Design of Fan Blades Subjected to Bird Impact [Conception des Aubes Fan Soumises a l'Impact Doiseaux]The quality of fan blades in terms of behavior is one of the major parameters affecting the safety of modern aircraft driven by engines with strong by-pass ratio. The reinforcements defined as necessary in certain areas of the profiles of the fan blades must be a compromise between the objectives of mechanical resistance and aerodynamic performance. SNECMA developed a methodology to forecast the impact behavior of the fan blades based on a mathematical model. In parallel, the progress made in aerodynamics made it possible to predict the consequences of these stresses related to ingestion on aerodynamic performance and still maintain high levels of performance.
