On the way to their target the rocket cradles broke up and released the darts at near hypersonic speed.

When the aircraft reaches hypersonic speed, it uses the heating energy from air friction to increase the heat capacity of the fuel (reform the fuel).

Some of the collapsing liner goes on to form a constantly stretching jet of material travelling at hypersonic speed.

During descent, the orbiter passed through different layers of the atmosphere and decelerated from hypersonic speed primarily by aerobraking.

Most of the jet travels at hypersonic speed.

It would be a single-use hypersonic vehicle.

Designs using compression lift, waveriders, remain an interesting possibility for hypersonic vehicle designs, although only testbed models have been flown.

Firstly, plasma could be much easier generated for hypersonic vehicle at high attitude with quite low atmospheric pressure and high surface temperature.

His doctoral thesis developed a new approach for robust intelligent flight control of hypersonic vehicles.

Because of these problems, waveriders have not found favor with practical aerodynamic designers, despite the fact that they might make long-distance hypersonic vehicles efficient enough to carry air freight.
