3D printed atmosphere powered boat
มุมมอง 357K2 ปีที่แล้ว
This is my design of an atmosphere powered (or vacuum powered) boat. It's far from perfect, and there are plenty of things I could do to improve it (make sure the propeller is actually fully submerged, use a draft tube, dual prop, etc), but I just wanted to get this video out since I haven't posted in so long! Still, please do give any ideas for improvements or future videos in the comments! I ...
3D Printed Opposed Piston Engine - How powerful is it?
มุมมอง 13K2 ปีที่แล้ว
In my last video, I designed a 3D printed Opposed Piston Engine. I wasn't too sure what to do with this (or any of my other engines), so I asked for some help in the comments. One of you suggested trying to lift something, so I tried to lift a banana. DISCLAIMER - 1 Banana was harmed in the making of this video

Compressed Air Piston Engine V3 (3D Printed)
มุมมอง 18K3 ปีที่แล้ว
This is my 3rd attempt at making a compressed air engine. This time I've implemented a sort-of exhaust valve, improved the strength of the engine and increased the running duration! There's still more I need to do to improve this engine, I still don't think that it is strong enough, so I may use PETG for some of the parts next time to see if this helps. Also it would probably be good to see the...
3D Printed Air Engine (V2.5)
มุมมอง 4.1K3 ปีที่แล้ว
In the comments of my last video, a lot of people had suggestions on ways to improve the engine, I couldn't do them all in one video, but I've looked at a few here to see if they will help. The first was using a ball bearing instead of a BB ball for the valve, this definitely reduced the amount of air leaking from the valve so was a great suggestion. The next suggestion involved using a square ...
3D Printed Air Engine V2 - Upgrades
มุมมอง 12K3 ปีที่แล้ว
In my last video, I showed the development of my version 2 engine. In this video, I've tried to make a few improvements such as designing a flywheel (rather than using a desk fan blade) and reverting back to a BB ball to reduce the amount of air that leaked through the valve. This version was a huge improvement, at least in terms of engine speed, compared to the previous engine which had a peak...
3D Printed Compressed Air Engine V2
มุมมอง 15K3 ปีที่แล้ว
In this video I show the development of my version 2 compressed air engine. The majority of the parts are 3D printed on my Ender 3, with some other easy to get parts such as nuts and bolts, O-rings and metal bearings. The previous engine had a run time of about 15 - 20 seconds when starting at 60PSI. The first iteration of version 2 lasted about 4 seconds and then fizzled out pitifully. I then ...

    Why use an extra piston, you are doubling the piston ring sealing surface and area! the "opposed" thing is ok, I guess, but if you hooked the cylinder to a crankshaft it would eliminate the second piston.

    Hi Kurzey, question here, I am also making a compressed air opposed piston engine here, but with a valve similar to those used on a 4 stroke engine, I know it brave as I could find very few compressed air engines with valves which aren't ball bearings, but i notice you have printed your cylinder as one piece with the valve assembly, how did you get the support out, and if you didnt use support, which orientation did you print it? And lastly, what is the clerence of the pistons in your cylinder and did you sand them at all? thx so much in advance

  • @gadgetdeez7069
    @gadgetdeez7069 3 หลายเดือนก่อน

    Even your revised model shows a shitty cam profile. The air valve in this case needs to be cracking open the second it hits TDC. This isn't an internal combustion engine that needs a lead time to burn fuel and develop pressure so there's no sense in opening the valve prior to TDC as this will only fight the rotation of the crank. The air valve should also be CLOSED by the time the exhaust ports are opening. which in your model it closes AFTER.. This will have DRASTIC impact on run time and efficiency, as the "Blowdown" cycle never happens which means your crank is fighting residual pressure coming from BDC x2. If you REALLY want to make power, you need another valve for exhaust and eliminate the cylinder ports. As the pistons are headed toward TDC, the air valve is closed and so are the exhaust ports. There's literally NOWHERE for the trapped air to go. This SLOWS DOWN the crank and wastes significant amounts of power.. With a dedicated exhaust valve in the same port as the intake, you can 100% control air flow in the engine and eliminate any pressure buildup prior to the next intake/power cycle which will extract the most amount of power possible. I'd imagine a spring loaded ball bearing of 8mm would be ideal. (You really can't go too big here) You also REALLY need to get yourself a REAL air compressor if you plan on making "Air engines"..

