Why we write about this topic:<\/summary>

Flying is harmful to the environment because of high CO2\u00a0<\/sub>emissions. It is therefore important to design and manufacture cleaner aircraft, which these students have done successfully by making a fully electric plane. <\/p><\/div><\/details>\n\n\n\n

A student team at ETH Zurich has successfully constructed a four-seater electric aircraft with a modular battery called e-Sling. The vehicle has now taken flight for the first time, says the university in a press release<\/a>.<\/p>\n\n\n\n

For two years, a team of around twenty ETH students worked tirelessly in a hangar in the Innovation Park in D\u00fcbendorf. Their ambitious goal: is to construct a light aircraft that is entirely battery-powered. “Flying harms the environment. But there are still no good alternatives to aircraft powered by kerosene,” says Anna Thumann, a mechanical engineering student who has been involved in the project from the start. “As a team, we\u2019re motivated by the goal of contributing to a more sustainable air industry.”<\/p>\n\n\n

Just like everything else, the aviation sector needs to do something about its emissions. Aviation companies and countries have gotten together to set ambitious goals.<\/div><\/div><\/div>\n\n\n

Modular battery<\/h2>\n\n\n\n

In addition to an efficient electric engine, the students developed a modular battery system with a special cooling system. The biggest challenge was achieving the required energy density for the battery while keeping it as lightweight as possible; when it comes to flight, every gram counts. So that they didn\u2019t have to come up with an entire aircraft design alongside the complex drive system, they made use of an existing design: a kind of construction kit for light aircraft from the South African aircraft manufacturer Sling Aircraft served the students as a shell. After a few adjustments, they built it themselves and fitted out the aircraft with their technology.<\/p>\n\n\n\n

e-Sling is the first electric aircraft to be equipped with a modular battery system. This means that the batteries can be exchanged during a stopover \u2013 although in practice this currently takes some time.  In future, uses for the quiet aircraft could include monitoring national parks without disturbing the animals. e-Sling currently has a range of around 180 km. <\/p>\n\n\n\n
