Abstract: We designed a complete coaxial rotor configuration helicopter with coaxial pusher type rotor. We made an aerodynamic analysis over complete model as well as rotor analysis. Based on the result of the old model, we modify the design of fuselage and rotor. Normally in helicopter, maneuvering is done by rotor motion and its effects. Some helicopter such as S-97 raider uses tail wing control surface. To study the combination of rotor effect and control surface deflection, we designed pusher coaxial rotor along with tail wing which has elevator and rudder surfaces. we found the Cp distribution along fuselage reference line due to deflection of rudder. Moreover, we compare performance modified model and the actual model.
