Because of the fact that these centrifugal designs usually produce a significantly good pressure when allowed to flow, did you try reducing the diameter of the outlet nozzle at all? I know more air flow is desired but I was thinking just the rear engine with the higher velocity flow and keep the front on with higher volume?

[@scott_aero3915]

So, knowing that the intake position is not particularly sensitive to location, you might be able to gain some advantage by burying the centrifugal fans inside a wing with a top surface inlet and exhausts below/aft the wing. The low pressure may well contribute to overall lift. Thinking about this a bit more, over the course of the day, I would suggest you could have an upper surface inlet inboard, close to the fuselage, if there is one. You may require a fence outboard of the inlet in case the low pressure zone disrupts the outboard flow. The other thing you could do with this (and it could be impractical at this scale....) is to use the jet exhaust as a trailing edge jet, rather than as a propulsion system. This could act as a jet flap and encourage flow attachment when it would otherwise break away - boundary layer control. This has been tried on a few aircraft over the years - today the Shinmaywa US-2 uses a separate power system to generate flow for BLC on flaps, rudder and elevators. Another aircraft to look up is the british Hunting H.126 which was used to investigate these systems.

[@winterwatson6811]

would be cool in a flying wing

[@durgstudios6511]

So in static testing no. But in flight there's "ram recovery". The air rams itself into the intake making the impeller more efficient

[@lukearts2954]

would be interesting to test this, because some aeronautical engineers claim that the lift is produced by the reaction force that results from the airflow leaving the wing, not the old concept of low pressure above the wing. If air is sucked away from the top of the wing, it might reduce the pressure there, but it will also reduce the amount of air flowing off the wing. If the old concept is right, then the lift should be improved, if the new ideas are right, the lift should be reduced (provided the air intake is relevant compared to the total wing surface).

[@danielc2701]

@@lukearts2954 Isn't the airflow leaving the wing called the Mach Tuck? Rather than lifting the plane, it changes the CG of the plane enough to cause it to nose down, causing quite a few air crashes in the past. Modern planes have features to prevent this these days so if that claim was true, these modern planes would have had less lift than those in the past but you don't see this, so I'm a bit skeptical about that claim.

[@ast_rsk]

This was so fun and impressive. I was kinda dying at the asymmetric mount to get your center of gravity/lift to be right. Since you have a 3d printer, next time you do this and it needs 2 motors, just print an inverted flow unit so you can mount the motors on the left and right of center line for the craft (in forward direction)! But seriously, this was awesome and the bonus destruction at the end had me stunned!

[@chb072353]

If you match the desired speed of the airplane with the area of the inlet with a gradual (low loss) cross section reduction from the inlet bell to the impeller vs the same mass exiting the fan system you will minimize inlet losses and maximize available thrust. Keep in mind that the fan you are using was designed for high inlet velocities with no restriction. Create a ram inlet to maximize the aspiration volume and minimize the aspiration losses . Likewise, the outlet nozzle should do some flow straightening to get maximum impulse, and the area ahead of and outside of the nozzle should be tapered to allow the ambient airstream to gently return to fill the void created by the engine cross section avoiding turbulence rapid shear at the trailing edge. You end up with an aerodynamically efficient engine housing and an efficient energy transfer. Remember that an inlet to a fan that is "starved" will produce less net gain in pressure and therefore a lower exhaust impulse (MV2). Spend more of the energy compressing and accelerating the air to maximize the V2 component of the MV2 formula at the outlet. It will always be true that the M portion is the same for the inlet and the outlet. (conservation of matter) so look for lower V2 at the inlet (larger smooth intake) and highest possible V2 at the outlet. This all would be best achieved by placing the motor with its inlet axis the same as craft direction of travel and then using a bell housing around the motor outlet to collect and compress the air as it moves rearward towards the exhaust nozzle. Voila..electric jet engine. Forcing the air to spin around the volute (many times) instead of moving directly to the outlet with a single turn burns energy as friction and heat.

