Description
Summary:The purpose of this paper is to study the roll control of the flapless aircraft under low-speed and high-speed flight states and investigate the equivalent control effect (ECE) and the power consumption of the pneumatic control. First, the roll moment coefficient of the aircraft with different aileron deflection angles is calculated. Then the intensity of the jet is adjusted to match the roll moment coefficient, so that the deflection angle of the ailerons and the intensity of the jet corresponding to the same rolling moment are found. Based on the realization of the roll control, the aerodynamic efficiency of the flapless aircraft is evaluated by using the equivalent lift-to-drag ratio (Ecc) considering power consumption. The ECE curves of the pneumatic roll control under low-speed and high-speed flight states are obtained. Under low-speed flight state, the increment of aerodynamic efficiency brought by the jet cannot make up for its power consumption. Under high-speed flight state, the aerodynamic efficiency increment brought by the pneumatic control can compensate its power consumption before Cl = 0.061.
