Abstract
Methods of forming a curvature into a composite stiffener and a forming tool are presented. The composite stiffener is positioned in a forming region created by a base assembly and an upper assembly. A first airflow is applied through the material of the base assembly. A second airflow is applied through the material of the upper assembly. A plurality of brackets of the upper assembly is moved relative to each other to change a curvature of the forming region along a length of the forming region to form the curvature into the composite stiffener.
