This NASA video segment explores how scientists at NASA's Langley Research Center, Hampton, Va., design and test the Hyper-X aircraft. The Hyper-X is an experimental airplane designed to travel at Mach 10. Viewers learn that although engineers designed the Hyper-X with a slender body, a triangular-shaped tip was added to provide turbulent flow of air around the scramjet engine. Viewers also learn that engineers perform wind tunnel tests to measure an airplane's performance, evaluate the outcomes and make modifications if necessary. A demonstration of an extinguished candle illustrates the difference between laminar and turbulent air flow.