[@shanesdiy]

Cool project! Worked amazingly well. I wonder if any gains might be had if you line them up to get a little compound thrust by pointing the outlet from the front motor towards the inlet of the rear motor. Not up close but in the thrust path to give it a little forced induction.

[@comandoaec]

Because It acts as a centrifugal compressor, build an afterburner, increase the thrust and burn some fuel ;)

[@bluerider0988]

Glad to see someone else make the point on vacuums. I've told people that the motor speeds up because it's doing less work, but people never believe me. Just like you pointed out moving the air is the load. If your not moving any air there's no load.

[@davidholmgren659]

Great project with wonderful engineering. Well done...Dyson would be impressed.

[@meeester1418]

If I remember correctly, the material used in the latest Dyson impellors is a composite of PPS specialty polymer compounded with 30% or 40% glass fiber reinforcement. Plain resin isn't strong enough for the forces endured at extreme RPMs. Should make for exciting high speed explosions though.

[@mediumsmoke7823]

Cool to see! I actually did the exact same thing you did to the two motors. The only difference was that i wanted to design the "snail" so that the area inside of the snail does match the area that the motor outlet has from beginning to a certain point at any point around the motor. So the inner area of the snail rises parallel to the area of the outlet while you go "arround" the motor...if that makes any sense. I did this to have the same airpressure everywhere inside of the snail. I couldn´t finish it sadly. My CAD skills are still not good enough to make this happen :(

[@scottyp573]

This video was suggested by KZbin. It earned an instant sub after looking at some of your other video titles. Ingenious work!

[@friendlyfire01]

The dyson hair dryer doesnt only pull air from the duct, it uses the venturi effect to pull more air through another opening. that's where all your efficiency went!

[@friendlyfire01]

pweez twy it XD

[@jameshamaker9321]

for the next plane, remote controlled start, could work. also setting up the vacuum motors like jet engines could help with the stability, as well as ducting the intake could help with the thrust issues.

[@d4ro]

I think the backwards intake position was only working well because you designed the intake smoothly, so there will always be smooth airflow, but relative to flying the intake was causing turbulences which it immediately sucked in. one interesting thing is that suction force acts before explosion force, because the vacuum is dragging on the prop blade first acting on the molecules that stick to the surface of the blade, and mainly helps to overcome the inertia moment but its soon outruled by building up thrust (to which it is converted in a stream). I believe it is possible to harmonize and make a plane the works only by pull, however I dont know exactly how that would be, the thrust would have to feed its own intake instead of producing thrust

[@Squeaky_Ben]

Maybe you can make something akin to a jet engine: You set the impeller in the middle and let the exhaust of the impeller get redirected from all sides, basically creating a sort of bell shape that tapers off towards the end. Then you take a sort of trumped shaped inlet, so when the aircraft flies, it generates static pressure infront of the impeller, so it acts like a compressor. No idea about how aerodynamic that would be, but that is how I would do it, personally.

[@MazeFrame]

Was going to suggest the same. A setup like that could make for a more compact "thruster".

[@vincevanderperre8660]

Did you try even smaller nozzles to see if it increased thrust more?

[@agentduke2]

Brilliant idea for a project!! Well done. If you do a lot of 3D printing - which it seems you do :) - one trick for connecting FDM prints is to “glue” them together using the same plastic spool used to print them. There’s a dozen different ways to do this…but my favorite is to use a cheap $35 3D printer PEN, and feed a length of your spool through it. You can then just sand off any of the excess to give you a seamless connection that few would be able to tell was “glued together.” Keep it up!

[@terryboehler5752]

Love it. Nice experimenting, especially rotating the intakes

[@proph7543]

You could replace the snail flow-director with the same kind of flow director used in centrifugal-flow jet engines, which redirects the air all around the centrifugal flow and directly backwards.

