Custom Manufacturing of a Hushkit System for the Aerospace Industry

MP Aero, a leader in manufacturing and repair of aircraft components, was approached by a client to custom manufacture a hushkit system that would be used for noise suppression on a Gulfstream jet engine.  This hushkit was composed of an alternating lobe exhaust nozzle, a fuselage-mounted acoustically-lined ejector, and a cascade style thrust lever. Following the customer-supplied design/build to print orders, the parts went straight into production.  Made from a titanium honeycomb core, nickel-chromium based superalloys, titanium forgings, and an aluminum cowling, we fabricated the parts using capabilities such as super plastic forming, stretch forming, hot sizing, 5-axis machining, composite bonding, and electron beam welding.  The parts were finished with an anodized or titanium anodized coating, chemfilm, dry film lubricants, primer, and paint.

This hushkit system reduced reverse thrust noise in the cabin and outside the plane; reduced temperatures, stresses, and vibration loads on the engine; and reduced empennage vibrations and associated fatigue-inducing stresses.
