  • air intake would be a problem as others have noted, along with the torque of the motor either throwing the nose up or down depending on how its mounted and throttle position , interested to know how it turned out . any updates?

  • You suck the air under the wings that would never work, can't believe you didn't notice that

  • @DieRedo

    Yeah, having the intake under the right wing would disrupt airflow and would create low pressure under the wing killing the lift from the low pressure air flow over the wing.

    You could have the intake facing fowards, but then you would have a normal ducted fan engine.

  • An example of know just enough to be detrimental. The idea has been done, they're called the turbine and jet engines. A leaf blower won't work, there's not a high enough power to weight ratio. If it could work, then leaf blowers wouldn't be stationary while blowing. They would fly out of your hand.

  • I am very happy to see the vidoe after you give this This is an idea I had after taking apart my broken leaf blower. I plan to build the RC version of this come summer.

  • I Love The Video It Can Increase My Knowledge This is an idea I had after taking apart my broken leaf blower. I plan to build the RC version of this come summer.

  • Your Video This is an idea I had after taking apart my broken leaf blower. I plan to build the RC version of this come summer. Is Very Useful Sharing

  • Hey! good idea, but your blower fan is backwards in this depiction. To get the maximum amount of thrust, the fan should be flipped around. The centrifugal force of the air being pushed through the blower will make it accelerate when inverted.

  • lol this was my idea in grade school for science fair.....teacher siad told me it was cute....

  • Good idea bud, but you really need to consider the centrifugal force when trying to turn.

    While you have your blower going hold it out in front of you and rotate it left or right quickly, then get someone to turn it on and off quickly while doing the same thing. You will be surprised how much it kicks....Keep going though I love the idea.

  • where will you get the very long drop cord?

  • awesome idea too bad it wont work like that how ever i have the answer while all the people saying it will roll over do to the intake are correct make it as a twin engine to even it out and double the power perfection :D would love to see it fly its a cool idea man

  • the rules of aerodynamics man, what were you thinkin

  • cool idea but your fins are reversed on the scetchup.

  • What about power and weight ?

  • So basically it's a car turbo with wings. Cool idea though. I like it. :)

  • I wonder what will happen with the gyroscopic mass. What about two thin blowers counter rotating in the same housing.

  • I wonder what will happen with the gyroscopic mass.

  • LETS SEE THE FUCKER FLY THEN YA CUNT !

  • @MarquisofHumber

    Wow you're obnoxious. Thanks so much for posting that.

  • The 1st thing that comes to mind when seeing this would be to strap a leaf blower onto a small r/c boat lol

  • The sucking form one side won't work , just constructive critisizim

  • I think as long as it sucks air from both sides it should probably fly. It might need a longer tail rudder.

  • bizarre

  • you need to Chang the sucking hole to another way so when it sucks it doesn't suck the sucking will pull it to a side

  • Been done. Search for "rdrc flying leaf blower" here on YouTube.

  • Comment removed

  • I have one

  • I said sit

  • Sorry I ment to say sit

  • 2 problems I see here. First the air intake will be from the side. If this design were to fly the low pressure created by the suction of the rotating blades would pull the plane towards one side. Much like a normal rudder would. You would need a counter balancing fan sucking from the other side too. Second problem there will be a lot of drag with the fans sucking from the side. You would want an air intake the gides the flow from the forward direction of the plane to the intake.

  • @narlzp what about the centrifugal force of the fan?

  • Where's passengers sit

  • @soccerfighter13 where's passengers shit?

  • I saw one fucker here on Youtube fly one, I think it's; (Flying a Toro electric leaf blower )

  • And how are you going to power it? A long extension cord? Do they make battery powered leaf blowers? What is the weight of battery power compared to thrust?

  • nice work!  thanks.

  • Sweet, What size/speed brushless motor would you use for this? 

  • Comment removed

  • it was already done by a man in Raleigh, NC. It actually flew very well by the video i saw on the news!

  • LOL yeah that'll never work

    especially with the intake on the side like that...and even if you did find a way to make it work, it'd take way way way too much power to get airborn / be too loud etc

  • i think none will work.

  • I have an idea that might make things work... Take the blower, and add to it another one, that is oriented entirely oppositely (it might have to be a custom-built job) now turn the whole thing on its side (both are pointed backwards, both motors are pointing up, but both sets of blower blades are rotating in different directions)

    I don't know if that would work any better, or if it would just add extra weight to the system, but I'd expect better thrust/stability

  • no it wont work cause all that air sucking in from the side will pull it to that side

  • awesome ! nice post

  • cut out scene from

    the adventures of baron munchausen

    I LOVE IT!!!

  • One of the key reasons propellers work so well is their power to weight ratio. Also when the propeller pulls are through it, it then blows the air over the wings, give more lift to the aircraft. So the amount of power required to make an aircraft like this work, would be similar to a small jet engine, and it also depends on the aircraft's wing span and weight.

