As the global leader in the landing gear and brake system, safran landing gear systems for the future of narrow body and wide commercial aircraft developed groundbreaking electric front wheel steering and closed system.

Front wheel steering and actuator current release by aircraft hydraulic system of the development of power network.With the aircraft's electrical system connection, safran landing gear system of the company's new electric hydrostatic actuator (hereinafter referred to as the "EHA") will use the front of the plane electric pump of hydraulic power as the driving source.

The new system for aircraft manufacturers and airlines brings many advantages.First of all, its retained the unparalleled hydraulic power, at the same time help the plane electrification, and optimize the power consumption.The system also simplifies the aircraft structure, and reduce weight.In addition, it is a "plug and play" system, easy to install and maintain.Safran landing gear systems, modular EHA system can also adapt to aircraft manufacturers differentiation in the architecture and system interface requirements.

The latest innovation was with safran electronics and defense companies and the peak electrical and cooperative development of power supply company, the former provides EHA control electronic equipment, which provides the power electronic devices and wiring harness.

To accept the system of landing gear system test at the peak of the firm's new trial on the stage, the development of the test bed based on DELTA electric nose gear demonstration project.It is worth mentioning that in combination with the company used on the platform of collaborative robot and data processing integration wheel well and simulated flight conditions (such as doors and aerodynamic load together with extreme temperature) on the landing gear on and function was tested.

Safran landing gear system executive vice President of corporate strategy development Walid Hamzeh said:"Before us is a great pleasure to launch its first electric landing gear system, this will make our customers reduce the operating and maintenance costs.The product will be added to our plane electrification system option, of course, also including our continuous improvement of electric glide solutions.This two systems clearly reflect the low carbon of safran commitment and continuous research and development process, in order to support the realization of the commercial aviation carbon neutral by 2050.This brings us a step closer to the future plane."

Safran company is developing "electric taxi" landing gear system (e - taxi) system will greatly reduce the aircraft ground mobile emissions 61% to reduce carbon dioxide emissions, nitrogen oxide emissions by 51% -- at the same time also will fly every time the fuel consumption by 4%.
