You could vary the run times of each rubber band to create a sort of staging for each motor. For example, if the central motors had a duration of a few seconds, they would dump a lot of energy at the start, from which the plane could then coast, running off lower output from the other (longer duration) motors. Kind of like how rollercoasters often add all their energy in one go at the start of the ride! Excellent video as always!

But he said it didn't have enough power to climb with all engines running (so only just flying really) and props not running are a massive drag and dead weight. Longer rubber motors are the way to get longer flights and maybe over winding...

gives me an idea, what if he could vary the stretch lengths with a servo, maybe that could be a simple way to have some control over thrust without too much loss due to friction. or even better, use another elastic band to keep tension on the twisted one while it is unwinding!

As a 77 year old I well remember rubber powered planes, I also remember my dad telling me about lubricating the rubber with BANANA OIL ! yes there is or at least was such a thing. I tried it and it as I remember worked really well. I suppose it lowers the internal friction between the bands.

Glycerine is best. It reduces the friction between the strands of rubber allowing them to slide over each other. You’ll get more winds on too. Keeping the rubber cool will give better performance also. Leaving it in the sun to get warm reduces its performance.

If you really want to get into the weeds of rubber power, have a look at what some of the indoor free-flight people are doing. Not everything they do would carry over, but a couple things from when I built rubber planes in high school: - lubricating your rubber bands somehow is important, find something that doesn't damage the rubber though. It lets you wind it up much more before they start breaking. - pre-stretch your rubber bands: I would always cut them to ~1.5 times the length of the mounting points, and then before I start winding, pull the rubber bands back until they're stretched to ~3x their unstretched length. This lets you get a lot more winds/flight time, at some reduction in instantaneous power. Really excited to see you continue working on this project! best of luck

The elastics could be wrapped around a small drum on, or via a simple gear reduction to, the prop shafts and anchored to a point somewhere beside the drum. Fairly lightweight and directly translates the linear stretch into rotational motion. I think this would be neat because a person can vary the tension that gets wound onto the drum with each turn, too!

This reminded me of The Great Egg Race (BBC Two TV show in the 1980s). The original challenge was to make a wheeled contraption powered by a standard rubber band to transport a hens egg as far as possible. From memory, the key to great distances was using a fusee to even-out the release of energy from the rubber band.

Mechanically, this is because the exert a bigger force when tightly wound, compared to later when they are partly unwound. The fusee is like a kind of continuously variable gearing that slows down the release of energy at the start, and then make the release of energy easier (through mechanical advantage) later on.

Had a random thought about rubber band planes. Could you try attaching a band to an adjustable rail or screw shaft, geared up to the rotation of the prop and use the rotation to stretch the band as it unwinds? The purpose of this would be to increase the efficiently at which the planes uses the stored energy, perhaps extracting a little more than it otherwise would and maybe increasing the time a loft.

@sperzieb00n Жыл бұрын

a much lighter way to do that would be to use a second elastic band set up to just provide linear tension, or even an alternative setup of the rubber band, where the loop forms a triangle with one point on the prop and 2 on the body, so winding also makes use of linear tension.

Drag from the stationary props could become a problem don't you think? Longer elastics would help, but the ways he runs them currently, he would have to add longer spars, which adds more weight. I wonder how much a tiny 90° bevel gear at each prop would weigh? It would let him run a much longer elastic under the wing, and if it's a torque reduction, he could beef them up as well, and get longer runtime that way too.

Yes, you have to balance it with the kind of rubber you have, though. Thickness/linear density, length, and quality all play a big roll. The condition's this rubber were being subjected to were not the best, no o-ring, no lubrication, and poor weather.

The first model airplane I ever built that actually flew (and amazingly, I might add) was a very primitive kit for a rubber powered parlour plane (or penny plane) when I was about 13 years old. The kit was very crude. I had to not only cut the wing spars from a solid block of balsa, but then cut the airfoil into them. I had to fashion the propeller out of thin balsa stock using an aluminum can as a form for the contour. The covering material wasn't tissue, but more closely resembled the skin you get in the pan after you boil pasta. When it was all finished, it weighed just a few grams. It was an indoor - only plane, obviously. It flew fantastically! Probably at less than 15' per minute, and the torque from the prop shook the whole airframe as it crept along. A sneeze would have destroyed it.

For FF gliders, it's always best to have a bit fwd COG and some decolage, cos you can't correct for gust stalls. Too much will lead to oscillations but too little will give you squirrely pitch.

I’m a rubber powered freeflight guy, and this is pretty interesting. First though, you’re leaving tons of rubber performance on the table. It appears you are using 1/4” tanII super sport (the good stuff), so from the turns per inch of loop table we get 69, and assuming your loop length is 18” that’s a maximum of over 1200 turns per motor. The torque skyrockets as you near max turns but even winding to 80% you should be safe at around 1000 turns per motor, more than 3x what you said you were using. You might consider fewer motors and bigger props, but the winder you are using won’t handle a cross section much more than you have.

For the 30-second challenge, couldn't you servo operate a 2nd batch of props to increase flight time or is that not allowed for the GB of Records? In fact do they even allow electronics at all?

this is definitely not the largest plane because in our aircraft modelling club back in 90's we had standard schematics for rubberband planes of approximately that size. the trick to storing more energy is definitely not using more rubberband engines, it's using much longer and much thicker rubberband threads. we used to have a glass fiber pole as a frame with length of about 2m and about 0.5cm^2 rubberband. another important thing is to make the prop foldable (backwards) so that once the plane reaches its height it folds and does not produce extra resistance. the engine works for about half a minute and its glide time depends on your skill and where you launch it, but it's on the magnitude of minutes.

@HobiCerdas Жыл бұрын

I love going back to the basics occasionally, I wonder if instead of having a rubber band on each prop, you could tie all of the props together with a light pulley system and put all the rubber bands together down the center of the frame and drive all props at the same rate and you would only need to release one spot to get all of the units spinning, you would have more power available and with some small gearing you might get quite a long flight time.
