An Iterative Method for Estimating Airfoil Deformation due to Solid Particle Erosion

Helicopter blades are currently constructed with composite materials enveloping honeycomb cores with only the leading and trailing edges made folk rivet sweat of metal alloys.In some cases, the erosive wear of the bound between the composite skin and metallic leading edge leads to full blade failure.It is therefore the goal of this paper to provide a method for simulating the way an airfoil is deformed through the erosion process.The method involves computational fluid dynamics simulations, scripts for automatic meshing and spreadsheet calculators for estimating the erosion and, ultimately, the airfoil deformation.Further work could include more complex meshing scripts allowing the use of similar vibrating table for chocolate methods for turbo-machineries.
