I think you should focus more on the rim design, so it doesn’t have the deflection when it’s spinning. If you can keep the rim true the tire have a lot more lifespan, whether it be a solid strip of rubber glued on or hard foam.

@adamneff1600 Год назад

i noticed this as well, i don't know how nobody has seen that. The inside part of the rim where there is no support is causing the ballooning, you can take your hand and squeeze the wheel they are so flimsy. Need a stronger rim, metal, carbon, just thicker, or some kind of support there.

@skullbones7452 Год назад

I agree, the foam gets ripped off because the rim expands uneven.the weight of the car will reduce this but not enough to prevent it.those rims are key to keeping the rubber side down; :) i would suggest a wheel out of steel;Dont use aluminium because my teacher in school told me that aluminium is actually heavier then steel because its much weaker.They say its better because it looks better But a steel rim is actually better then a aluminium one.

@jeffgTrialsBikes Год назад

Almost for sure the inside is expanding more then the outside!

@jeffgTrialsBikes Год назад

absolutely, maybe an inner ring to support it!

@Davivd2 Год назад

Exactly. The rims will be the point of failure. I'm surprised that he's not using aluminum.

@chriswheatley123 Год назад

We have a carbon filament winding machine at work, usually used for winding high speed rotors that run at well over 100k rpm. You need a carbon sleeve that presses on over the wheel under interference. The hoop stress will resist that expansion you are seeing, then possibly bond the tyre onto the sleeve.

@marcopruscini1603 Год назад

Seems to be a good solution and on the top, the compound of cfk and genuine wheel material reduces vibrations on the rim what results in less stress too.👍

@martincollins6071 Год назад

That's sounds legit to me, i love these comments. I also like smarts and problem solving

@likzen8876 Год назад

nah at that rpm only good for drifting, no speed run

@anthonyrawsthorne656 Год назад

Think Castle use a Kevar band in their motors? Not sure if going for a GRP/kevlar weave wheel, but adding a grip element (ie weave a rubber element into it ,in the manufacture process) , so the tyre is a structural part of the wheel, not 'just' stuck on after?

@wilsonsantiago3095 10 месяцев назад

Call me crazy I would use aluminum or carbon fiber rims

@dantechunknown3760 Год назад

I was just thinking and came up with a idea. It seems to me that the foam isn't the problem because look how always the inner rim expands. Try cutting 1mm inner side foam and put a fiber or metal ring around it so it doesn't expand.

@kenvanpassen9247 Год назад

This is the answer that will help Kev brake the record!! It's genious in its simplicity. This needs to get upvoted hard!! Those banana's held up to nearly 50k rpm... it wasn't the foam detaching, it was the inside of the wheel failing. Strengthen that, and you've got your world record contending wheels. Kudos! :)

@bmxstar14 Год назад

I was thinking either this, or a wheel that has even a little support on the inside when it’s designed. Basically what you’re saying but on the inside

@amirxr8464 Год назад

This test was not in load mode. And because of the high rpm, the rims became like that, and when it is installed on the car, the main problem is the foams. Because this car is very heavy

@bmxstar14 Год назад

@@amirxr8464 the same effect still happens just not as much. 100% worth trying over just assuming it’s cause it’s “under load”

@coreytaggart128 Год назад

Would be hard to put on. My first thought was something like a piston O-ring but that has a notch in it to allow it to expand and that is what we are trying to prevent. Would almost need to bend the wheel in to make it fit that way it isn't larger then the wheel and can't open up. overall though the thinner the wheel the easier this will be to do as there is less lip to worry about expanding out, however it does mean less traction to get up to speed. so you would become more limited by max run distance.

@davidskala7652 Год назад

The amount of power you have to have to not only strip the inner wheel while still completely blowing the outer diameter off of the rim is absolutely insane 😅 this thing is a rocket! Keep up the great work brother much respect!

@chebarcebal1068 Год назад

tata1293

@bastik105 Год назад

But maybe that´s also Part of the Problem. When the Car gets a little lifted, the Wheels will instantly gain a lot of speed and reach the critical Point of the Foam. Connecting it to be a 4*4 like Kevin, planed should really help. To sum it up he could maybe try to set a max. RPM for the Motors to reach, depending on what Tire he is using? Really dont know if its possible, but it would make sense to me.

@st33ldi9ital Год назад

Once again... Get you some aluminum wheels. Drill some holes around them on the inner rim. Dip them in a rubber epoxy compound. The holes will allow the compound to bleed through to both sides and provide support while preventing ballooning. Let them run off and dry sideways for easy clean up and balancing. All you need is the right rubber epoxy compound...

@gabrielbanta5098 Год назад

That is actually really smart man, I hope he tries this

@MurderSTi Год назад

This, but make the wheels out of carbon fiber over aluminum.

@taco42O Год назад

@Davivd2 Год назад

I'm so excited for Kevin. He's put so much work into this. I hope that it at least makes a full potential pass without mechanical failure.

@NovemberFoxtrotRC Год назад

Not sure if he mentions it later in the video but on the first dyno run the wheel itself under the foam tire is expanding as well. Maybe a wheel with stronger material and or more cross bracing inside would help keep the tire together longer.

@CroftyOriginal Год назад

Tip: Left handed drill bits are really good for rounded off screws. Instead of just drilling them out, 9 times out of 10 they grip and just thread the screw out.

