L’aereo a energia solare SolarStratos ha effettuato oggi, venerdì, il suo primo volo nei cieli sopra a Payerne, pilotato dal collaudatore Damian Hischier. Il velivolo è arrivato a 300 metri di quota e dopo sette minuti è atterrato.
L’obiettivo è di entrare entro il 2019 nella stratosfera a oltre 24'000 metri di altitudine, un traguardo impossibile da raggiungere con un apparecchio a propulsione classica. Lungo 8,5 metri, ha un’apertura alare di 24,8 metri, pesa 450 chili ed è ricoperto da pannelli che gli consentono un’autonomia di oltre 24 ore.
Ideatore del progetto è il pilota Raphaël Domjan, noto per aver realizzato nel 2012 il primo giro del mondo con il catamarano PlanetSolar, mosso anch'esso dall'energia solare.
