![]() | A fact from this article was featured on Wikipedia's Main Page in the On this day section on December 26, 2010. |
At the end of Engines it says "The Kolesov RD-36-51 had an unusual variable con-di nozzle for the nozzle pressure ratios at supersonic speeds. Without an afterburner there was no variable nozzle already available. A translating plug nozzle was used.".
And, Did the Tu-144D need afterburner during Mach 2 cruise (as with the NK-144 engines on the Tu-144S) ? - Rod57 ( talk) 17:44, 1 July 2023 (UTC)
As far as I can make out, the most important model was the Tu-144S. Nine of these were made and they were the only ones used for commercial passenger services.
However the specifications at the bottom of the article are for the later Tu-144D.
I think it would be interesting to have the Tu-144S specifications, which were quite different. 88.87.126.220 ( talk) 08:05, 21 July 2023 (UTC)
A template I added to "Failure to acquire western technology" was removed by an IP, which was probably a good call. I'd like to preserve the reason from the removed template here as the section could use an improvement if a source with more details about French-Soviet collaboration emerges:
"This section appears to entirely rely on a single Aviation Week article as cited in Moon, 1989. The aircraft designers describe the plans for bi-directional exchange in technology between Tupolev and Aerospatiale, which were never implemented due to both Concorde and Tu-144 production ending. According to them, it was a result of a permanent workgroup set as a part of the technology exchange within the French-Soviet Aviation Industry Group, rather than a one-off request to fix the airplane before the Olympics [as interpreted by Moon]. Aviation Week mentions the existence of the group as well, but unfortunately doesn't offer any more details of its activities overall." PaulT2022 ( talk) 11:31, 20 October 2023 (UTC)
It has long been claimed that the Tu144 relied heavily on Soviet espionage yet this article presents a very different story, excising the widely-held view in the west that ‘Concordski’ was substantially the result of IP theft. Two spies miles in particular have been posited and in November 2023 the UK’s Channel 4 TV carried a documentary naming Ivor James Gregory as Agent Ace, the spy revealed by Soviet defector to have been stealing secrets from Concorde programme, including complex technical information from the engine manufacturers, Rolls-Royce. Source, The Times, 24 November 2023 176.25.29.186 ( talk) 12:35, 24 November 2023 (UTC)
intelligence analysts and some Soviet defectors have warned that the KGB seriously exaggerated the significance and number of its contacts and operations to impress the Soviet leadership – and increase its budget
I think it is misleading to use the TU-144D specifications as the primary specs. People will inevitably compare passenger TU-144s with Concorde and come away with a false comparison. The TU-144D was a freight only aircraft and only a couple of TU-144D were constructed and were very short-lived. The in-service TU-144S specifications should be used.