Tires are critical for electric-motor cars, because they have to carry all the power. But crucially, Project Air's jet-powered car puts power directly into the air... its tyres are just for rolling and steering. So this is vital to crack for the motorcars to win

@jordantobins681 Год назад

I think you should really consider larger wheels and then go with either foam or rubber. The larger diameter wheel won’t have as many rpm’s at speed, and you will deal with a lot less centrifugal force. Just build a body with big, smooth wheel arches, and mold them smooth. Sort of like the Batmobile. If you run a wheel that is 5” vs running a 2.5” wheel, it will have to spin 1/4 the speed as a 2.5” tire to cover the same distance in the same time.

@robinclaidlaw Год назад

Half the speed not quarter, circumference varies linearly with diameter, but yes, bigger wheels will help.

@captainchaos3053 Год назад

Well yes and no because much like a cutting bit the speed on the surface is linear. A reduction in weight/density might help but ultimately it's the tensile strength of the rubber that is the problem. I would suggest using a urathane wheel which can have a certain amount of deflection under load but is much stronger than rubber or foam.

Tip for getting small bolts and screws out without stripping - Take your driver, and a hammer, put the driver into the bolt and hit the top of it with a hammer for a few sharp shocks. This usually "breaks the seal" and makes them much easier to turn without stripping

@sleepyforest3359 Год назад

@simon333ork Год назад

Have you considered modifying some skateboard wheels to fit? I guess you could mill out the centre’s to fit hubs inside, there’s a massive range of “A” hardness ratings to suit the grip you need plus I’m guessing the extra weight might help with stability? Just a thought?

@RobAuditori Год назад

Curious about fire sprinkler system. I've been a designer of fire sprinklers for years. i was intrigued when you mentioned your system. is that a compulsory system? or did you install, or have it installed ?

@techienate Год назад

Use larger diameter wheels! Larger diameter wheels will have lower centrifugal force. One way to visualize this is that larger diameter wheels rotate fewer times to achieve the same velocity of the car. Lower RPM=less centrifugal force. As an engineering student, I'll design you a wheel if you're interested and if you will pay the material and machining costs! We could make a carbon fiber or aluminum wheel, balance it, and attach foam for traction.

@CristiNeagu Год назад

My question is: Why don't you use bigger tires? The bigger the tire, the lower the rpm for any given speed. Also, you forgot to blur a frame with the wheel when you were balancing it, so... I think I know what you're doing.

Can't wait to see it go down a proper drag strip!!!! Much smoother and way stickier! Have some of the track adhesive on hand to help out with grip... I wonder if wheel slip is contributing to tire destruction? The tires are putting a lot of power down, and they must be slipping and getting damaged, especially as wind resistance increases. 👍 hell yea!

@cyclemadkiwi Год назад

As below, a nice set of CNC machined Ali (7075 grade) rims (couple sets to change out) and get them into a mold to skin them with PU! a good 95shore Polyurethane molded onto the Ali rims will make this thing really haul ass! Coming from a background in racing control line planes over tarmac (Barkston Heath Airfield being one spot!) we use a hard tooling grade (Red) Polyurethane for the tire and it takes a beating. Just an idea

@eukaryon Год назад

No worries about stealing that design. The rim deforms so much, the vehicle will become uncontrollable. A cross section shows an L, a problem shape that change of material will not overcome. It needs at least a T cross section similar to ordinary car wheels. Excellent idea to do bench testing before taking it out. More testing!

@MrLarsgren Год назад

seeing how the foam reacted i got a crazy idea that might work. make a alu wheel with holes in it and place the foam on the inside. should keep it from exploding . just need a really thin foam on outside to get it moving then at speed the foam or rubber on inside will be slowly pushed trough the holes . gonna act kinda like a water balloon on a tennis racket.

@darrenconway8117 7 месяцев назад

After sorting out the wheels/tyres, I suggest focusing on vehicle aerodynamics to increase speed. This would make a great project for a university student as part of their Masters/Doctorate. If you can make the car/body narrower, lower, and with less drag. Reducing drag is free speed. Railway train wheels have steel tyres under high tension, so the suggestions for carbon fibre sleeves make sense. Consider replacing the carbon fibre chassis with 6mm honey comb core between carbon fibre. Much more rigid but not so robust. Chinese sources will CNC cut it to your drawing. If you are using stainless steel or titanium screws, or steel screws into aluminium threads, lube the threads to stop galling (makes the screws impossible to remove).

@thomasfeix7979 Год назад

One thing to not forget is that the wheels also need to transmit a lot of tangential force (basically the force that pushes the car forward). You an estimate the force (for all 4 wheels together) by P = F*v (power = force * velocity). You know the power from the motors and how fast the car is going. That gets you the lateral force the wheel needs to withstand. For this reason I think the project air jet turbine car will not be as limited by the wheels as they don't need to resist the lateral force. Only centrifugal.

@Jokerman1215 Год назад

I think the wheels need support further out on the barrel. They're all on the face and that's causing it to balloon. Maybe the stretching and twisting of the wheel itself is causing the glue to heat up (because of the expansion) and unstick?

@pederbowers7700 Год назад

@AlexGFrank Год назад

So here's my logical conclusion on the wheels IMO the best possible idea will be to machine them out of something like Mg/Alu or Ti/Alu alloy with lots of internal supposrt, and grue a thin strip of silicone on top for the grip. Not foam, not rubber, silicone. Yes, it's probably going to expand a bit more, but it's way more heat-resistant, and it theoretically should be more resistant to rubbing on the asphalt. Plus it should give an insane amount of grip, if threaded correctly (look at semi-slicks on the hypercars for reference)
