- "..The end of the Cold War gave rise to an unprecedented opportunity for the United States and Russia to collaborate in a joint aeronautical flight research program. In 1993 a United States-Russian Joint Commission on Economic and Technological Cooperation chaired by then U.S. Vice President Gore and Russian Prime Minister Chernomyrdin, aggressively pursued areas of beneficial technical interchange between the two countries.
At the time, NASA and U.S. commercial aviation industries were heavily engaged in a High-Speed Research (HSR) program to further develop Supersonic Transport (SST) aircraft technologies.
The goal of the HSR program was to posture the U.S. in a lead position toward the development of a second-generation SST aircraft. Russia's Tupolev Aircraft Design Bureau had proposed as early as 1990 that a Tu-144 SST could be used as a flying test-bed in support of the HSR program. Given encouragement from the Joint Commission, a team of senior NASA and U.S. industry aviation specialists developed a prioritized group of flight experiments and worked with a corresponding senior team from the Tupolev Design Bureau to understand modifications that would have to be made to the Tu-144 to conduct those experiments. These activities were the genesis of the Tu-144LL Supersonic Flying Laboratory used in the joint research program.
Twenty-seven research flights of the Tu-144LL were conducted over a two-year time period with apparent ease. The grace and beauty of the airplane masked the very extensive amount of effort that was required by Tupolev to re-engine it for the research flights. Further, the development, implementation, and operation of an instrumentation system that could measure nearly 800 parameters required by the experiments was another task of significant difficulty. The six thousand-mile distance between the U.S. experimenters and the airplane contributed to the difficulties of the instrumentation task. Three evaluation flights accomplished by U.S. pilots in September 1998 highlighted U.S. participation in the flight program. These flights allowed two NASA pilots to gain hands-on experience with the operation of a truly historical airplane operating as an updated test-bed for advanced technologies.
The Tu-144LL program was a resounding success for the U.S. HSR program and the Joint Commission. Seven flight and two ground-based experiments yielded flight data that greatly enhanced the supersonic flight databases available to U.S. and Russian aeronautical engineers. Propulsion, aerodynamic, structural heating, structural acoustics, ground effects, and handling qualities data from the experiments were eagerly assimilated into the program's information database. In March 1998 the Joint Commission recognized the program as "A model for U.S. and Russian government-business partnerships in the development of advanced technologies."
Upon completion of all of the programmed objectives, the TU-144LL aircraft was again relegated to a state of inactivity. Cancelation of the U.S. HSR program in 1999 resulted from the fact that an economically viable SST could not be envisioned near enough to further justify U.S. industry commitment. Russian economics were still severely depressed at that time from political change in Russia following the collapse of communism. .. "

Данный самолет был выбран из четырех Ту-144, сохранившихся в состоянии пригодном для полетов. Силовая установка была подвергнута радикальной переделке. На Ту-144ЛЛ двигатели РД-36-51А разработанные Колесовым П.А. были заменены форсированными турбореактивными двухконтурными двигателями НК-32-1, применяемыми на стратегическом бомбардировщике Ту-160. Использование данных двигателей позволило повысить скорость с М=2,15 до М=2,3. Для регистрации параметров и экспериментальных данных для подтверждения летной годности на самолете установили новую систему регистрации данных "Дамьен". Ту-144ЛЛ был буквально напичкан термодатчиками и датчиками трения обшивки, давления, аппаратурой измерения параметров аэродинамического пограничного слоя.
Literally came back to watch the Tu-144 video you made and I am greeted with this - made my day!
Amazing aircraft! Not bad for 60-70s technologies!
This one is quite different plane than those in 60-70. As you can see also engines are new, from tu-160 , reliable and more powerful. This was the beginner for bomber, it died and now revived thanks the military use 😁
@@masakeris so that means most things other than avionics and stuff were soviet?
@@Yessir1506 no, you cant take it this way. take it the same way as first 747 and 747-400.
Смотрю и слёзы наворачиваются столько труда и...
хотя понимаю что в качестве пассажира он дохода не приносил (как и Конкорд) полёты для престижа страны
но в качестве ЛЛ он же мог еще долго подыматься в воздух...
Музончик как всегда клевый
Built it again❤️❤️❤️🇷🇺
Yes i hope tu-144 back again
They still exist. Why would you need to rebuild it?
спасибо
была Страна....,

Pěkný stroj
Where is this aircraft today? At some museum?
It is on open view stand near Zhukovsky town entrance (literally next to highway)
Hallochen
Besser.!! Als die Concorde.!!! 🇷🇺👍👍
espionnage russe du concorde . vive la france .le notre etait beau
@@micheltoullec2858Tu-144 took off before your Concorde. Study the history of aviation. Russian designers were no dumber than French and English ones
Ещё одни "галоши"
Ужасные галоши делал СССР. Разве Ту-144 или Буран можно надеть на ногу? Вот и я о том же. Не галоши, а черт-те что, самолеты какие-то, ракеты))
❤️🇷🇺❤️

NASA could have hired a Concorde for about 10% what they paid Russia for this copy and failure that crashed so often it was used as a freighter.
But of course that would have meant going cap in hand to the Brits. So they went to the Russians!
MURICAAAA .... 😂
Your comment literally just obliterated my whole braincell colony. I think the tupolev cost 10% less than Concorde tho, totalled with the tu-160 engines (which is an engine that can be found off the shelf) and the modifications it had.
@@Yessir1506 At the time the Tu-144 was not even flying and why it cost NASA so much money to get it back (safely) into the air while Concorde was in full service use. The Tu-144 even in LL version did nothing the Concorde was not already doing.
And as I recall Olympus engines were still available ...
@@1chish Also what makes you think that America has always been against Concorde? If this is the case, Boeing would still continue building the B2707. I reckon the tupolev is safe enough to fly in the air without its crappy old engine lmfao
@@Yessir1506 Where exactly did I suggest that "America has always been against Concorde?". That is not what I wrote at all.
I made the point that the Tu-144 was an abject failure and totally unsafe while Concorde was freely available and flying safely (the safest airliner ever built). And why I questioned NASA putting millions of US taxpayer dollars into the Tu-144.
Americans loved the Concorde and turned out just to watch it. Any antipathy came from vested pro US industry political interests.
@@1chish Well this thing is NOT meant for commercial service so they don’t need to spend too much money to make it safe enough for regular people to fly
