Hello all,

I am working on a VTOL concept and thought I would post it here.  I hope to get as much feedback as possible from anyone who has any.  The depicted airframe is the simplest embodiment that would be capable of both rotary and fixed wing flight.  Alternative versions could look very much like a conventional helicopter having a stationary fuselage and a very small tail rotor or control surface.  This is basically just my website copied and pasted.  This is a concept only at this point, no prototype. Also, the ducted fans were just for simplicity for the animation, not necessarily for the working aircraft.
Thanks for looking.

- Joe

  • Just posted an update to this design here, please have a look and post some follow up comments.  Thanks!

  • Hi Chris,
    I love their design, it is the design I think about the most when working on my own, and has been the biggest inspiration and source of validation since I started designing my concept. The first thing I did after thinking of my concept was hunt down their website, I knew of their design, but could not remember their name. I have probably looked at their design everyday since. That is really interesting that you were able to work with them. Was that before they were working on the Pathfinder?

  • Thanks for looking Martin...
  • Sorry Joe, I was not able to find the link. It was posted somewhere in RCGroups.

    Anyway, I think your idea could work.

  • Hey Mike your right, a very small rotor would be enough, or even a control surface. During forward flight a stabilizer would be more than enough. Thanks for those videos Gary, I have seen Lockheed's but the first two are new to me. I have a few more links to similar aircraft I will post today.

    Jack Crossfire is your man for things rotary and unusual

    It was efficient on very small batteries

    and then Lockheed Martin caught on

    Ah all back in 2010BD happy days.
  • If the rotor is powered (i.e. motors that power the rotor are on the rotor), you dont need to cancel out of a lot of torque on the fuselage-- you just need to cancel out the torque due to drag on your joint between the fuselage and rotor (bearings and wires). 

  • Hey Sergey, for variable payloads you would have to distribute weight fairly well. That would be a good case to use a tail rotor to keep the fuselage stationary. Also, designs similar to this have a very low rotation speed, as low as one rotation per second, so vibration or wobble would be reduced.

    Folks...We discuss about most idiotic concept I seen last years on DIY Drones. :))) Lot of fun, but this ... NEVER fly.
