Dassault Chooses Thales Electric Starter-generator for Falcon 5X

Dassault has selected the Thales TopStart electric starter-generator system for the Falcon 5X. The equipment manufacturer claims the unit reduces weight and improves engine durability. The system marks the first time the Paris-based company has combined electric starting and power generation functions in a single unit for a business jet.

The new system is particularly well suited to the Falcon 5X’s new-generation engine, the Snecma Silvercrest, according to Guy Lefebvre, president of Thales Avionics Electric Systems. “The control laws provide for a harmonious start-up sequence,” he told AIN. The system exchanges data with the engine’s control unit and selects one start-up control law. It factors in outside air temperature and blade tip clearances, among other parameters, to ensure rotation speed and torque increase progressively.