    Great video! Here's an idea for improvement: maximizing the diameter of the bevel gears could be beneficial. Increasing the lever arm reduces the forces involved while maintaining constant torque transfer. Alternatively, eliminating the 90° turn in the gears and having the fishing wire navigate that turn could be a superior solution. By mirroring the gears transferring torque to the gearbox on both sides of the shaft, forces could be balanced, simplifying your input to just torque. Regarding the hull design, it looks impressive, but you chose a planing hull designed for high-speed gliding. A displacement hull might be more suitable. You could achieve this by reducing the rounded corners to stabilize the boat, utilizing the counteracting momentum generated when the boat leans to one side. Alternatively, a V-shaped hull could be beneficial, allowing for the placement of heavy items like batteries deep underwater, akin to a keel. The beneficial sideeffect is that displacement hulls are also more efficient for your application. Can't wait to for the next version, it is great to watch your iterative improvement process!

    (3:13) I tried printing stacked planetary gears before. You have to make sure that it's not the sun gear attached to the next sun gear. Instead, you have to attach the 1st sun gear to the planet carrier or the ring gear of the 2nd gear system. Otherwise you're just going to run a bunch of planetary gears in parallel, not in series. If you want gear ratio multiplication, you need them to run in series so that they feed into each other. Running the stages in parallel means that only one of the stage does actual work while the other two just spin and add friction to the system.

    I remember installing a chainsaw/weedeater engine in a 6' fiberglass over wood hull. Lots of lessons learned. 1 When you launch everyone gets off the water as fast as possible because you're prop could easily cut everyone else's boat in half. 😂 2 the best muffler is the silicone tube stolen from a coffee pot. ALL SOLID MOUNT PIPES WILL FAIL. 3 A 1/8" FIBERGLASS over 1/8" plywood will easily survive full throttle impact with a tree 30' on shore. 4 Regular hardware silicon makes excellent attachments for engine to hull because it absorbs some vibration. Bolts NO Screws NO. They just vibrate holes in the hull. 😢 Do not give up.

    Maby instead of the fishing line going straight out to this part 5:24, you could put a horizontal (metal) pipe, with some sort of rolling part on. So that you can make the 90° upward turn with the fishing, instead of the bevel gear. 😊

      see my bit longer note underneath @Barkley1835 9 days ago. the proposal is a tri-maran or tri-pod design that is leaving out the pulley and the 90° gears plus even more on your parts list - stripping away items can make things better. what's not there wont ever break.

  • @fridaycaliforniaa236
    @fridaycaliforniaa236 4 หลายเดือนก่อน

    Wait, what ?? Only 7K subscribers ?? 😳😳 *UNDERRATED CHANNEL* ! BTW, maybe you should add a "cage" around the bevel gears. These stinky mofos are incredibly good at wrecking things because of the surprisingly big amounts of force/torque they produce. Also, the planetary gears should be layed at the bottom of the hull. In your configuration, they put too much weight on a high place and it ruins the balance of your ship (she wants to capsize). Also, if you like glass fiber and epoxy, you should make a hull in fibers 😅. I hope it helps you. Sorry my english is as good as the first reel of plastic you used at the beginning of the video 😂

    make the bevel gear a single unit that attaches to the gear/shaft with u joints. alignment wont be as critical and the more solid body holding the gears in place wont flex as much. if you put an axle across the horizontal gear it will have to fight against 2 sides to deflect up.

    You could mount the syringes vertically like stacks and line up all the power transmission along the bottom of the hull. This would put the empty parts high and the driveline low.

    When I make 3d printed planetary gearbox I use thecatalystis planetary gearbox simulator to first check how many teeth on the gears to use. Then removing 1 teeth off of the planet gear and placing it exactly between the sun gear and ring gear. It works all the time on first try. Use normal straight cut gears. Helical gears isnt worth it and make the same noise.

    I would use the modularity of your hull to extend it for another section. Maybe flip the gearbox 180 degrees and shorten the prop shaft and drive it directly. Putting the heavy gearbox low in the hull. In a longer design you could spool both syringes from the same rod.
