Up to now the best results have been obtained with PSP in transonic speed ranges because of the high absolute pressure differences. The main challenge to get acceptable PSP results on one hand is the ...

NASA's Sustainable Flight Demonstrator (SFD) project recently concluded wind tunnel tests of its X-66 semi-span model in ...

An aircraft flies transonic when it reaches the range of speeds just below supersonic, which is Mach 1. Flight 11’s primary objective was to expand dynamic pressure to 383 KEAS (knots equivalent ...

As Boom explains in a press release, transonic speed is just shy of Mach 1. It is so close, in fact, that XB-1 experienced "the highest dynamic pressure the aircraft will ever experience." The XB-1 is ...
