Özet:

In this thesis, design and analysis of a hybrid trailing edge control surface is performed. Only camber motion and twisting motion of the trailing edge control surface are considered. There are four control surface configurations that are analyzed. For the first configuration, servo actuators actuating the control surface are inside the control surface volume and control surface is without pre-twist. For the second case, the control surface is pre-twisted and actuators are inside the control surface volume. For the third case, servo actuators actuating the control surface are inside the torque box volume and control surface is without pre-twist. For the final case, the control surface is pre-twist but actuators are inside the torque box volume. The proper servo actuator selections for all of the configurations are done by considering the available volumes of the control surface volume and torque box volume. The downward deflection limits of the trailing edge control are determined for all of the configurations. The advantages and disadvantages of all configurations are explained. The CAD model of the control surface is created by using CATIA V5- 6R2012 package software and finite element analyses are done by using ANSYS Workbench v14.0 package software.
