Boeing/USAF X-51 WaveRider

Posted December 07, 2013 4:52 PM

From Popular Science:

On May 1, this 25-foot, 4,000-pound test bed for future missiles survived the longest air-breathing hypersonic flight: three minutes at Mach 5. It's the first true flight of a scramjet, a type of vehicle in which supersonic force pulls, burns, and accelerates oxygen without any moving parts (at these speeds, they'd melt).

'...without any moving parts (at these speeds, they'd melt)....'

.

This seems to imply that moving parts melt at lower temperatures (speeds?) than non-moving parts.

didnt NASA test a hypersonic scramjet that went Mach 9.9?

and how do start these things? with a booster rocket, or dropped from a B-52?

Pretty poor sentence structure there... Oxygen doesn't burn, according to my understanding.

There may be no moving parts in the intake, combustion, and exhaust chambers, but I suspect there is a fuel pump somewhere...

...awfully few details for something that happened half a year ago.
