Future of Aviation-Hybrid and Electric Aircraft
Ridwan, Roufun; Menyhárt, József; DE--Műszaki Kar
With few commercial aircraft in service, the electric aircraft industry is still developing. Creating dependable battery technology for extended flights and infrastructure for maintenance and charging present challenges. The thesis looks at how aviation might alter because of electric aircraft technology. In the rapidly growing aircraft sector, cryogenic superconducting propulsion for hybrid and all-electric aircraft is becoming more and more widespread. HEA is composed of mechanical and electrical parts, with additional energy coming from batteries and combustion-type power sources. With an emphasis on Urban Air Mobility applications and advancements in power electronics converters, electromagnetic design, thermal engines, and control techniques, the aircraft industry is investigating novel propulsion technologies for environmental reasons. Superconducting materials could increase the efficiency and compactness of aircraft electric propulsion in higher-specific-power electric motors. Aviation-compatible battery development is difficult to forecast, but with improvements in cell chemistry and pack design, 500 Wh/kg battery packs may be accessible in the mid-2030s. To develop long-range battery technology and evaluate the impact of electric aviation on local grids, industry, academia, and government must work together.
