Falcon 5X first flight with Thales on board
Dassault’s Falcon 5X, the wide body twinjet, performed a 2-hour maiden flight from Bordeaux-Mérignac final assembly facility on 5 July, incorporating many inspiring innovations, including a Thales-built and optimized system for the generation and conversion of electrical power.
This is the first time Dassault Aviation has chosen a brushless starter-generator for one of its aircraft. The combination of electrical starting and power generation functions in a single unit leads to a better trade-off between weight, size and power than on any other aircraft in the same category. The extensive use of electrical power in this new business jet represents a significant step forward towards a more environmentally-friendly aircraft and will significantly reduce the total cost of ownership.
A world first in advanced electrical solutions
Each aircraft will be equipped with two starter-generators for the main engines, one starter-generator for the auxiliary power unit, three digital regulators, one electronic starter converter and three transformer rectifier units.
Thales is a major player in designing a wide range of electrical starter, generator and converter technologies currently in service on board various types of large-capacity transport aircraft, regional transport aircraft, business jets and helicopters.
This milestone paves the way towards the More Electrical Aircraft. The Falcon 5X performed the 2-hour flight with a preliminary version of the Safran Silvercrest® engines and will now embark on a short, preliminary flight-test campaign. The full-scale certification campaign will begin next year once Safran delivers certifiable engines for an entry into service of the airplane scheduled in 2020.
