A Second Flight Campaign Filled with Firsts | SolarStratoshttps://www.solarstratos.com/en/2026/05/newsletter-115-en/Over a 3 km out-and-back course, the aircraft reached a maximum ground speed of 154.7 km/h, which would translate to an average speed of 136.6 km/h, to be retained in case of homologation. “This is quite a success because the aircraft’s maximum speed is 140 km/h. That means we got very close to this maximum speed without ever exceeding it. We aimed for 130 km/h and achieved 136.6 km/h: that’s really good,” rejoices Raphaël Domjan.
Nicméně, zatím to zabalili, zvážili letadlo bez baterií (legrační, že to dosud neudalěli!) a připravují se na "další evoluci". Jinými slovy: tahle verze by do stratosféry nikdy nedostoupala :-)
