Complete nacelle system design

We have the capability to design and manufacture the full aerodynamic structure that surrounds a jet engine.

Our nacelle system integration expertise goes into designing optimized solutions for every component of the nacelle from inlet cowl, fan cowl and thrust reverser, to engine exhaust. We don’t just stop at the structure – our expertise includes the design and integration of mechanical systems like the ice protection system, door opening system and thrust reverser actuation. We are also the engine buildup provider of choice for programs from today’s leading engine manufacturers.

As technology continues to evolve, we invest a significant amount of research and development funds into developing new technologies. These technologies are focused on making planes go further while reducing fuel burn, emissions and noise for a more sustainable future.

Hover over the nacelle components shown below to see examples of how our next-generation nacelle technologies are redefining aerospace.

Thrust reverser

Hidden link reverser

Patented designs improve performance with removal of drag links and lower bifurcation.

Translating sleeve

Thermoplastic or epoxy

Low drag liners enables significant reduction in fuel burn.

Exhaust system

Titanium, Inconel, or Ceramic Matrix Composites

Patented advanced acoustic treatment solutions.

Inner fixed structure

Titanium LID or Composite

Proprietary titanium LIDBond™ enables elimination of thermal protection and improved durability.

Fan cowl

"Hollow hat" thermoplastic or epoxy

No honeycomb core for damage tolerance and ease of repair.


Patented aluminum deep-draw lipskin

Enables natural laminar flow with no split lines. Pneumatic or electric de-ice systems.

Inlet acoustics

Short inlet acoustic inner barrel

Novel multi-degree of freedom liners enabling required attenuation over smaller area.


Our advanced acoustic technologies don't just support the stringent noise reduction requirements for next-generation aircraft, but also reduce fuel burn.

Our APT (Advanced Perforate Technology) is just one of the many technology implementations that we are applying to improve aircraft sustainability. With APT, we can produce repeatable, small hole perforations, which reduces aerodynamic drag and improves noise attenuation for nacelle inlets and thrust reversers.
