Imagine trying to figure out what physical designs and structural materials will best survive, fly and maneuver reliably under such conditions.

Katherine Banks, Vice Chancellor for Engineering and National Laboratories, The Texas A&M University System Keep in mind that this excruciatingly hot object is slicing through the atmosphere so quickly that it could fly from New York City to Washington, D.C. We’re talking about heat in excess of thousands of degrees.

Torrents of energy press scorching heat back against the object, changing how the object and the air interact. Watch out - those chemical changes radically alter the object’s aerodynamics and performance.Īt some point faster than Mach 5, a flying object heats the air so much that it literally bursts open air molecules. The definition of hypersonic speed is when an object moves so fast that it starts to change the basic chemistry of the air around it. That’s because the term “hypersonic speed” is not simply a cool way to say faster than Mach 5, five times the speed of sound or 3,850 miles-plus per hour. It becomes especially difficult if you are building a hypersonic flight system, something engineered to maneuver in flight so that it arrives at a precise destination, regardless of what obstacles might be in its path. For more than 70 years, aerospace engineers have demonstrated the knowhow to fly an object at hypersonic speeds.
