Estimation of driving power: aerodynamic analysis, the load of the parts of aircraft (flap, slat, landing gear, brakes, control systems, loading devices etc.), kinematical parameters, power consumption. Selection of the rational source of power. Principal scheme of the driving, defining of the basic size of elements. Kinematical analysis: speed and acceleration. Selection of the materials for basic elements. Strength analysis and structural parametric optimizing. Drawing of the common view of the driving. Detail designing of some unit of the driving: structural analysis, defining of the dimensions, 3D simulation and strength-weight optimizing, examination of the 3D model functional ability, tolerances and the fits. Drawings of the details of the unit.
