Are you sure that TUSAS plans to build a twin engine supersonic flying wing, that seems like a very stupid Idea to me.
No supersonic flying wing has ever been built, and that's for a reason.
because of how close the control surfaces are to the center of lift At transonic speeds, the center of lift starts to move farther back with the shockwave and That's the problem. Now you’re trying to balance something using only inches rather than feet of leverage to work with.
it's like being on a see-saw and the pivot-point (fulcrum) moved closer to you… the effort becomes much harder.
