I have a New concept in VTOL "Tilt Fan Technology"

I have a new concept in VTOL "Tilt Fan Technology" there are two ways to design a VTOL Bike or Car type of vehicle that uses that type of Tilt Fan drives for both Vertical and horizontal flight modes one retro style is the radial concept five electric motors rated at 68 amps configured with four in a cross or X style interconnected with the Ducted fan on top along with the fifth one attached below the tilting hub powering the smaller ducted fan that has Pitch/Roll vanes.Concept two-Prototype stage VTOL Bike using five electric motors also rated at 68 amps one powering the counter-rotating rear duct-fan with yaw control vane and two with hub in the front,and rear of bike.
I haven't finalized designs yet,but I wanted to get some feedback on the concepts that I've outlined in this post.

Well thats all for now, I might put some images later.

Dunno where you're getting the 68 amp figure from, but 68* 5 is 340 amps of current. For simplicity, lets assume they are 12 volt fans. You're talking about a shade over 4 kilowatts of continuous draw at max current. What are you gonna power this vehicle with and what what to you expect its range to be?

I'm not saying the problem is insurmountable, I'd just like a better idea of what you're cooking up. It sounds like a larger scale version of some of the small radio controlled flyers I've seen on the web.
 
I've got a 5-foot wingspan electric R/C biplane that pulls 45amps just to fly normally, and it only weighs 5lbs.

...don't think you've thought through your power requirements...

(BTW: This is why Moller is such a loser. Every time he puts out a design he underestimates how much power he'd really need for one of his VTOL cars by 5 times... But he has been able to scam a hundred million dollars from stupid investors over the past 40 years.)
 
Alpha Geek,The 68 amp motors are being used for large scale R/C models such as the Airbus R/C model jet Aircraft,and Boeing 777 R/C Models lifting a 150lbs of model aircraft into the air all I'm doing is adapting that technology along with tilt rotor systems that are R/C controlled in the cockpit,and BTW I'm using LIPOLY Battery technology along with PVC wrapped in Carbon fiber,skinned in mylar carbon sheeting for a light weight structure that will fly if I could find someone that is skilled in creating R/C aircraft then we could work together I'm simply the visionary and designer I just need someone with the technical knowledge to pull it off.

Right, but those models rely on large horizontal planar surfaces with oh... what was that guys name... Bernie?.. Anyway most of the lift for those models is produced by those planar surfaces, unless you can stand the thing on its end and it hovers on thrust alone.

Lithium-Polymer is about as good a source of power as you're gonna get.

What's your design do in the event of a fan failure?



Bernoulli!
 
If I was to use the Radial engine design 5 such motors per thruster four in a "X" horizontal connected to a rotor hub by a nylon gear power hub to the rotors should in theory transmit the total output of all four motors if one should fail the other three in each thruster will take up the slack,the fifth one is only used for hover flight,and directional control.
the landing gear is a four point system with the main gear folds up like the P-51 Mustang positioned mid-craft with two retractable nose gears up front,again R/C controlled. I tell you the vision that I have of the completed craft is amazing its just too bad I'm a broke visionary that does not have the funding to make this happen.

Well I hope I've explained a little better of what I'm trying to do with my design/concept it could revolutionize personal transportation as we know it.

Good night

Well since you're citing R/C parts as a basis for the design, it should be easy to come up with a scale model for proof of concept at not too great an expense. :)

I know that tonight I'm going to have nightmares about the TV series GALACTICA 1980.

A) Nylon gearing is not going to hold up under that much power.

B) Gearing the motors will induce losses from the friction of the gear mesh.

Far better to build multiple ducted fans with a single motor in each fan.

Current R/C electric ducted fans are pulling up to 10KW and powering jets going nearly 200mph.

....but what you're proposing still won't work yet.
 
Thanks Alpha.but RD money is scarce right now I'm unemployed so as soon as I'm working,and I'll put out the funds needed to get started. Household bills come first.

Hehe. "no bucks, no Buck Rogers"

Buck I think you missed the part of the conversation where it was mentioned that those 150pd R/C models get all of their lift from the wings. The motors just provide forward movement to get the necessary air moving across the wings. If you ripped the wings off and turned the engines to point exhaust down, those planes would not fly.

No I did not miss the point I'm not using long wings with engines attached under slung,but at the tips with short stub wings those tilt.

P.S.: look at my design OK.

Yes. I looked. Even based on your simple drawing I think it's safe to say you will not generate enough lift. Simplified, your maximum liftoff weight cannot be more than the thrust of all of you engines if you are relying on them to provide all of the lift. You need to study some basic aeronautics.
 
I've been busy working on a new design using one counter-rotating Horizontal thruster,and four tilt-rotors to create a flying hover cycle until I refine it I won't post another image for this topic.
Plus I've been very busy Job-hunting so time for uploading designs has been few,and far between.
