For the tank tread propeller, you may be able to prevent the tips of the blades colliding by implementing a continuous curvature guide plate for the "treads" to ride on. Right now you are going from linear motion to rotary motion with no ramp up/down in speed, which is causing the blades to bunch up at the intersection where the treads overshoot coming off the drive sprocket.

For the caterpillar tred plane you could have just put the blades around a big circle. That way there would be less blades bumping into each other, and you would obtain a more constant thrust as well.

@joeventura1 4 месяца назад

Mom: Please stop making planes out of my blinds.

@Medievalfan94 5 месяцев назад

The collisions on the tank track prop blades was from the blades being violently taken from a circular to a linear motion. They wanted to go round and pitched forward while the next blade was already on the straight path forward and the tips collided. If you put some suppord rail under the tank track to avoid the track from bending in after the wheel it would reduce the problem and help with blade longevity :)

@Ericvl2102 5 месяцев назад

don't forget the pull on the " flexible " track. they don't move just in the axis of the track but they move but also move forwards and backwards. hence the massive loss in propulsion.

@jennareynolds1403 5 месяцев назад

I think the tank tread propellers have merit; just have them on a circular track. Then you essentially have a prop that rotates around a circle, rather than an axle. You could then have propellors wrapping around the hull!

@andreasvox8068 5 месяцев назад

Or at least an elliptical track. I think there's a problem when the blades come out of the turn and have to decelerate quickly, causing them to bump into each other.

@RyanWu_ 5 месяцев назад

There are so many better ways to achieve driven rotational motion around a hollow shaft. I hate when people online randomly claim that a mechanism would produce too much friction, but in this case I'll bite the bullet and say a tank tread would definitely cause too much friction for it to be worth any practical use, especially in flight where power efficiency is so important.

@tgregi 5 месяцев назад

But that was not point of that idea. If you rotate them in circle it will just look like nomal propeller round movement.... Wierdness of his plane was non circular movement)

@russbell6418 5 месяцев назад

Yeah, the opposite of the Stipa-Caproni! Not necessarily a good idea, but cool!

@AngryAlfonse 5 месяцев назад

I think the biggest barrier is the lack of guides. The belts were constantly bending inwards between the gears, as is natural for a high speed belt without extreme tension. You can see the belt bending inward and the props hitting eachother at the tips, even at fairly low speed. Just putting a block of wood between the gears for the belts to slide over would likely fix the problem. Hollow out said block and put bearings on both sides so the belt can slide across with less friction, if you want to make it well.

@IMacar 5 месяцев назад

@@AngryAlfonse I think the blade pitch is also an issue. Normal propellers 'twist' so that the forces all along the blade are even. The slower moving part near the hub takes a bigger bite of air, the faster moving part near the tip takes a smaller bite, but with the speed difference they're experiencing the same amount of force (on a good prop). With the tread system, to have the same even force all along the blade you'd need to somehow have every blade 'straight' on the flat portions and 'twisted' on the curved portions of the track.

@haassteambraker9959 5 месяцев назад

@@AngryAlfonse Yeah this was my thoughts too. Needs to be tensioned (there was some noticeable slack on a few of those before he turned them on), and guides if tensioning isn't possible/isn't doing enough.

@toddthecarver 3 месяца назад

I've always wanted to build a tank-tread paddle wheel drive for a watercraft. I imagine the blades dropping flat on the forward direction, then popping open when they enter the water.

Maybe even having the propeller go inside the wing during the corners to try and prevent excess thrust at the wing tips (assuming that matters).

the collisions between props and violent direction changes are what keep you from getting it to work properly, if you could use some sort of system, like return rollers or just guides, to keep it from pulling into the center via tangential momentum, you can prevent most of the propeller collisions, and most of your problems would be friction rather than propeller issues

I think the tank propeller can use some inner guides to dampen the violent inner turning on the edges as the blades seems to hit eachother a lot around where the round elements end. The stacked plane is simply amazing, do you think you can make one that has a fuelselage that looks like a sailed ship? I can totally see the stack acting like some eco-punk flying sail for something like that.

it seems more like an helicopter than a plane

The ship idea even seems plausible

@tomgray8156 5 месяцев назад

Yea, the tank propeller definitely needs runners or bogey wheels to keep the tracks straight between the wheels. Like you said, the blades kept contacting, and I’m certain that’s the main reason they kept failing and breaking. It’s a really funky concept; I think a quad engine plane with the tank propellers linking the two engines on each side would look awesome.

I agree the 20 stack was amazing. I didn't see the flight characteristics coming and they caught me off guard. I like it.

