Splet31. okt. 2024 · 3.2 Trailing Edge Flap Model. Trailing edge flaps are modeled based on grid deformation in FLOWer. For this purpose, the deformation module was extended. Two different kinds of flaps, rigid and elastic, can be realized within the code. For a rigid flap, the flap part of the airfoil is simply rotated around a defined hinge axis. SpletThe plain flap is hinged so that the trailing edge can be lowered. This increases wing camber and provides greater lift. A split flap is normally housed under the trailing edge of the wing. [Figure 1-63B] It is usually just a braced flat metal plate hinged at several places along its leading edge.
