You've got the gist of it. To be pedantically correct, the flaps are arranged so that the lift distribution and local pitching moments when they're deflected creates the same total-airplane pitching moment as the lift distribution and local moments that exist when they're not deflected. Therefore no trim change. That generally means that the flaps are close to the CG, but not necessarily directly on it.As for installing flaps on a tail-less delta or flying wing …. we have seen tilting centre trailing edge on Swift UL glider. We have also seen a few split flaps on late 1940s vintage experimental flying wings. They all seem to be close to the centre of gravity to minimize pitching.
Am I reading this concept correctly?
