Testing Overview of the EADN Samples

Abstract

The several EADN leading edges were developed and assembled in the application scenario AS01 in the European SARISTU project. VZLU manufactured kinematic parts for wind tunnel model including auxiliary spar and assembled this test article. The functional test was performed for verification of the droop nose components. The second one, longer EADN was assembled for ground testing. All kinematic parts including auxiliary spar were also manufactured at VZLU. The functional test, static test of bending and cyclic test were performed on developed, manufactured and assembled test stand. All tests proved high-quality manufactured parts including the whole assembly and well-satisfied functionality of EADN. The third leading edge with manufactured kinematic parts was assembled for bird strike test. The bird strike tests of leading edge and two splitters were performed at VZLU too. This contribution is the description of assemblies of leading edges and overview of performed testing including results evaluation.
