The Boeing Company has selected GE Aviation to provide the Electrical Load Management System (ELMS), the Backup Generator and the Backup Converter for the Boeing 777X aircraft.

“The advanced ELMS on the 777X will control 30% more power than the current system, while contained in the same size and weight,” said Brad Mottier, president of Business & General Aviation and Integrated Systems for GE Aviation.”

“The backup power generation system will provide twice the amount of power generation than the current 777 system,” added Mottier.  “This is our first commercial electrical power generating system, leveraging decades of experience on military applications.”

The advanced ELMS for the Boeing 777X will utilize the Boeing 777 ELMS design elements, to reduce aircraft maintenance time and cost, improving reliability and availability of aircraft power.  With the ELMS, backup generator and backup converter for the 777X, GE will utilize their Electric Power Integration Center in Cheltenham, UK and their Electrical Power Integrated Systems Center in Dayton, Ohio where they will employ state of the art dynamic software modeling, simulation and analysis to predict how the system and its individual components will perform, including full system testing within a copper-bird environment.

“By using these new state-of-the-art labs, GE will reduce development risk and mature these products before aircraft introduction to an extent never done before,” said Vic Bonneau, president of electrical power for GE Aviation.
