Safran is to develop the field of hybrid propulsion

Safran in order to reduce the carbon footprint of air transport has been unremitting efforts: group has long been committed to lighten equipment weight, and improve the energy performance of engine.A promising technology in recent years, the development momentum is increasingly strong: hybrid propulsion.Vincent Garnier concluded:"Transport using hybrid is combine two kinds of power source, to ensure that transport propulsion power.And specific to the peak, is for a certain percentage of the propeller is introduced into electricity, or to improve the current engine, or to develop a true hybrid propulsion system, completely break the architecture we know it today."

Control of high power

To cope with the challenge of these technologies, the group needs to develop multiple areas, and to develop skills in specific areas, such asHigh voltageandHigh power control.Vincent Garnier says:"This is not strictly related to new areas, but considering the challenges inherent in hybrid, we need to conduct profound shift."Therefore, the design of the electrical system will need to in the futureElectrical, mechanical and thermal skills, as well asElectromechanical integration skills.Wiring areasAlso need to adjust according to the new material, conductive and insulation materials, lighter and stronger.Power electronics is the key to ensure the quality of the power signal, it will explore architecture and integration components in the power of the new frontier.

In addition, all related to system function need to be extended, to support the development of the hybrid: design innovation chain of hybrid electric system architecture, system engineering has been to the smallest components of operation optimization, management of thermal system and the interaction between power system energy system architecture...And, of course, the field of electromagnetic compatibility, the group already exists within the technology, its importance will be further strengthened.

Many put forward by the internal and external demand

Where can I get these skills?Vincent said Garnier:"Some of the skills already exists within the group and we willThrough training to further development,

This kind ofTalent competitionWill affect the group's companies: it's in the study of high power electrical system of the company (the peak electrical and power supply company, safran electronics and defense), and of course the design propeller or embedded electrical system of the company (safran aircraft engine company, safran helicopter engine company, the peak power plant).Since the outbreak, the industry network seminar organized by the ministry of group is also helping to promote the company's internal recruitment requirements, and promote the group's internal flow.

About the choice of the future

Hybrid is our future!According to Vincent Garnier estimates:"from2025Beginning in, small power hybrid propulsion system (tens to hundreds of kw) will be sent to you by commuting tools or new applications such as urban transportation vehicleFirst appearance in the market.(mw) and high power hybrid propulsion system will be in later,May be2025-2030Years, appeared in the regional flight device.Hybrid thermal devices, meanwhile, will promote the emergence of electric propulsion system, further reducing energy consumption, and increase flexibility."

Safran said, head of the science and technology research and development center, there is no doubt that group in the field of hybrid promising."Electrical technology has a place in the group, because of its application in the field of propulsion, electrical technology and materials and machinery,Be the peak real core areas.In this area is a wise decision, also can ensure the update progress on this field, because we're in the history of the opening, everything needs to be started!"
