Dassault Aviation’s long-awaited unveiling of the Falcon 5X large-cabin, long-range business jet is being accompanied by a number of Falcon 5X supplier announcements.

French engine manufacturer Snecma (Booth No. N5506) revealed details of the flight-test program for its new 11,450-pound thrust Silvercrest engine for the Falcon 5X. The program’s next major milestone calls for Snecma to fly its Gulfstream GII testbed fitted with the engine from Texas to obtain an experimental certification for the Silvercrest, planned by the end of the year. It will then fly the aircraft to Istres in southern France to complete the engine flight-test program.

Thales (Booth No. N216) is displaying its “TopStart” electrical starter-generator and power conversion system, designed to start the Silvercrest turbofan and generate main electrical power. This is the first time that Dassault has chosen a brushless starter-generator for one of its aircraft, Thales said.

The TopStart shipset consists of two AC starter-generators for the main engines, one smaller AC starter-generator for the auxiliary power unit, three electronic regulators, one electronic starter converter and three transformer rectifier units.

Guy Lefebvre, Thales Avionics Electrical Systems president, said the system has been integrated on Snecma’s Gulfstream GII flying testbed.

Liebherr-Aerospace (Booth No. C11407) is supplying the air-management system, including air-conditioning and cabin pressure control systems, and Silvercrest engine bleed-air system, which includes high-pressure and high-temperature valves, a pre-cooler, high-pressure ducting and related sensors and controls.

PPG Aerospace (Booth No. N3926) is supplying uniquely shaped, lightweight glass windshields and side cockpit windows “that accentuate the cockpit’s aerodynamics and afford expansive visibility,” the company said. The windshields and windows are designed with three plies of Herculite II chemically strengthened glass.

The transparency group of Nordam (Booth No. N2521) in Tulsa, Okla., will provide cabin windows for the Falcon 5X.

A unique aspect of the 5X is its “zenith window,” business aviation’s first skylight, according to Vision Systems (Booth No. C9522), which is providing the skylight’s SPD-SmartGlass variable light transmission window. The window’s SPD-SmartGlass technology was developed by Research Frontiers.

BE/Aerospace was chosen for several 5X products, including seating and a divan, plus cabin lighting and the vacuum waste system. The lighting is a full-spectrum wash light using LED technology with passenger control of color.
