Flying car, or whatever we call them these days.

This flying car concept is based on a scaled up version of our hoverbike which has a small scale working prototype. Featuring a monocoque frame and redundant propulsion, this flying car concept is roughly designed around the eight rotor propulsion systems of aircraft such as the Ehang 184 and the Workhorse SureFly, based on the limited information available.

  • Roll is stabilized by lateral forces which rotate the vehicle around the center of mass
  • Rotors are mounted at angles to produce roll stabilizing lateral forces
  • Requires only eight motors, no additional moving parts, actuators or control surfaces
  • Fully redundant propulsion system can operate safely after a motor failure
  • Rotors lift the vehicle directly, eliminating the structural challenges of conventional boom and rotor set ups
  • Monocoque, carbon fiber construction is lightweight and rigid
  • Compact footprint
  • Small, streamlined profile for increased range and speed

Nice

I like it, a lot. Do you think a two passenger version could fit inside of a single car garage?

It looks like the unique critical issue is making sure there is enough roll authority to overcome all possible internal and external forces. I'm pretty sure this would be determined by the tilt angle of the motors. Perhaps in a future version the tilt angle could be actively controlled.

Also in the future with a powerful enough rearward facing thruster, the motor supports could become airfoils and really increase the speed and range.

I will not even bring up the obvious submarine resemblance except to say I think this design has a lot of possibilities and desirable characteristics.

Hi John, this one comes in at just over 21 feet, so yes, it would fit inside of a single car garage. Roll has never been much of an issue. I thought it would be. Smaller rotor angles mean less roll authority, but also lower PIDs. I had a 5 degree prototype that was rock solid on default PID settings, until you tried to corner. I think any lifting surfaces sufficient to sustain the vehicle would interfere too much with roll authority during hover. I would hate to resort to active tilting. There just to many added mechanical components and other factors.
