Two-Seat Electric Plane Aims To Break 80,000 Foot Electric Flight Record
July 26th, 2018 by Nicolas Zart
Electric high-altitude flying is still something we haven’t written much about. How about 80,000 feet (24,400 kilometers) in the sky. That’s what the electric solar airplane Mission SolarStratos is all about?
First Solar Two-Seater Plane Aims to Break 80,000 ft Record by 2020
Solar flight has already pushed boundaries, with flights around the globe — all the way around the globe. But flying twice as high as the highest commercial jetliner using the sun’s energy is the next frontier. The Mission SolarStratos expedition hopes to meet that target within the next two years.
Mission SolarStratos Specs At A Glance
The Mission SolarStratos was designed by Calin Gologan of Elektra-Solar GmbH, and is also a technical partner on the project. The e-plane stretches to 8.5 meters, roughly 30 feet, with a wingspan of 24.8 meters, about 81 feet. It weighs 450 kilograms (992 lbs). In order to save on weight, the cabin won’t be pressurized and the pilots will wear pressurized suits using solar energy.
Technically, the electric motor produces up to 32 kW, powering four 2.2 m blades at 2200 rpm, with an efficiency of 90%.
It uses 22 square meters of solar cells to harvest solar energy, each reaching 22% to 24% efficiency and feeding that electricity to a single 20 kWh lithium-ion battery. This gives the Mission SolarStratos an autonomy of more than 24 hours.
According to SolarStratos President and Pilot Raphael Domjan: “SolarStratos has an opportunity to push the limits of what we think is humanly possible and prove that renewable energy has the capacity to power our lives while preserving our planet. We are fortunate to energize SolarStratos with SunPower’s industry-leading solar technology and look forward to further showcasing the value of innovative and reliable solar solutions for the world to see.”
Why Fly So High On Electricity?
This experience pushes the limits of high-altitude electric flying. Sure, there was the Solar Impulse 2 and even PlanetSolar, an impressive solar energy catamaran. Now we are going for the stars, almost.
