CO2 Lasers Expose Hypersonic Flow

Paula M. Powell

A two-hour flight from New York to Tokyo could someday be a reality with the development of a hypersonic transatmospheric vehicle. Such aircraft, though, would routinely face aerodynamic drag and heating on a par with conventional spacecraft developed for less-routine flights. In the early 1990s, researchers first coined the term DEAS, or directed energy air spike, to describe a method to reduce drag and heating by adding energy to the air ahead of the vehicle. One way to accomplish this would be to focus a powerful laser beam ahead of the flight path. Marco A.S. Minucci and colleagues at...Read full article
