Typically when you’re flying an airplane,
you’re deflecting control surfaces in order to manoeuvre or to reject wind gusts. These deflecting surfaces make the airplane
more vulnerable to being detected by hostile forces We’re looking at modern flow control techniques,
which permit you, potentially, to be able to control the airplane in flight, without
the use of any kinds of mechanical surfaces. And we do that with a distributed array of
tiny little jets on the surface and trick the aerodynamics into believing that a flap’s
been deployed where in fact, it’s not been deployed.
