Description of the job
Are you looking for an internship? Would you like to discover the work in the development environnement? Then apply now! We look forward to you joining us as an intern (m/f) at Airbus Helicopters (35 hours/week, flexi-time).
Start: Spring / Summer 2018
Duration: 6 months
Helicopter vibrations significantly affect component structural integrity and life, instrumentation and operator comfort and control. Finite Element Modelling is one of the favorable approach that allows a physical understanding and modeling of dynamic properties such as eigenfrequencies and mode shapes. Interior acoustics is a key contributor to passenger comfort in helicopter cabins. Being able to analyse noise sources contributions and to model them is required to optimize sound-proofing treatments with limited impacts on integration, weights and costs.
