A tailless aircraft suffers from low stability because its momentum arm is short. Therefore, the margin of the position of the center of gravity is limited. As a way of improving the stability, Plank wing, washout and swept wing are usually adopted, which is not suitable for the tailless aircraft of light body and low drag coefficient. In this paper, simulations are conducted to realize high stability of this aircraft by moving the center of gravity, and found out that the longitudinal stability is improved by this technique.