[@kayzrx8]

then you could put a flame catch can and inject fuel and burn it for more thrust

[@davelowets]

That would only benefit an internal combustion engine. There is NO reason to bypass air if there's no combustion happening inside of it.

[@proph7543]

@@davelowets It's not a bypass, it's just a way of more evenly distributing the flow. See the following image for what. I mean. Ignore the combustion and turbine, just look at the compressor and how the air flows around it. en.wikipedia.org/wiki/Centrifugal_compressor#/media/File:Turbojet_operation-centrifugal_flow-en.svg

Small correction - the Dyson engineers did the engineering.

[@jimyeats]

Well, sure, they may have refined it, but James Dyson has a background in engineering and industrial design and spent about 15 years making his first bagless vacuum with cyclonic separation. So, I think it’s fair to give the guy a little credit, even if many of current components weren’t designed by him.

Id have a look at the Dyson hair driers if you can get them cheap, they're axial flow I think. Id also like to think 2 of those fan and motor units (compressors) mounted vertically staggered in a fuselage and a 60 degree swept wing would make a pretty fast aircraft... Like a tribute to the EE Lightning 😍

[@kain0m]

The problem with the hair driers is that they run on AC input. So they aren't as suitable for such an RC conversion...

[@rocketscience777999]

Woud love to see you use one inpeller to power a dyson bladeless fan which would probably provide a lot more thrust-to weight ratio. Jetoptera is actually using this technology to power the drones they are developing. Down the road you could rotate the dyson fans in fligt to take-off vertically and then fly horizontally.

[@mikevegeto1101]

Great video. Since the Dyson can create such a huge pressure differential, I'd be curious to see what a nozzle might do to increase thrust

[@davelowets]

What do you think he has on the end of it already?? 🤔 I'll be damned, it's a NOZZLE!! 😕

[@rafaelthetall]

it isn't that hard to ditch the snail shape for an axial shape and get a better aerodynamic profile. you could also check a multi-stage dyson turbine. it might increase both ejection velocity and flowrate. specially for a motorjet engine ;)

[@dustinbrueggemann1875]

Stacking identical compressors usually does nothing. You'd need the second one to be smaller so that there is a net confinement of the flow. The open air compressor can develop pressure because there is an unrestricted mass flow of air into it, but the second one can only work with the fixed volume that the first provides it. You might even see a decrease in net pressure if you stack them due to the back pressure on the first lowering its efficiency. You might see something happen if you use multiple parallel compressors to feed a single additional compressor, as that would create the net restriction needed to develop further pressure.

[@NonEuclideanTacoCannon]

@@dustinbrueggemann1875 You need a stator too. An axial compressor stage is, like, really freaking hard to build.

[@dustinbrueggemann1875]

@@NonEuclideanTacoCannon I don't think vortex effects are going to matter when there's already a manifold duct involved. Maybe some parallel baffles on the mouth of the second stage would do a little bit, but its not like the angular moment of the flow will be anywhere close to the speed of the impellers.

Technically the low pressure zone would still provide thrust as it is just Pressure * Area

[@marcusvinicios8129]

[@robinpollard7629]

The flared intake pulls air from all round. I guess you were hoping for the koanda effect to add lift/pull, but I think ram pressure overrides that. Replace flared intakes with a straight, sharp edged tube , so it pulls only from Infront. Ideally also fair the outside edges, but not so vital with the airodynamics of that beast. Possibly a stator to true up the intake would help, but not sure

[@neovo903]

You'd have to mess with the diameters of the tubing for the intake of the 2nd stage fan I think

[@neovo903]

Multi stage centrifugal pumps don't increase the flow rate but it does increase the total head. Since the thrust produced is from the flow rate then the thrust wouldn't be increased. You could try altering the diameter of the exhaust of the 2nd stage with a converging nozzle as the pressure would be higher to attempt to accelerate the air more to produce more thrust maybe.

[@annihil8ted993]
