Quiet Technology Delivers 500th Inlet Cowl Upgrade
Carbon-fiber barrels for HTF7000- and PW300-series engines eliminate corrosion issues
Quiet Technology Aerospace
Quiet Technology Aerospace has delivered its 500th carbon graphite engine inlet cowl, which it said permanently solves corrosion issues on several business jet engine models.

Quiet Technology Aerospace (QTA) this week delivered its 500th inlet cowl upgrade incorporating a carbon-fiber replacement inner barrel to a U.S.-based business jet fleet operator. The milestone inlet will be installed on a Honeywell HTF7350 engine on a Bombardier Challenger 350, QTA told AIN.

The company’s inlet upgrade replaces the aluminum-based inner barrel with a lighter-weight carbon-graphite composite barrel that will not corrode. Barrel corrosion and acoustic-screen degradation are known issues with the aluminum barrels on HTF7000-series engines that power various super-midsize business jets. QTA also has a similar STC’d upgrade for Pratt & Whitney Canada PW300-series engines on the Hawker 1000, Learjet 60/60XR, and Dassault Falcon 2000EX/LX, as well as Rolls-Royce Tay Mk 611-8C turbofans on the Gulfstream G450.
