Abstract

The paper deals with estimation procedure of Lift-to-Drag ratio losses due to longitudinal trimming for several Joined Wing configuration in wide range of lift coefficient. A software for automated calculation of aerodynamic characteristics has been developed, that permit to explore an influence of elevator parameters (elevator span, position and wing configuration) on trimming characteristics of aircraft. The results of calculation for different layouts of Joined Wing are presented, by which it can be concluded that in some combination of the elevator parameters Lift-to-Drag ratio losses take negative values, hence, overall aerodynamic performance of trimmed configuration are better than for wing with zero elevator deflection. The usage of a developed software and proposed methodology make possible rapid evaluation of control surface parameters in wide range of parameters at early design stage.
