Airbus – E-Fan “Plus:” Launching a new era in electric flight

London, 28^th November 2017 – Airbus, Rolls-Royce, and Siemens have formed a partnership which aims at developing a near-term flight demonstrator which will be a significant step forward in hybrid-electric propulsion for commercial aircraft.

The three companies together announced the groundbreaking collaboration, bringing together some of the world’s foremost experts in electrical and propulsion technologies, at the Royal Aeronautical Society in London.

The E-Fan X hybrid-electric technology demonstrator is anticipated to fly in 2020 following a comprehensive ground test campaign, provisionally on a BAe 146 flying testbed, with one of the aircraft’s four gas turbine engines replaced by a two megawatt electric motor. Provisions will be made to replace a second gas turbine with an electric motor once system maturity has been proven.

“The E-Fan X is an important next step in our goal of making electric flight a reality in the foreseeable future. The lessons we learned from a long history of electric flight demonstrators, starting with the Cri-Cri, including the e-Genius, E-Star, and culminating most recently with the E-Fan 1.2, as well as the fruits of the E-Aircraft Systems House collaboration with Siemens, will pave the way to a hybrid single-aisle commercial aircraft that is safe, efficient, and cost-effective,” said Paul Eremenko, Airbus’ Chief Technology Officer. “We see hybrid-electric propulsion as a compelling technology for the future of aviation.”

The E-Fan X demonstrator will explore the challenges of high-power propulsion systems, such as thermal effects, electric thrust management, altitude and dynamic effects on electric systems and electromagnetic compatibility issues. The objective is to push and mature the technology, performance, safety and reliability enabling quick progress on the hybrid electric technology. The programme also aims at establishing the requirements for future certification of electrically powered aircraft while training a new generation of designers and engineers to bring hybrid-electric commercial aircraft one step closer to reality.

As part of the E-Fan X programme, Airbus, Rolls-Royce, and Siemens will each contribute with their extensive experience and know-how in their respective fields of expertise:

– Airbus will be responsible for overall integration as well as the control architecture of the hybrid-electric propulsion system and batteries, and its integration with flight controls.

– Rolls-Royce will be responsible for the turbo-shaft engine, two megawatt generator, and power electronics. Along with Airbus, Rolls-Royce will also work on the fan adaptation to the existing nacelle and the Siemens electric motor.

– Siemens will deliver the two megawatt electric motors and their power electronic control unit, as well as the inverter, DC/DC converter, and power distribution system. This comes on top of the E-Aircraft Systems House collaboration between Airbus and Siemens, launched in 2016, which aims at development and maturation of various electric propulsion system components and their terrestrial demonstraion across various power classes.

Egypt has signed an agreement with China to purchase J-10C fighter jets

Egypt has become the second country, after Pakistan, to order China’s Chengdu J-10C “Vigorous Dragon” fighter jets, marking a significant shift in its military strategy.

The announcement, made during the inaugural Egypt International Air Show from September 3 to 5 at El Alamein International Airport, reveals Egypt’s intent to replace its aging fleet of U.S. F-16s.

The J-10C, a highly capable 4.5-generation multi-role fighter jet, was showcased by China for the first time on African soil during the air show. It features advanced air-to-air and air-to-ground weaponry, making it a formidable alternative to Egypt’s current fleet.

Known for its air superiority missions, the J-10C has often been compared to the American F-16, which has been the backbone of the Egyptian Air Force since the 1980s.

However, with Egypt’s F-16s now considered outdated against modern air defense systems, the decision to transition to the Chinese fighters underscores a major upgrade in Egypt’s combat capabilities.

This move not only signals Egypt’s intent to reduce its reliance on U.S. defense systems but also reflects a broader shift in its international alliances.

Despite a long-standing defense relationship with the U.S., evidenced by a recent acquisition of C-130J Hercules transport aircraft through the U.S. Foreign Military Sales program, Egypt is clearly looking eastward.

The decision comes amid growing concerns over U.S. policies in the Middle East, including its stance on Israeli operations in Gaza, which may have influenced Cairo’s pivot to Chinese military technology.

China’s increasing presence in the Middle East and North Africa is bolstered by such deals, as Beijing continues to expand its influence through military cooperation and economic partnerships, particularly in energy imports.

The Egypt International Air Show provided a platform for showcasing this growing military-industrial relationship.
