Hypersonic vehicles require control mechanisms other than traditional flaps and fins.
ICBMs travel faster than current hypersonic vehicles.
The shape of the rocket nozzle plays a crucial role in hypersonic flight.
Air temperature and pressure affect hypersonic flight performance.
The U-Haul model surprisingly withstands hypersonic airflow.
Why do hypersonic vehicles need control mechanisms other than flaps and fins?
—At high altitudes, there is not sufficient drag or aero force for traditional control surfaces to work effectively.
How fast do ICBMs travel?
—ICBMs can reach speeds of up to 7.8 km/s.
What determines the Mach number in hypersonic flight?
—The Mach number is fixed by the geometry of the nozzle in the hypersonic wind tunnel.
Why is air heated in the wind tunnel?
—Heating the air prevents freezing and condensation during the hypersonic airflow test.
Can a U-Haul truck withstand hypersonic airflow?
—Surprisingly, the U-Haul model successfully withstands hypersonic airflow in the wind tunnel test.
