NEWS Airbus, Rolls-Royce, and Siemens team up for electric future Partnership launch E-Fan X hybrid-electric flight demonstrator 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. 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 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 www.ghmediabusiness.com 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 d WfVVBBGW&Fbf&W2VV7G&2&V677FVЦ6VG2BFV"FW'&W7G&FV7G&7&72f&W2vW 676W2rFRF6VvW2f"FF( 0fF6V7F"2FfRFv&G2V2bG&7'BvF&fV@Vf&VFW&f&6RFB0&RVff6VBBW72&VƖBf76gVV2FR'FW'2&R6֗GFVBFVWFrFRURFV66Vf&VFv2bFRWW&V6֗76( 0fƖvGF#Sf6f"fFࢇ&VGV7Fb4"'sRR&VGV7Fb'RB6R&VGV7F'cRRFW6R6B&R6WfV@vFFRFV6vW2W7FrFFFW&Vf&R&'W2&2&6R@6VV2&RfW7FrBf7W6p&W6V&6v&FffW&VBFV6w&V26VFrVV7G&f6FVV7G&0B'&BVV7G&2&V6&R6VVFF2rFR7B&֗6pFV6vW2f"FG&W76rFW6P6VvW2wwr&'W26УFRRf'&BVV7G&2FV6wFV7G&F"2F6FVBFfǐ##fvr6&VV6fPw&VBFW7B6v&f6ǒ$RCbfǖrFW7F&VBvFR`FR&7&gN( 2fW"v2GW&&RVvW0&W6VB'GvVvvGBVV7G&0F"&f62v&RFRF&W6R6V6Bv2GW&&RvFVV7G&2F"6R77FVGW&G2&VV&fVFRFV6wW&f&6R6fWGB&VƖ&ƗGV&ƖrV6&w&W70FR'&BVV7G&2FV6wFP&w&R62BW7F&Ɨ6pFR&WV&VVG2f"gWGW&R6W'Ff6FbVV7G&6ǒvW&VB&7&gBvPG&rWrvVW&FbFW6vW'0BVvVW'2F'&r'&BVV7G&06W&6&7&gBR7FW66W"F&VƗG
