Hey a tip for your air storage: people that build water rockets have perfected splicing plastic bottles together for high pressure use. The channel US Water Rockets has some good videos about bottle splicing. You could save some weight and make larger chambers fairly easily.

That sounds like a good idea if it can take the pressure. There's a lot of weight in the bottom of the bottles and fasteners. Also, here in the US we have 3-liter soda bottles. Fuse a couple of those together and you've got 50% more capacity in probably less weight.

Hi, something about your wings. Wings have the most drag at the ends because there the pressure between top and bottom is balanced and you get a whirl. For that reason the wings of a sailplane are long and get narrower to the ends. In your design there is a problem in the center too because the wings aren't connected and you loose pressure in the middle too. I think, it will already help if you connect the wings with some packaging tape. Best regards, Frank

Hi Tom, epic project! I'm sure you've had lots of suggestions but I'll throw in mine anyway: 1. Replace the MG90S servos with standard SG90 servos, you don't need metal gears and this will save about 4g. You could also go smaller (GH-S37D) for a total saving of 15g and reduced size of the supporting structure. 2. Smaller LiPo pack. 3. Build up the tail surfaces from 3mm square balsa rather than sheet. 4. Taper the wings - better lift distribution and structural efficiency. Taper the spars to reflect the reduced bending moment as you move towards the tips. For tubular carbon you could glue increasingly smaller sections together, telescope style. You may need to add a few degrees of washout at the tips but this is easily done by twisting the wing to the desired angle and re-shrinking the film. 5. Lose the gap in the wing centre section and make the wing continuous. This is a big source of drag and is effectively halving your aspect ratio. 6. Add some rounded or tapered wing tips 7. Test some different props to find an optimum for this engine / airframe combination. This can make a big difference. 8. Higher pressure of course. 9. Don't use paint, it's heavier than you'd think and not needed under the film. 10. Use an iron rather than a heat gun to shrink the film. You'll have much better control and won't melt holes in it. On your comparison to CO2 canisters, I'm not sure that's valid as the CO2 is compressed to liquid phase so it's not just a comparison of ideal gas volumes. Great work though, I look forward to the next iteration.

I'm thinking tapering the wings may not help here. This plane flies super slowly, and is probably nearing the unfavourable range of Reynolds numbers, where the air starts becoming really sticky, and shortening the wing chord would exacerbate that. Perhaps adding a turbulator would help, you can try that on one wing first, which will let you easily gauge if it's improving performance (if it does, the plane will have a tendency to turn to the side with no turbulator).

CO2 transitioning a phase would make it way worse by cooling it down significantly, so if Tom's calculation is incorrect - it is incorrect in favor of air, not CO2. Also, Tom, please make a prop saver - a small modification that fastens the prop with a small rubber band instead of screws. You will easily find it on the internets by googling "propsaver"

@samuelmellars7855

With regards to the CO2 cartridges: A quick google says a 12 gram cartride (12 grams CO2, not considering weight of cartidge, I assume) has about 6L of CO2 at atmospheric pressure. I think it might not be worth it. It's slightly more weight, it's a part that has to be purchased *and* more strength needs to be added to the design to hold the higher pressure. Unless a larger CO2 bottle can be got easily and cheaply. Better CO2/bottle weight ratio. Thinking about the rest of the design: I think I would add a sleeve around the join of the two tanks to reduce drag. Could also have two double-tanks side-by-side (4 total), have any less aerodynamic components between them and wrap the whole thing in the film. Add a few shapers and make it into a lifting body fuselage, while we're at it.

Two tips. 1) I have been recycling PET diet coke bottles into printer filament for some time. My first step is to smooth out the iconic shape by pressurizing it to 70psi with a little water and heating it slowly in an oven. I've successfully shrunk, elongated in a form, and reformed the bottoms into a smooth dome. You may want to consider doing the same, giving you more volume at the same weight. Coca Cola published that their 2 liter bottles are rated for 150 psi, so if you only need 70 some experimentation might be warranted. I would love to see what you come up with. 2) Secondly, you could replace the tail rod with a pressurized fluorescent tube protector and make the plane a flying air tank. The water rocket people use them as pressure tanks as well, so there is a lot of data and technique to start with!

For instance, if you get the threads of the bottle too hot the deform. Not a good thing if the bottle is at 70psi. The PET recycled filament people put a small amount of water in to use steam to expand the bottle if they don't have access to a compressor.

