I might have. Steve is an Aerospace Research Engineer in the High Speed Research Branch. He's worked on things like the oblique wing. We live near Detroit where a terrible crash happened because of this issue. I remember that accident.
Slats are a very important part of a jet liner.
My work mostly involves trying to measure the noise of these devices so that the airplane is quieter when it is landing. Modern jet liners use both leading edge slats and trailing edge flaps to increase the lift of the wing. This is one of the configurations we are testing in the 7 by 10 wind tunnel. Supersonic, of course, means it travels faster than the speed of sound which is about 700 miles per hour. When we do acoustic test we don't want any reflections from the wind tunnel walls.
