SolarStratos is a two-seat, single-engine Swiss electric aircraft that is scheduled to perform stratospheric flights in 2018 .
history
Initiated by Raphaël Domjan , the SolarStratos electric motor glider aims to significantly surpass the previous altitude record for solar-powered aircraft of 9,235 meters. The financing of the project, which started in 2014, is based on crowdfunding . The rollout of the prototype took place on December 7, 2016 in Payerne , the first flight on May 5, 2017 with registration HB-SXA.
After a two-hour climb, fifteen-minute stratospheric flights are to follow in 2018.
construction
The constructed by Calin Gologan and the Elektra-Solar GmbH in Hurlach built two-seat low-wing aircraft wings has high elongation , a normal tail and a spur wheel chassis. It is made of carbon fiber composite construction and has no pressurized cabin . Pilot and passenger sit one behind the other in Russian Sokol spacesuits . At CSEM in Neuchâtel, the upper sides of the wing and tailplane were covered with 22 m² of solar cells . A 32 kW electric motor in the fuselage front drives a four-bladed propeller, the lithium-ion batteries from the Austrian manufacturer Kreisel Electric weigh just 80 kg with a capacity of 20 kWh.
