Engineering method integrated with CAD-system for optimizing the horizontal empennage parameters of the maneuverable aircraft

This work describes the design of the horizontal empennage of a maneuverable aircraft in a unified environment combined with CAD/CAE-systems. The development of a digital model of the horizontal empennage ensures the compliance with all specified criteria. We can estimate the efficiency of the empennage using the value of moment produced by the horizontal empennage which the empennage can create with respect to the corresponding axis of the aircraft. In the study we test several optimization methods of for supersonic aircraft and develop a new optimization method, which enables us to obtain the optimal geometrical characteristics of the horizontal empennage in the automatic mode in the created automated adaptive parametric system in the application "Modelling" CAD-system NX 7.5. The adaptive parametric system is a parameterized model of the kinematic control scheme over the horizontal aircraft empennage in several positions.