  • Interesting idea, but the intake being at the side and under the wing will deplete the higher pressure zone under the wing, reducing life by some degree.

    You could add an intake shroud that ensure that air is taken in at the front of the aircraft to do two things -- 1. eliminate any effects of the intake on lift, and 2. gain whatever efficiency you can by taking in high pressure air at the front of the aircraft. This will increase net blower pressure and reduce overall drag.

    Good luck...

  • No, wait. You're going to power this with a jet turbine, right? The jet already blows back, so why bother with a squirrel cage?

  • Why not move the Intake to the Front,would be more efficient wouldn't it?

  • Any progress on this?

  • You are going to need better wings than what I can see here but I can imagine you know that already

  • where is the video of this thing flying?

  • Tweeker put the blower down LMAO

  • clever, but how exactly do you land that?

  • everyone is getting all technical overlooking one simple thing. power supply .batteries itll be to heavy. and i doubt it will fly when attached to a cord either.

  • @drsta84 they have power supplies/batteries with current RC planes...

  • @nicanor76 Yes, but the propulsion system is more efficient than this and also needs less power to operate.

  • Good idea.Why dont you make a blower at both ends and force air at a bit downward angle?.That may lift the aircraft upwards(VTOL), and by changing the direction of the thrust flow, you can climb, decent, or turn.

  • Looks great - but will it fly?

  • You will need to make the tail surfaces bigger and / or further rearward. The reason being with the large disc blower at the front you will need much more surface area at the back to balance out the effect. Otherwise it's like taking an arrow and sticking a larger surface area on the head than the tail fin and expecting it to fly straight.

  • do you think the centrifugal forces of the propeller would effect the aircraft when it's turning?

  • @gdykes yes greatly, could be benifitial though if planned for

  • You know you could export your sketchup model, import it into x-plane, assign all the real world data about torque, horsepower, weight, wingspan, etc and see if it will actually fly. Test your models first before deciding on a design. Rutan, I know, used to use x-plane for this and it's an exceptional modeling tool as well as a decent flight sim.

  • Sweet idea....but.....I assume the intake is off the side wich would cause a problem in flight.....and the gyroscopic forces created by the rotating propeller would never let it turn in flight.

  • Hmmm.. It seems very possible and is an amazing idea :)

    God, I love sketchup I just recently started using it, its great to show your ideas that would be hard to try without a 3d model.

    Otherwise nobody will see what you see in your mind :)

  • Where have i seen this? oh yes, on fighter jets with jet thrusters that use flame to propel the planes instead of air. Haha you are starting at step 1 of where the engineers started. :P

    one thing, the weight would also bring the large circle down along with the rotation. another thing to consider.... would be cool to make this into a working rc plane. haha

  • Hi guys

    This type of plane propulsion was available as a plan with model and all in 1951. I have a copy of the plane wich was named the blowbug. It was powered by a small glow engine. Flew nice and made a funny sound. It had the airopening on the top in the "canopy".

    Good luck with your version.

    Best regards

  • cool! I've seen a hovercraft made out of a blower...but an airplane.....i think you'll need a very strong motor to get lift out of that which usually comes with a lot of weight...

  • wheres the power source? Petrol electric? I would put an elbow on the inlet so it sucks air forwards, or it will fly diagonal. Better still have two running a common motor in a central fuselage. Get a edge trimmer petrol motor to power it. Nice idea.

  • Ah, but how about a twin-blower, counter rotating model... flip the blowers on their sides, intake up for added suction/lift... Or flip that arrangement over, reverse the fans, and make a hovercraft. :)

  • ha! i'm a steal your idea and build and test fly before you!!!

  • that is briliant! imagine if you could get it to work thats 1. step 2 make it work on electricyety step 3 make it into a giant scale this could be enviormentaly briliant. im impressed.

  • Wow, thats an original idea. It will be interesting to see how this all works out. Good luck with your idea, I hope you get it flying!

  • Nice Mark! I think it would work real good if you had two - mouted horizontally. (Think wings!) Face the intakes to the top of each wing and then you would take advantage of the low perssure as potential lift (and help balance the plane out.)

    When I finish the "Goose Project" I'll check in again to see if you've tried to build this. If not, hmmmmm, maybe next for me? (I think the idea has merit!!)

    Thanks for the videos! Keep 'em coming.

  • cant wait to see it fly. nice sketchup work.

  • attackangle , good idea I will see how she flies this summer and I may have to go that route.

  • @kram242 theres one thing wrong with this that i can see, the motor will add resistance on just one side, so it will pull to the left

  • I 'm thinking that the air intake side will have an area of low pressure at the intake creating a pull to that side of the plane. Solution: a duct pointed forward to draw air from the direction you want the plane to go.

  • hmm pretty cool idea, but idk if it will work.

    should be interesting

    thanks for sharing
