    Conceptual design focusing on the ability of a redundant electric propulsion system to provide new capabilities for Vertical Takeoff and Landing aircraft. Specifically utilizing electric motor variable rpm to accomplish a low tipspeed prop-rotor (400 ft/sec tip speed at hover and 200 ft/sec at cruise) to accomplish an order of magnitude reduction in community noise for close proximity operations (30-40 db reduction). The variable rpm capability also achieves a 25% improvement in prop-rotor efficiency through operation at optimal advance ratios.

    That would work brilliantly, If it was permanently plugged into the mains.

    Not gonna work practicably. The weight of batteries alone for this thing will be about the same as a jet and fuel. The range with that weight will probably give you about enough distance to go to the coffee shop and back, before the bunny stops banging the drum! Cool concept but not feasible.

    Fantastic! I'm specially keen of how it comes back to landing position, it works just like a pendulum! Instead of stalling at low speeds, the center of gravity, which is in the tail, does its work and gradually raises the rotors to keep lift. Congratulations to whoever thought this out, it's very simple and creative. The only weird thing is how the cockpit is set up: looks rather uncomfortable and neck-aching.

    @jasonharville1 nasa probably has access to far higher tecnology than those of a mere cordless drill.

    @NASAPAV V22 Osprey.

    Nice design. Neck ache could be a problem when flying horizontally though.

    looks really badass.

    Hi NASAPAV, brilliant design. I personally love the design and think that even with current battery constraints that your design is feasible. It is definitely about power to weight ratio in this case. Have you considered multiple battery packs from the cordless drills. They are plug and play, fairly light and can be arranged on both sides of the pilot vertically for correct CG. Also with a stator ring underneath each prop for charging... I.E., similar to the charging system on a lawnmower.

    @NASAPAV Talk to me when you find the money just to finish drawing this thing that seems like an helicopter ! There are so many of this things that all end up looking all the same, but what they have in comun is all of then are waiting for some rich guy to put all his money into it and never see it again ha ha ha !

    but in case of emergency.. what is the  action course?

    Really? Do you know what the Lift/Drag ratio is for a helicopter? Between 4 and 5 - incredibly inefficient devices. Do you know what the L/D of this aircraft is? At 100 mph it's 17.5, at 150 mph it's 14.5. So about 4x the aerodynamic efficiency. Do you know how complex a helicopter rotor is and why heli's are so expensive? The hub mechanism on this is incredibly simple and low cost. Sorry, not quite...

    We have something better working already it is called HELICOPTER !!

    landing this thing will have to be on auto otherwise its just a guessing game. the pilots's position in the cockpit is not natural therefore its a no no

    You are correct, it is much more difficult to attempt several changes all at once. But the electric completely changes the VTOL design, and has to be done in combination. Prone doesn't really complicate things in terms of integration - it really just becomes a comfort and pilot acceptance issue, and isn't a factor in the sub-scale R/C versions we are flying.

    there is no lack of cool CG animation in aircraft design, specially in the VTOL category. :-) Putting electric, vtol, and a prone pilot position all in one vehicle in one go, sounds pretty risky to me....one at a time.... do a uav

    @NASAPAV is this going to be available to the public? in all countries? also what will the price be?
