Does a delta-wing aircraft take off with elevons down?

Question

How does it take off?

Answer 1

It moves the elevons up. just like a regular airplane.

Delta-winged aircraft are identical to conventional aircraft in that they have more surface area behind the centre of gravity than in front of it. This gives the elevons a lot of authority to rotate the nose up.

While this seem like creating negative lift (and it is) it is only on the aft part of the wing. The forward part of the wing starts to generate lift when it is at a high angle of attack.

The forward part of the wing is essentially a low aspect wing that creates vortexes from the high pressure air spilling up over the leading edge. It uses these low-pressure vortices to create lift at much higher angles of attack than are possible with conventional wings.

Delta winged aircraft are generally unstallable. The Concode is an excellent example.

Answer 2

Delta-wing aircraft are still airplanes. They still follow the same rules as all other airplanes do. Elevator (or elevons) go up, tail goes down. Its the same rule that a C-152 follows
