Improving mechanical ice protection systems with topology optimization

In the context of more electrical aircraft, electromechanical de-icing systems provide a low-energy solution to protect aircraft’s surfaces from ice buildup. Such produce deformation protected surface leading stress production within and, ultimately, shedding thanks fracture. However, these may show limitations when it comes completely given surface. Ice delamination is often restricted part and remaining either requires energy be removed or just impossible remove. this paper, topology optimization substrate covered by thus investigated increase fracture propagation shedding. For that purpose, an problem, involving release rate but also mass stress, formulated. The numerical results how efficiency mechanical based protection can improved through modification substrate.
