Abstract:
A dynamic model of a stabilized drogue with four control surfaces is developed to mitigate the aerodynamic disturbances caused by the bow wave effect and wind turbulence during the docking stage of hose-drogue systems. Numerical simulations are used to identify the aerodynamic characteristics of the drogue， and the data is simplified using linear and polynomial functions. The aerodynamic model is used to design a linear quadratic regulator （LQR） controller. MATLAB/Simulink is used to construct a hose-drogue model and verify the effectiveness of the actively controllable stabilized drogue in reducing the effect of disturbances. The study also investigates the effects of control surface deflection angles on hose catenary curves using a static model. Numerical simulations show that the actively controllable stabilized drogue reduces the effects of the bow wave and wind turbulence， which maintains the stability of the hose-drogue system and improves the success rate of aerial refueling.
