Abstract

Most of the aeronautic skin parts are made through stretch forming of aluminium or titanium sheet metals over rigid fixed dies. In the aerospace industry, the stretch forming of aluminium or titanium sheets is widely used to produce aircraft skin, such as blended wing body sections, fuselage sections and nacelle skins. As the demand for more efficient and economical commercial transport increases, the requirements for reduced weight and improved performance become greater. In this work explicit FEM simulations have been used to analyze the forming process of an aeronautical engine fairing in order to numerically compare: tangential stretch forming, extensively used in the aerospace industry and single action drawing processes effects on the studied component. Titanium alloys have their advantages and disadvantages, and two important tasks are the understanding of the behaviour of the alloys and the matching among particular alloys and processes in order to maximize structural and operational efficiency. Equally important it is the ability to develop a fabrication practice that does not severely degrade material properties and that can be implemented at reasonable cost.
