Kinematic and Dynamic Analysis of Primary FCS Circuits of Typical 25 Seater Transport Aircraft

Abstract

his research work presents kinematic and dynamic analysis of primary flight control surface actuation mechanisms including aileron, elevator and rudder of typical mechanically controlled transport aircraft. The 3D CAD models of the actuation mechanisms are constructed using SolidWorks. The circuit assemblies are exported to MSC ADAMS for detailed kinematic and force analysis. An elaborate simulation model is built in MSC ADAMS to understand the kinematic relations and to estimate the forces acting on all links, brackets and joints under the action of aerodynamic loads on the control surfaces. Analytical formulations are developed to verify the results of the force analysis. Further, the effect of inertia of control surfaces on the pilot forces is studied in detail and discussed
