Sure, except it wasn't. You won't find a single serious book on the Concorde making any such claim.
Why would I be reading books about Concorde to learn about the internal workings of the Tupolev design bureau? Look at the prototype Tu-144, not the production one, and you'll see that, for all the commercial electronics the Soviets were missing, a Xerox machine wasn't one of them. The ogival delta was a novelty when Sud Aviation showed it on the concept for the Super Caravelle
a year or so before Tupolev showed their SST concept
and if you discount being "inspired" by the French, it seems an odd choice for Tupolev in the light of other developments both within OKB-156 (e.g. Tu-125) and other bureaux in the late 1950s. If Tupolev had come up with that plan form based on their own work, they are likely to have got the camber right, but they didn't. Also, Sud Aviation and its successor Aerospatiale were under constant espionage attack from the Soviet Union. The eventual answer is, of course, buried in the secret archives, and maybe only the memories, of the Tupolev bureau, but the circumstantial evidence all points to Tupolev starting the project as a Super Caravelle knock-off before it became, in its final form, a more indigenous design.
