Supersonic tunnels generate winds faster than the speed of sound (768mph or 1,235.9 kph). Hypersonic tunnels create scary-fast wind blasts of 3,800mph to 11,400mph (6,115.5 kph to 18,346.5 kph) -- or even faster. Read More Wicked Wind Tunnels General Motors owns the world's bigge...
Fishlegs: "He's too fast, Hiccup!" Hiccup: "Not for a Night Fury!" ” — The duo referring to a Speed Stinger The Night Fury is among the fastest known dragons. It is said to be the only dragon known to reach speeds that break the sound barrier. The Night Fury's streamlined ...
”, McCullough revealed that he had been present at a secret North American location for the first flight of the Phase Two EcoJet. The technology, he said, is maturing fast but his assertion that it was creating a toolkit for developing a future aircraft was easily missed. Many...
SpaceShipOne sped from transonic to supersonic velocity, running its rocket motor for 15 seconds, and ascending to just above 62 miles (100 kilometers) over Earth. It therefore cleared the Kármán line, a widely recognized definition of the boundary of outer space. "I figured if we had bad...

Even then, this is simplified because the slip line will not be straight and the Venturi effect does not actually hold for supersonic flows anyway, as the relationship between area change and flow rate changes completely. Second, trying to explain an aerospike engine on a page aimed ...