I love your channel man. Keep doing this stuff.

I think the main 2 issues you’re running into with the track props is 1. You have collision between your propellors, because your track isn’t guided enough. You could create a sort of moat on the inside of the track to guide it better. 2. Your propellors keep breaking off due to the centrifugal forces, you you might want to machine them in something stronger, like a light metal to make this work better, and machine them all in 1 piece with each tread link for less chance of parts just falling apart.

I wonder if printing them on their sides would help. I noticed the printing was done so the layers were not aligned with the direction of the force. This probably makes the surface smoother, but weaker

Love seeing old plane ideas tested and improved! So wild!

@lancebradshaw4829 4 месяца назад

Huh, funny coincidence. I independently thought up the tread prop a few weeks ago. Nice see how well it (doesn't) work. I figured it would have issues.

@HRZNEclipse 5 дней назад

Honestly, your main issue with the tank track propeller is the tension. You need a chain guide because at speed the chain is bending which made the propellers collide which made them break or the chain snap.

I love love love the multi-wing plane!! I really like the way it flies in the wind. Something about it gives very steampunk-machine-impracticality vibes. Please do it on a large scale, it would also be super cool if the fuselage was really tall with floors and floors of little boeing windows, or maybe even have several ones stacked!

12:44 when you add so many wings you become a helicopter

@victorjohnson2078 4 месяца назад

The multiwing plane was hilarious, I'm glad it flew as well as it did, very cool !

@philliprobinson7724 5 месяцев назад

Hi. The track propeller's blades when moving through the air will always exert a twisting thrust on the track, which will then de-track. Probably not a world beater, more like an egg beater. Great fun though. Cheers, P.R.

Heck yes, more airplane content! Thank you Peter Shripol!

@chancejohnson6575 5 месяцев назад

That multiple winged plane is a must do on a bigger scale! That was amazing to see it actually functioning like a helicopter basically but still crazy controller. Honestly maybe a rework of the design so it's not as wobbly on take off lol😂 but excellent job! Surpassed my hypothesis on it so I'd love to see more! I see this being a really fun one to fly around especially after a little rework of the design it's gonna be kinda next level!😂

@marasmusine 5 месяцев назад

That was really cool... it almost seemed to act like a VTOL! All those wings were a lot of drag, but the stall speed was really low.

@chancejohnson6575 5 месяцев назад

@@marasmusine right exactly thats why I'm kinda curious an excited to see them try to rework some of the design an get it's just a but more stable maybe even put a dummy on it that scales from about roughly 150 to 200 pounds person. Cause ot almost seemed to need something riding on it to help with the weight distribution

@tillowlglass1441 5 месяцев назад

I would (please) like to see you revisit the multiplane experiment but this time adding positive stagger to the wings ( setting the leading edge of each wing slightly forward of the leading edge of the wing below it) to see if it improved the flight

@christiankrueger8048 3 месяца назад

Thank you!

@StuffandThings_ 5 месяцев назад

I think that the blades on the tank track propellers keep falling off due to crashing into each other. On the straight portions only a small amount of give is needed to make them collide. A simple fix would be to just make them better spaced out. Though making it stronger works too. Either way its kind of a doomed concept from the start but fun to watch it work!

@TheBoojah 5 месяцев назад

Yep, or maybe give it a chain guide? Perhaps a slightly bent one so there is not a straight section but they whole thing is more like an ellipse.

@ianbelletti6241 5 месяцев назад

What I saw looked like too much flex in the track. Some guide and tensioner wheels should help with that issue.

@jclark2752 5 месяцев назад

I always wondered if multiple wings would allow slower speeds in a shorter wingspan. Awesome to see it up and flying! I am Stunned! 🤓

@russbell6418 5 месяцев назад

You need considerable space between wings to get efficient lift. Too much turbulence. One quadriplane in WWI, but triplanes seemed to be the reasonable limit. Some special use biplanes still exist. Check out Staggerwing and Griffon Lionheart for true beauty.

@douglasthecorgi2568 5 месяцев назад

The Sopwith Triplane was designed to overcome the poor visibility of its predecessor, the Sopwith Pup, by reducing the chord (front to back dimensions) of the wings while maintaining the same lift, and it worked out. I believe the same would hold true for wingspan. You’d get less efficient gliding, but faster roll rate. IIRC, the minimum space between wings for efficient lift is the same as the chord (measurement from front to back) of the wings (or, if the wings you’re spacing don’t have the same chord, then the spacing is the average of the two chords). Also, IIRC, staggering the wings lowers the required spacing distance; not sure what the formula for that was, though.
