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 9 месяцев 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 9 месяцев 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 9 месяцев назад

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

@jeffgTrialsBikes 9 месяцев назад

absolutely, maybe an inner ring to support it!

@Davivd2 9 месяцев назад

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

@chriswheatley123 9 месяцев 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 9 месяцев 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 9 месяцев назад

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

@likzen8876 9 месяцев назад

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

@anthonyrawsthorne656 9 месяцев 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 6 месяцев назад

Call me crazy I would use aluminum or carbon fiber rims

@dantechunknown3760 9 месяцев 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 9 месяцев 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 9 месяцев 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 9 месяцев 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 9 месяцев 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 9 месяцев 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.

@Davivd2 9 месяцев 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.

@st33ldi9ital 9 месяцев 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 9 месяцев назад

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

@MurderSTi 9 месяцев назад

@davidskala7652 9 месяцев 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 9 месяцев назад

tata1293

@bastik105 9 месяцев 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.

@ashsingh9339 9 месяцев назад

@NovemberFoxtrotRC 9 месяцев 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.

@Alexand3ry 9 месяцев назад

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

@R33-GTR 9 месяцев назад

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

@simon333ork 9 месяцев 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?

@jordantobins681 9 месяцев 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 9 месяцев назад

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

@captainchaos3053 9 месяцев 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.

@audiquattrojamie 9 месяцев 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 ?

@CristiNeagu 9 месяцев 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.

@volvo09 9 месяцев назад

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!

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

@thomasfeix7979 9 месяцев 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.
