| Abstract: | Aim to the pitch control problem of flying-wing configuration,a novel simple pitch control effector called a belly-flap is investigated to increase nose-up couple efficiently without unacceptable lift loss in this paper.Two-dimensional Reynolds-averaged Navier-Stokes calculations for various belly-flap configurations applied to an airfoil are described,and results are presented.The geometry parameters(size,location,deflection angle),ground effect and angle of attack are studied to detect their effects on th... |
