Quiet Technology Aerospace (QTA) has delivered its 200th inlet cowl upgrade featuring a carbon-fiber replacement inner barrel. The milestone composite barrel was installed on Albertsons’ Gulfstream G280.
According to QTA, the work involves replacing the jet engine's original aluminum-based inner barrel with a lighter-weight carbon composite barrel that fixes the root cause of the corrosion issue and comes with a lifetime warranty. Besides the G200/G280, QTA holds STCs for composite barrel retrofits on the Bombardier Challenger 300/350 and Learjet 60; Dassault Falcon 2000LX/EX; Embraer Legacy 450/500 and Praetor 500/600; and Hawker 1000.
QTA is also making progress on a similar solution for its eighth airframe candidate: the Gulfstream G450. The company said it is now in the final stages of assembling the first G450 article for FAA conformity to finalize the STC. “This particular inlet offers substantial weight savings of 40 pounds…and will eliminate corrosion permanently on the G450,” it said. QTA expects to have the G450 STC in hand by the end of this month, with exchange inlets available next month.
