The U.S. Air Force received some 40,000 noise damage claims in the 1950s and 1960s from Americans regularly harassed by sonic booms from military jets.
“Engine installation is a critical part of achieving an overall low boom design,” said Coen, who is located at NASA’s Langley Research Center. “If we mount the engines in a conventional manner, we need to carefully tailor the shape of the wing to diffuse the shock waves. If we mount the engines above the wing, the shock wave can be directed upward and not affect the ground signature.”