Do not use paint, it adds about as much weight as your balsa! Instead buy colored Oracover. It has same weight as clear! Also: Look into using a folding propeller to avoid damage during landing. I am assuming power is low enough to let it fold on landing or that at least the blades will fold away upon hitting ground to avoid the snapping of motor. The rpm of motor sounds like it speeds up as the plane reaches level flight which could mean pitch is too low. It shouldn't take much thrust to keep such a sleek wing in the air, and too low load on motor in flight will just use up air.

I just wrote the same as well. And there are also 20g, 38g, 45g, 74g cartridges that will have much better ratio of the useful CO2 weight to the metal canister weight. And you're getting much more constant pressure, compared to that air bottle that drops from 8 atm to 1 atm. There are problems with CO2 as well though - it will need a strong/heavy valve and you have to maintain the cartridge orientation, so you're not directly losing liquid through the valve.

Use an electric air compressor with a WATER SEPERATOR on the line going into the Plane tank. less water in the air will reduce the weight at the end of the flight and will make your air engine run ever so slightly better.

Great video as always! Here's a tip to decrease the drag and increase the lift. At the moment you have two half wings joined together at the fuselage. This design generates some vortices (exactly like the wingtip vortices) in the inner part of the wing due to the gap between the two half wings. The vortices increase the drag and decrease the lift. Joining the wing in the middle would eliminate the vortices

Tom, I'm sure someone else has mentioned this before - but the CO2 canister is not actually full of gas. It's full of liquified CO2, held under that pressure.

Build a wing of linked bottles? - sized to form the aerofoil? - "We'll need a bigger pump!" : )

This has been such a fascinating and well made series. Multi-engine plane soon?

this is f^cking sick dude, not only do you have all the engineering down, but you understand all of the aerodynamics and piloting details too, very impressed

This is crazy. Absolutely astounding progress.

Hi Tom ! I was following your updates for a while. As an Air Hogs lover, I got into your journey to build your own air powered plane. Just let me say that I'm really proud of you !! 1.22 minutes is more than a sucsess !! it is MARVELOUS !! UNBELIBABLE !!! BRILLIANT !!! Your determination and your amzing skills are really impresive !!! Congratulations from Buenos Aires, Argentina !! And of course I'll be tuned to see the next flight !! Many thanks Tom !! YOU DID IT 💪💪💪!!! Hugs dude !!

If this doesn't become a kit you can buy I'll be so upset! Amazing work Tom as always!!

As a lowly software developer this is absolutely brilliant content. Happy to have youtube recommend this channel to me.

Congrats! Very well done. This has been like going back in time and watching the Wright Bros at work. 😄

I'm so impressed by the level you reached after all those years, it's so satisfying to watch the evolution of your designs ! Keep going mate ! 💪

Just echoing everyone else: it feels I've been watching you build these since forever ago and it's amazing to see how far you've brought it. Superb work.

That engine screams and is really powerful. Super impressive!

I absolutely loved that, thanks for sharing.

Duuudeee, now imagine letting these parts produce as a universal kit for all the usual bottles out there and then .. kitefests and GIGANTIC AIRSHIPS MADE OF BOTTLES, PLEAZE!!

I was thinking the same thing. Maybe there is some lightweight tubing that he could route through the holes... as long as it could hold pressure.

You probably need as round a shape as possible to maximize volume per unit surface area, since the surface needs to be strong and therefore heavy

I‘m guessing high pressure air tanks will make this unnecessarily complicated or would require molds and industrial equipment only a mass product could make cost efficient use of.

9:46 lol Bad batch of balsa wood. I love watching your projects come to life. You inspire me.

Such a great project. Well done.

Great evolution, Tom. A few suggestions to add to what other people already said: 1 - splice multiple bottles together for added air volume while shaving some weight. 2 - As you add more bottles, you might want to consider using the bottles as a structural piece to hold the tail. It will save a bit in terms of size of the aircraft and might end up saving some weight too. 3 - For the balsa wood parts, you can probably make some more holes into it without affecting the structure too much. And since we are talking about shaving some grams, you might want check the weight the paint is adding. Looking forward to the next video of the series. =)

Valid points

One potential improvement I can think of is recycling some of the air from the expansion stroke of the motor to give the return stroke a small boost. It might even smooth out the impulse and lead to less rattling.

