This is NOT a Propeller

The HD cam on the plane was a Mobius Action Cam amzn.to/2nxTSR7
But I also recommend this newer more rugged one www.gearbest.co...
Or amazon amzn.to/2odcHMw
So I made a centrifugal fan.. And then built an airplane around it
Bonus footage: • Video
For clarification: I did not use the AC motor from the heater, but rather I put the impeller onto a much more powerful BLDC motor as commonly used in RC.

Could you, by mounting the fan horizontally with the air intake at the top (with the right design) lower the air pressure on top of the craft and increase the lift?

[@kevinsbudchannel3668]

Both your ideas would work, and have been used in aircraft designs several times. The MD NOTAR System works a lot like that for lateral control (The actual torque compensation doesn't, though, only the rudder does.) and some STOL capable transport aircraft have their engines on their wings for that reason. Or think of the Honda Jet, or from back then, the VFW 614.

The greatest advantage of this would be for safety.

Imagine a scenario of a sheer cliff rescue. With a copter, the pilot has to worry about rotor contact with the cliff face; where as a rotor less craft avoids this issue.

[@dafrandle]

and would require way more power

[@lordhood117]

dafrandle Power requirements can be reduced with careful engineering. For example, giving the exhaust a properly-focused nozzle would create a Venturi effect, boosting the thrust output a bit thanks to Bernoulli's Principle.

[@dafrandle]

(i should note i'm talking about the helicopter part) to get the same performance it would most likely require at least a little more power because we trade the usage of lifting surfaces (the rotors) for thrust that we must create all ourselves, it can be done (just look at the harrier) it just not practical -- or we would have adopted it already

[@SammSheperd]

+Lo3 Yea, it is a sensor that senses rotation. When the plane is rotated, it automatically applies corrective action on the appropriate control surfaces (assuming you set it up correctly). The unit also lets pilot control inputs through. This instantaneous reaction helps to smoothen things out

That space in the blower is called a plenum. If you look that up you can dial in the most efficient shape, although you got pretty close it looks like. Squirl fans are very effient as fans go. Lot of advantages for not having a prop. Very durable and more placement options for the propulsion.

[@fabiovezzari2895]

I read that centrifugal fans on planes are efficient and powerful at low speeds, but also that they consume more energy from the batteries. Do you think it's true? I knew it from a guy on a forum and probably they are just intuitive considerations.

[@bradyspace]

The statements seem conflicting. It seems like there are tradeoffs like many other plane configurations. There are more blades and more surface area around the walls of these blowers vs a prop that is getting clean open air. However the blower with enclosed air can be compressed and further utilized. Similiarly at certain speeds jets become more efficient than props.

[@mariopuzo4509]

Well played sir, that is pretty ingenious. As with EDF's there are a few critical tolerances with regards to inlet and outlet size (and in your case impeller to case clearances), with some study, expirementation and refinement, I'm confident you could significantly increase the efficiency. Also the reason for pitch up under power is the thrust line(outlet) below the center of lift and gravity. If you flip your outlet to the top it would move them closet to one another and provide moving air across your tail surfaces.Keep up the innovating, now if you'll excuse me I must go strip the a/c blower out of my old car...

So, uhh, not to be a party pooper or anything, but I REALLY don't recommend flying RC planes at that airstrip anymore, because that is sort of an active runway for emergency landings. I would know, because I've landed there..

[@SammSheperd]

+lolsoar This is CA66, a private runway. I am a commercial pilot myself, and I know the local traffic very well.

[@lolsoar]

+Samm Sheperd (SNRS) Ehh, private or not, I still wouldn't want to fly any RC planes anywhere near it.

super good work, and ingenuity. I scratch built tons of foamys in my life, probably destroyed 80 planes. But foam is easy to repair or replace. Always back in business the next day!

