Without the intervention of new policies\, global aircra ft emissions are projected to triple by 2050. Ambitious goals have been se t by the aerospace industry for the next three generations of commercial t ransport aircraft to ensure sustainability of the industry. This includes a better than 70% reduction in aircraft fuel burn\, along with significant reduction in noise and other emissions. These challenging goals require t he development of disruptive technologies beyond the current trends in the aviation industry.\n\nOne approach being explored to meet these targets i s the use of electric/hybrid-electric propulsion. Studies show that commer cial transport aircraft with a 'turboelectric distributed propulsion syste m' is able to reduce the mission fuel burn by 70-72% on an intercontinenta l mission without compromising payload\, range or cruise speed. This is ac complished by using an electric propulsion system that decouples the power producing parts of the system from the thrust producing parts. Fifteen el ectric motor driven turbofans were mounted on a continuous nacelle and two large turbo-generators located at the wing tips were employed. Small elec tric aircraft are already being produced and offered commercially\, but si gnificant challenges prevent scaling up of the technology to commercial av iation. Megawatt scale electrical machines and drives with specific power better than 6 kW/kg will be required to make these systems viable.\n\nThis talk will describe the application space and key enabling technologies be ing explored.\n\nSpeaker(s): Kiruba Haran\, \, Kiruba Haran\, \n\nAgenda: \n6:30 – 6:45 PM: Sign-in and Meet & Greet (Refreshments provided)\n\n6: 45 – 7:45 PM: Seminar – Tech Talk by Prof. Haran\n\n7:45 – 8:15 PM: Q&A\n\n8:15 – 8:30 PM: Wrap-up and Meeting End\n\nRoom: 4070\, Bldg: Ele ctrical and Computer Engineering Building (ECEB)\, 306 N Wright St\, Urban a\, Illinois\, United States\, 61801 LOCATION:Room: 4070\, Bldg: Electrical and Computer Engineering Building (E CEB)\, 306 N Wright St\, Urbana\, Illinois\, United States\, 61801 ORGANIZER:tim.oconnell@ieee.org SEQUENCE:2 SUMMARY:High-Specific-Power Machines and Drives for Aircraft Propulsion URL;VALUE=URI:https://events.vtools.ieee.org/m/41630 X-ALT-DESC:Description: <br /><p>The global aviation industry emitted 781 m illion tons of CO<sub>2</sub>&nbsp\;in 2015\, a number which is expected t o grow as air travel grows rapidly in emerging markets. &nbsp\;Without the intervention of new policies\, global aircraft emissions are projected to triple by 2050.
