Enhanced Adaptive Droop Nose—from Computer Model to Multi-functional Integrated Part

Abstract

The INVENT GmbH rises in the EU project SARISTU under the lead of Airbus and in cooperation with project partners to the challenge to manufacture a composite gapless and flexible droop nose (enhanced adaptive droop nose, EADN) on the basis of computer models and in compliance with standards and requirements of industrial integration. Therefore, various individual disciplines are integrated into one single manufacturing process and, thus, into one multi-functional part. This is an iterative process which develops along the entire range of structural engineering from material and substructure specimen and tests to the design of tooling and processes. Regarding the industrial integration of the morphing wing leading edge, the individual technical disciplines such as protection against erosion, lighting strike and bird strike as well as deicing were selected for SARISTU. Based on the overall design activities of the DLR, INVENT integrates the surface protection of Airbus Group Innovations, deicing of GKN and lightning strike protection into a flexible composite structure.
