Extended hybrid laminar flow control (xHLFC) has the potential to significantly increase the energy efficiency of transport aircraft by reducing their wing friction drag. This thesis investigates compliant, additively manufactured xHLFC suction panels for transport aircraft. While the previous chapters investigated the main components of the suction panel, such as the suction skin and the triply periodic minimal surface (TPMS) core structure, this chapter presents system-level investigations of the suction panel. Next to an additively manufactured suction panel that can be mounted to an xHLFC wing demonstrator and shows the printability of the suction panel, the system-level investigations include a fully stressed design analysis to determine the suction panel’s impact on the wing design, wind tunnel tests of a flat suction panel integrated into a flat plate, and the design of a suction panel matching a given pressure distribution and suction rate. The investigations show only minor mass penalty for compliant xHLFC suction panels manufactured from engineering plastics, successful transition delay with additively manufactured suction panels, and a suction panel design methodology that allows integrating passive suction rate control into the panel. The successful system-level tests presented in this chapter demonstrate the potential of additively manufactured suction panels as a new concept for an integrated design of suction panels, allowing various materials and complex surface curvatures.
