An Iterative Method for Estimating Airfoil Deformation due to Solid Particle Erosion
Journal Title: INCAS BULLETIN - Year 2014, Vol 6, Issue 1
Abstract
Helicopter blades are currently constructed with composite materials enveloping honeycomb cores with only the leading and trailing edges made 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 methods for turbo-machineries.

IAR-93 military aircraft monument
In this presentation, we will concentrate on the vertical support, which is free from all sides. A Finite Element Model (FEM) of the IAR-93 aircraft monument has been developed in PATRAN/NASTRAN®, partly from a previous...
Dynamic study of the virtual prototype of the IAR-99 SOIM Aircraft
This paper contains a dynamic study of the IAR-99 SOIM aircraft using ADAMS, multibody dynamic solutions. First, the analysis of the whole airplane is envisaged and then the analysis of the flight control system and the...
