The optimization platform developed by ESTECO assisted the Italian leader of complex aeronautical systems in enhancing aerodynamic performance by 2.5%, while reducing wing weight by 4%


Trieste (Italy), 12th March 2013 - Alenia Aermacchi, the Italian leader in complex aeronautical systems for commercial and defense aircraft, leveraged modeFRONTIER software in wing design optimization. The platform, developed by ESTECO, turned essential in enhancing aerodynamic performance by 2.5% while reducing wing weight in new generation planes.

In an ambitious collaborative venture, Alenia Aermacchi is heading the Green Regional Aircraft (GRA) design team of the The Clean Sky Joint Technology Initiative, committed to developing environmentally friendly aircraft. Domestic air travel of the future will meet demands for: weight reduction, aerodynamic efficiency, high level operative performance, compliance with emission standards, and respect of noise limits.

Alenia Aermacchi choose modeFRONTIER multiobjective platform to reach ambitious goals like lowering aircraft drag, wing weight, and environmental impact of lower speed conditions, while enhancing the overall environmental performance measured by fuel consumption and noise generation. Seeking the most promising solution for this new generation aircraft, the studies performed with modeFRONTIER involved the optimization of two wing shapes: one to analyze aerodynamic performance, and another to pursue weight reduction of the wing.

modeFRONTIER helped achieving remarkable enhancement for both wing configurations, while still complying with Top Level Aircraft Requirements (TLAR). “modeFRONTIER has proved to help effectively the design team in identifying feasible solutions and achieving a 2.5% enhancement of aerodynamic performance and a 4% wing weight reduction”, says Enrica Marentino, CFD Specialist at Alenia Aermacchi.