I was thinking this will cause the piston to move back up above the exhaust hole before the pressure has dropped enough for the seal to retract. But then I realized the seal responds to differential pressure... So if anything you'd want to create a chamber below the piston where you dump gas to hasten pressure equalization which will break the seal, and then expediate the exhaust extraction, without actually introducing pumping losses on the powerstroke. I think overall you'll have more benefits from larger exhaust port area, and maybe you can harness some efficiency by nozzling the gas backwards for direct propulsion, or directing it at the crankshaft to accelerate it through bottom dead center. But then you're going to have to consult Alex from 2stroke stuffing about how to tune exhaust pulses I think 😅

@thegregdavieschannel

I was also thinking along these lines. If the high pressure air was applied to the underside of the piston where the surface area was a little less and then using the spent air on the conventional side of the piston it could help balance the pressure losses.

@VyantQuijt

7 ай бұрын

@@thegregdavieschannel but if you're injecting pressurized air on the crank side you have a larger volume to fill and will probably have airleaks around the crankshaft or need seals to minimize losses. I think both will likely hurt the overall efficiency more than you'll be able to harness with recycled gas

@@VyantQuijt some steam engines used a larger secondary compounding cylinder to harness some of the residual energy. It would be really neat to try and make that work in a single cylinder engine, but alternatively a twin cylinder engine might be the way forward.

Duuuuuude this is so fricking coool! Congratulations! All those years of hard work have paid off!

That is great video. It is very interesting to watch the whole process of engineering such complicated thing

This may be a crazy idea, but what if you had two bottle fuselages each with their own engine? kinda like a P38. Or maybe you could get four bottles together and fly it with the twin cylinder engines, which while less efficient should let you climb better and then you could glide for longer. Also the increased weight would make it handle wind better.

Yes, now that we have done the efficient stuff, lets have some fun and do some ridiculous stuff.

If the tail feathers were stick-built like a typical (now considered old-school I suppose) balsa model, it would be lighter than a slab of balsa with lightening holes drilled in it. Love watching you develop this project, Tom!

@hisokaf6793

7 ай бұрын

My thoughts exactly. Same with the wings, and no need for the leaving edge sheeting at this type of plane. Nothing beats stick balsa when it comes to stiffness to weight ratio, maybe carbon fiber but not by much.

This is incredible, i love everything about this

I've loved this series. Thanks Tom S.

I've literally just paused at you pumping up the bottles "for the first time" I love your attention to detail and how much you cover each iteration. This feels like the culmination of a real journey. Hope it goes miles Excellent work.

YAY!!

I have always thought that those 12 g CO2 capsules have 12 g of liquid CO2. In that case one 12 g CO2 capsule would have something like 6-7 liters of gas depending of air temperature and pressure.

@leocurious9919

You were thinking correct. He, for some reason, assumes it is just pressurized CO2 gas. At which would they could just as well have used air. The whole point of CO2 is that it is a liquid.

This is insanely impressive. Well done

Great Work on this Project!!

So glad to see the accumulation of your research unfold into this marvelous flying machine! Great work!

This is fantastic! As a fellow AirHogs-era kid, I'm so happy to see you succeed to such an amazing degree! Next up: 5 minutes!

You continue to inspire me with every video! Not even my discipline of engineering but there's just something so satisfying.

everything about this is awesome but what stands out to me is how satisfying it sounds 😩😩😩😩

LETS GO TOM ive followed this series for years and always excited the moment i see a video. i’ve been following the engine series and knew something big was coming for some time great work again

Watching you slowly improve your engine design has been the most interesting part to me.

This is honestly super impressive. Well done. Wow....

That's why pilots have such extensive pre-flight check lists.

Watching you tackle each issue that comes up and continuing to improving it at the same time so satisfying. The finished product looks so cool and seeing it successfully fly for that long was impressive.

Imagine if Tom Stanton, Integza, and Peter Sripol all got together to build an airplane...

Thanks Tom, I appreciate your thoughtfulness and delivery :)

Its feeling really good to see the development on this project. From one video to another you worked really really hard and finally made it. Congrats man.

Not only is this plane amazing, but it looks extremely cool. The fact that that is because of design requirements, and not aesthetic reasons makes it even better. Amazing video as always!

This is a great channel, so inventive. Keep up the good work Tom !

Brilliant! A friend of mine flies RC gliders, he uses surgical tubing and sting to launch the gliders. He uses natural thermal up drafts to lift the gliders to extend the flight times.

I love it. It has been super cool to see this project unfold one KZread video at a time.

Congratulations!! This is the culmination of a multi year journey. I'm so glad you brought (and continue to bring) us along for each step of the adventure!

brilliant execution. that second flight must have been a huge rush!

watching you develop this over the years has been amazing. Proud of what you have achived!! Amazing finly tuned engine and an awsome plane body/wings!
