Investigation of Bird Strike criteria for Natural Laminar Flow wings (BirdStrike)
Date du début: 1 janv. 2013, Date de fin: 30 juin 2016 PROJET  TERMINÉ 

The BirdStrike project aims to establish a validated bird strike analysis capability, which enables the SFWA partners to simulate bird impact on a CFRP leading edge for a NLF wing. This will be achieved by setting up a combined program of test and analysis to determine the extent of damage and criteria to be applied to analyses of leading edge panels for NLF wings.The main scientific and technical work comprises six main research objectives in agreement to the present Call for Proposals (CfP) topic:1) Analysis of bird strikes on flat and representative curved panels at various angles of impact, using an existing bird impact model that will be provided by the SFWA Partners.2) Design and analysis of a supporting frame for bird-strike impact tests on flat and representative curved panels.3) Manufacturing of an agreed number of flat and representative curved panels that include supporting stringers, sparcaps or other structural features.4) Completion of impact tests at various angles.5) Validation of analyses and numerical models.6) Delivery of a tool that can predict the extent of damage in a representative Composite LE geometry.
