This has the potential to significantly decrease the carbon footprint of air travel.
Wright Electric, on the other hand, is developing a fully electric plane that is specifically designed for short-haul flights. The company’s goal is to make electric flight a reality within the next decade, and it recently unveiled plans for a 186-seat electric plane that could cover distances of around 800 miles.
While these companies lead the charge, several other firms, including Airbus and Boeing, are also researching and developing electric and hybrid electric technologies for aircraft. Each company brings a unique perspective and set of skills to the table, which is accelerating the advancement of electric propulsion in aviation.
Public Perception and Acceptance of Electric Aircraft
Another critical aspect in the progress of electric aircraft propulsion is public perception and acceptance. Air travel safety is a paramount concern for passengers, and therefore, any new technology in the aviation industry must gain the trust of the public.
To date, electric aviation has had a good safety record. Electric motors are simpler and have fewer moving parts than traditional jet engines, reducing the risk of mechanical failure. And while battery safety is a concern, advances in energy storage technologies and rigorous safety testing should help alleviate these worries.
Moreover, electric planes promise a quieter, more peaceful flight experience, which could make air travel more appealing to passengers. A survey conducted by the University of Bath in the UK found that people are willing to fly less to reduce their carbon footprint. Electric aircraft, with their zero direct emissions, could provide an attractive alternative.
