Abstract

Based on a fully designed wing box section of a generic transport aircraft, two effects are investigated leading to surface waviness, namely process induced deformations (PID) and load induced deformations (LID). A DLR in-house waviness handling tool for the analysis and superposition of multiple waviness effects is introduced and applied. It is shown, that the results differ widely whether or not the effects are evaluated together. Finally, the remaining waviness is aerodynamically analysed using established methods.
