners, allowing to use the same airports.

The Tu-144 addon for FlightGear has been developed by Michael Danilov since April 2015 and aims to accurately model the latest, long-range, variant of the aircraft (Tu-144D). It can be installed with the QT launcher using this hangar URL: https://gitlab.com/mdanil/Tu-144_hangar/raw/master/catalog.xml

The highlights, as of December 2020, are:

  • DATCOM FDM agrees with normal flight perf in the whole range of fuel and payload.
  • FCS, engines, systems and most instruments follow the POH.
  • Normal flight's procedures are fully covered in Checklists window, most of them also work in Tutorials.