[@snipereliete]

Mate that was awsome,well done.in 30 years of flying and involved in the hobby I've never seen anything like that.it is indeed a turbo motor.because the turbo on my old car was pretty much the same thing.the plane had plenty of power and was very power efficient and reliable.the plane was also well balanced,with is the most important thing.props to u my friend,awesome job.big hi from Australia.don't ever stop flying.it's the best hobby in the world.

I would love to see 2 of the ducted fans set with the motors to the inside and the intakes facing each other and then ducting into the intakes from the nose area and then maybe exhaust above the wing on a wide body airframe and I would think that the weight of cargo it could carry would be huge

[@mojoneko8303]

I was thinking the same thing! :)

Rest in Peace Sam buddy. You will be missed by many.

[@themuseicman]

VTOL potentially? Directional thrust vectoring as well?

[@SammSheperd]

Not enough thrust to weight but that would be cool!!

[@ur_quainmaster7901]

@@SammSheperd you could do super short take off if you designed the "blowie part" to go directly over the wings.

[@jamesd6801]

Totally cool! Just needs a little more power

[@fryncyaryorvjink2140]

I've been thinking of making a drone like this, pull in air from above and shoot it down through pipes slightly angled to counteract gyro from the impeller, but also thrust vectoring

[@aidenokrent]

Nabre Labre VTOL has done this I believe.Google it for help in a pinch.

[@jflow5601]

What a gifted guy. I see below that Samm is gone? OMG I am sad.

[@talkinghat88]

Amazing skills! Was surprised by the power of the turbo. Must say the use of the weigh scale to measure thrust was very smart. Thanks

[@truthseeker7192]

You live in a beautiful place, I'm jealous.

[@brookestephen]

I'm hoping to do the same with a single-passenger ultralight! Nice proof of concept!!! Wish me luck. BTW wouldn't the efficiency improve with the exhaust ABOVE the wing, leading to more speed and lower pressure on the top surface?

Rip I can’t believe even today I can’t find a plane that uses a centrifugal fan

[@thejoshmoss]

Ok, that kicks ass, I didn't think it would work at first but it flies like a dream! have you seen the videos Matthias Wandel made about him making a wooden blower to match a motor he had? It's just for a shop dust collector but, he gos into a lot of the science. also, I've herd people call bower fans like this "squerrel fans" or "hampster wheel fans" could be a good name in that..

[@SammSheperd]

+Josh Moss Yea actually I think having seen that is what made me think about making this when I replaced my heater

[@MikeSVOR]

I would change a few things. Your wing incidence ratio is way off. Make it closer to the tail AoA. Your ability to make exhaust velocity is not being taken advantage of. You need to narrow the outlet which would raise the air speed coming out of the exhaust. Treat it just like an EDF. Widen the exhaust outlet and you increase traction but decrease speed. Narrow the outlet and you decrease traction and increase speed.

[@SammSheperd]

+MikeSVOR I agree with you. The angle of incidence is a bit high, resulting in a little bit of a nose low cruising attitude. The decalage is also a bit high, resulting in an inherently stable, but slow trimmed condition and excess elevator drag at higher speeds. When I experimented with narrowing the discharge nozzle, I found that it was not able to pump as much air, and would not consume as much power. Though I did not try to measure the thrust in this condition, it felt to me like there was less. I am interested in asking engineering professors at my school when I get back about what centrifugal pump design would be best for thrust. And I would like to model and 3D print a much more complex one which I imagine will resemble something like a turbocharger.

[@user-ly7fx7rx1l]

Makes sense

[@robbylebotha]

I love it when people don't use jargon but still get the job done.

[@hotrodmercury3941]

Building one of these, I made the design more streamlined. I live in a rural area and cant wait to fly this thing when I am finished with it.

[@hotrodmercury3941]

The design this thing has I would like to note, is more safer then traditional builds. You discovered something that hasn't been really thought of before. The moving parts are inside, making it safer if it were to collide with the ground or god forbid someone! Will update on the build though!
