Hush kits developed by Stage III Technologies for Rolls-Royce Spey-powered Gulfstreams are back. Here at NBAA’08, the new owner of the design, Hush Kit Aviation, LLC, is exhibiting the first installation of an FAA-certified, Stage III hush kit on a Gulfstream II in the static park at Orlando Executive Airport.
Hush kits developed by Stage III Technologies for Rolls-Royce Spey-powered Gulfstreams are back with a new name and a new company. Yesterday at Van Nuys Airport in California, Hush Kit LLC, an affiliate of Hubbard Broadcasting of Minneapolis, flew the first production Stage III hush kit installed on a Gulfstream II (N20H), also owned by Hubbard, in preparation for the product’s debut at the NBAA Convention in Orlando, Fla., early next month.
Quiet Technology Aerospace has named Garrett Aviation Services as the preferred installation center for its Stage 3 hush-kit for Gulfstream IIs, IIBs and IIIs. Installations are also available from QTA’s own facilities in Miami and hush-kit development partner Business Jet Center in Tulsa, Okla. According to Garrett, the kit can be installed at its locations in Los Angeles and New York in less than 10 days at a price of $1.65 million.
The race is heating up in the Gulfstream hush kit market, as three providers maneuver for the inside track. Stage III Technologies and Quiet Technologies Aerospace (QTA) continue their respective and long-time efforts to obtain STCs for hush kits for the Gulfstream II and III.
Legislation to ban certain large transport aircraft that have hush kits from using all European airports starting next April has been scrapped by the European Union. Consequently, the U.S. withdrew a formal complaint submitted last year to the International Civil Aviation Organization. The U.S. maintained that the regulation, that applied to hush-kitted aircraft over 75,000 lb mtow, discriminated against U.S. manufacturers.
Miami-based Quiet Technologies said the FAA now has all the test data, and the company expects to receive an STC for its Gulfstream II/III Stage 3 hush kit this month, about two months later than the previously revised date of the long-delayed program. The $1.5 million system (installed) does not reduce takeoff or climb performance or adversely affect range at typical cruise speeds, according to officials.
Miami-based Quiet Technology Aerospace is nearing completion of about 45 hr of planned flight testing of its first FAA-conforming Stage 3 hush kit for Gulfstream IIs and IIIs. Flight testing of a GII equipped with the company’s translating-ejector type hush kit started in late May and follows 30 hr of baseline flight testing of the aircraft without the hush kit installed.
Making jet aircraft acceptably quiet can be a dirty job. Owners don’t want to spend the money, engine makers don’t want to compromise their products’ efficiencies and airport neighbors are rarely happy with the results.
