Nacelle Systems

A nacelle system is the aerodynamic structure that surrounds a jet engine. 

It includes the structure commonly referred to as engine cowling, and also encompasses other components such as the inlet cowl, fan cowl, thrust reverser, core cowl and exhaust system.

As the world’s leading supplier of nacelle systems, Aerostructures constantly invests in critical research and development activities, such as advanced design, new material systems and manufacturing processes.  These lightweight technologies are capable of making aircraft more environmentally friendly through increased fuel efficiency and significantly reduced engine noise.​
