Aero-TV: Quiet Technology Aerospace -- Turning Big Jets Into Good Neighbors

Noise Is A Huge Enemy Of Aviation Progress... The Quieter Our Birds, The More Welcome They Become

At the 2010 NBAA Convention, we took the time to get some peace and quiet... by visiting some folks that are breathing new life into elder bizjets. The FAA awarded Quiet Technology Aerospace a Supplemental Type Certificate back in January of 2003, that authorizes the installation QTA’s Stage 3 Hush Kit on all Spey-powered Gulfstream aircraft. The QTA Hush Kit is unique in its design, integrating the aircraft’s existing thrust reverser system with advanced noise suppression, without affecting aircraft handling or range.

The QTA Hush Kit uses a unique translating mechanism to enable integration of the acoustic system with the existing thrust reversers, requiring no additional controls. The ejector is mounted on two carriage assemblies, one on each side, and slides on low-friction linear bearings.

The ejector is mechanically linked to the Thrust Reverser System, such that when it is deployed, two "translating" links push the ejector aft and the thrust reversers’ doors deploy. Upon stowing the thrust reversers, the ejector is automatically pulled forward into the stow position.

Forward radiated fan noise is a contributor to both take off and approach noise levels. It is also the largest contributor to cabin noise. The high-pitched whine of the Spey engine is tamed by the QTA Hush Kit, which incorporates acoustic treatment to the Inlet Bullet to reduce the sound level of the fan. The QTA Hush Kit retains the original GulfstreamTM acoustically treated tailpipe, the original 5 lobe mixer nozzle is removed and replaced with a 12 lobe "fluted" mixer nozzle.

The 12 lobe nozzle works with the ejector in promoting the mixing of the ambient air stream with the jet exhaust. The major reduction in outside aircraft noise levels is achieved through this mixing.
