Joby Aviation’s S2 concept expanded from its two year collaborative study with NASA that resulted in the NASA GL-10, Joby Lotus and joint NASA/Joby LEAPTech concepts.

The S2 would feature 12 propellers on tiling and folding nacelles with eight on the fixed wing and four on a V-stabilizer/rudder configuration. Aside from accent and decent these would tilt laterally and the blades fold back to reduce drag. Four additional fixed horizontal pusher props on the wing and stabilizer tips would be utilized for cruising. The vehicle would have been all electric and designed to carry two passengers.

Joby has discontinued the S2, using data derived from it and its Lotus demonstrator to work on its four passenger Joby S4.

In May, 2018 the Vertical Flight Society presented Joby Aviation’s CEO, JoeBen Bevirt, its Paul E. Haueter Award (given for an outstanding technical contribution to the field of VTOL aircraft development other than a helicopter or an operational vertical flight aircraft) for successfully demonstrating the world’s first high-speed multi-passenger electric VTOL aircraft.
