The biggest issue wouldn't have been designing a power system that could bring a jet to mach speeds. The bragging rights for them were that the plane survived the transition to mach 1.
- craftyguy 9y agoDoes something magically happen at Mach 1.0 that would compromise structural integrity significantly more than, say, Mach .99...9?
- tim333 9y agoIt seems not quite - supersonic airflow would already be having an effect in places if the plane was doing 0.99 see https://www.quora.com/What-happens-if-an-airliner-reaches-Mach-1-sound-speed-1224km-h-or-768-mph# https://www.quora.com/What-happens-if-an-airliner-reaches-Ma...
- qwerty_asdf 9y agoIf you read the parts where they mention “buffeting” that’s the dangerous part, where uneven airflow introduces instability, causing the airframe to rattle. Buffeting occurs when the soundwaves of the noise of the craft and its motion directly affect the air as it flows across the surface of the plane. This happens as the plane enters the shockwave of the sound barrier, and ceases when they accelerate beyond the speed of sound. At and beyond Mach 1 the buffeting is behind the plane, and flight is smoother, with no rattling or shaking from the incidental turbulence. It also happens when decelerating, although it’s easier to decelerate safely through the buffeting quickly, since less time is spent in the shockwave, and a reduction in speed grants improved control.
- craftyguy 9y agoI see, thanks for the explanation
