Preparing the future
Innovation is at the core of our strategy. We bring together customer needs and market trends and develop ambitious solutions allowing aircraft manufacturers to gain flexibility, reduce operating costs, and support sustainable development.
Safran Electrical & Power, the More Electric Aircraft revolution
Safran Electrical & Power is positioned in a breakthrough market with the conviction that in the medium term, everything that moves on a plane could be operated by an electric motor. The challenge is to migrate an increasing number of functions to electric and to replace hydraulic and pneumatic energy with electricity.
Therefore our Research and Technology programs are ambitious and are focused on new types of equipment, exploring new electrical solutions for the different phases of flight. The company pools its various resources and the full scope of its expertise to create new products that meet the needs of our customers.
Safran Electrical & Power combines distribution and wiring, which is unique in the market and promotes optimization of the energy chain on an aircraft.
Serge Bérenger, Vice President, Innovation and R&T.
Our coverage of the entire energy chain on board an airplane is unique. We design products at the forefront of technology and we have the ability to ensure their integration into aircraft systems by optimizing their overall weight, environmental footprint and configuration.
Safran Electrical & Power, the connectivity challenge
Building on our expertise in EWIS systems and beyond the distribution of power, Safran Electrical & Power also focuses on transport of data on board aircraft. Indeed, aircraft data management infrastructure is complex and changing, and our company explores technological opportunities to optimize it.
Our electrical harnesses carry aircraft systems' computer data. We are working on simplifying these exchange networks between different systems, taking into account issues of security, privacy and performance

Electrical Power Generation
NEXT GEN VFSG: starter-generators for commercial aircraft engines
In collaboration with the power electronics team in France, the Research & Technology team in the United Kingdom is in the demonstration phase of a variable frequency generator with choke function (starter). With 90kVA of power, this starter-generator is a generic support for various demonstration programs, adapting to different types of commercial aircraft engines. "What we're calling the Next Gen VFSG will couple the starter and generator function in order to allow air or electric starters traditionally used on engines and APUs to be removed, as well as optimization of the engine start phase. In one of its applications, it will contribute reconfiguring and moving the Accessory Gear Box to the ‘Core' engine" explains Yann Tondriaux-Gautier, R&T program manager at Safran Electrical & Power. "This optimization process will help to refine the nacelle and thus improve its aerodynamic performance. The technologies studied in the Next Gen VFSG aim for sensible weight reduction and increased performance of the VFSG and optimizations surrounding installation and its associated systems, all to reduce fuel consumption and improve the reliability and robustness of our systems." The demonstrator is in the design phase and the first unit is scheduled for the first quarter of 2016. "We will ensure that the starter-generator can quickly adapt to a power of 70 to 120kVA in order to cover more applications," Yann added.
Next Generation distribution
Safran Electrical & Power is working on the design and manufacturing of an electrical distribution cabinet that incorporates mountable power electronics (rack). So if one fails, just the damaged rack can be changed out instead of all of the equipment. "In line with our More Electric Aircraft strategy, we are also trying to design a cabinet that is easier to control, more compact, which includes the components (SSPCs, Circuit breakers, Contactors) that we manufacture in our factories and that is able to manage and better distribute power in a smaller product," explained Jérôme Mora, R&T Programs Director at Safran Electrical & Power.
ISS Power: optimize power electronics
With the ISS PWR project, the Safran Electrical & Power teams demonstrated their capabilities in designing the next generation of power electronics that allows aircraft manufacturers to carefully consider the development of the more electric aircraft. "Power electronics drive an aircraft's electrical equipment. Today, they require very heavy liquid cooling systems. ISS Power optimizes their performance, replacing the liquid cooling system with air, which significantly improves overall mass and reduces installation constraints," explained Jérôme Mora, R&T Programs Director at Safran Electrical & Power.
eCENTRIC, custom made for EWIS
The eCENTRIC project responds to increased electrical functions, sophistication of structures, composite appearance, and to the need to optimize the weight and reduce the energy consumption of the aircraft. "eCENTRIC is an equipped process that complements our existing business in defining EWIS, allowing us to cover its entire design cycle. We designed it and adapted it to our specific needs with our partner IGE-XAO, computer software developer and world leader in electrical CAD," explained Christophe Leguay, Process, Methods and Tools manager at Safran Electrical & Power. From the time the data is received from the customer until the delivery of a "Bill of Material" (BOM) that launches production, eCENTRIC is in charge of every stage and structures the design process for an aircraft's electrical interconnection system. It optimizes the electrical architecture of an aircraft to quickly incorporate the changes requested by the customer. It also improves cost monitoring and guarantees traceability. No data will be lost and those that are transmitted will have a universal format in order to interface with all existing design tools. It can therefore be used in any aircraft program.
Integration and certification
COPPER Bird®: a unique test rig for use in research into the more electric aircraft
Safran Electrical & Power has designed and constructed a means of electrical systems integration dedicated to R&T activities: COPPER Bird®. It is currently available to Clean Sky program partners for which it has been officially selected, following the previous European programs (POA, MOET, MEGEVE).
COPPER bird® serves to validate innovative architectures and equipment designed by aircraft manufacturers and major aeronautical equipment manufacturers in the context of collaborative research into the more electric aircraft. It also allows for product demonstrations of Safran's own developments on this strategic axis. For example, COPPER bird® tests and validates power electronics, high-speed electrical machines and associated functions such as electric starting solutions, on board energy management, operating or anti-icing. COPPER bird® provides Safran teams and manufacturers with extraordinary means that are adapted to the constraints and innovations related to the more electric aircraft. It also will continue its testing campaigns as part of Clean Sky 2, which is expected to begin activity in COPPER Bird® in 2016.
