2,180 km/h x 10 = 21,800 km/h = 6 km/s
Article claims 25600 km/h = 7 km/s
(You need 7,9 km/s to go into space)
Slightly not enough to fly into space. Once again, why do we need it?
- skykooler 10y agoMore accurately, you need 7.9 km/s to get into orbit. You can fly into space at a far lower speed of about 1.2 km/s; you just will fall back. That said; travelling at 7 km/s at 12 km seems ludicrous; air is over 100 times denser at that altitude than at 25 km, where the Space Shuttle reentered the atmosphere (at about the same velocity). So this aircraft would need two orders of magnitude better heat protection than the Space Shuttle. Not to mention the aerodynamic drag at these altitudes and velocities, which will be tremendous.
- out_of_protocol 10y agoExactly. ... And this is that article claims, right?
- skykooler 10y agoThe article claims an aircraft design. To meet such a design would require no less than a revolution in materials science.
