Water Rocket Skateboard (3D Printed)

[@assamite9614]

When RPM is too high You will get a lot of air trapped inside, submerge the pump in water 1st.

[@MaxDeVos]

Exactly, even when the battery isn't charged you can see air in the chamber. Liquid pumps need to be primed. It will probably also slow the engine down a bit but I doubt the prints can hold.

[@marv8481]

Also needs to change the inlet and outlet. The inlet piping does not need to be necked down right at the inlet and the 90 degree bend needs to be have a larger radius, this also causes cavitation as it throttles centrifugal pumps a lot at the inlet. The outlet needs to be longer before the nozzle is put on. All this will increase the pumps efficiency. As long as the water level is higher then the upper most part of the volute is will self prime and air will get pumped out. But he also needs to start it a little slower and potentially give the veins of the impeller a larger radius as well as making it a “semi-open” impeller.

[@jiimz]

Water is not that compressable, however, gasses, are. If you have a pressurized cylinder of gas and discharge it into your sealed reservoir, the liquids will be accelerated out at a high velocity. The nozzles can then be optimized to direct that water. FDM nozzles may be better for the pressure than resin ones. They have more give. Do this before you mill something out of metal.

This is also why working with high pressure fluids with air inside the lines is quite dangerous. If the hose bursts you have a super fast stream of hydraulic fluid coming out and it can and will pierce your skin. Whereas if you have a system with no air and something bursts it’ll just release a small amount of fluid, given that the hoses are not expanded too much.

Priming a centrifugal pump is required only when the pump is above water level. In this case, that's not true, so priming isn't needed or more accurately it was already primed. Cavitation did happen tho, because of the bad design.

So that you can have a smooth flow. (remember what you were holding in your hand at the begining of the video). * You must be sure of filling the pump with water totally before running. Otherwise, this will be a demonstration of what happens when you run your pump with two phase flow (gas and liquid).

Video Idea: Cold casting: a long time I saw few videos on KZbin regarding casting a resin part using silicon moulds, the fun part was that they were using steel powder mixed with the epoxy resin so the final product was a "metal like" part which later on they sand it and apply acid so the model looked rusted. I search alot on KZbin and was not able to find any scientific test on this method, what are the propreties of this type of material ? are they magnetic ? can it conduct electricity ? are the mechanical proprieties similar to steel ? and finally: what temperature can it handle ?. The ideia is: 1 - to print a 3d model. 2 - make a silicon mould using this model. 3 - create a mixture of epoxy resin and steel powder (20/80 for example) 4 - cast this mixture in the mould and test the final product. I had this idea watching your videos and all the times you use the porcelain resin, to be honest I don't think will work for temperatures above 500ºC because the highiest temperature resin that I found was around that. Never the less all the others possible proprieties are very interessing, being able to "print" metal parts seems very interessting. Hopefully someone will read this comment, If you read until here please forgive my english since is not my mother language and let me know what you think about this idea, i really wanted to test by myself and record the process but I don't have the tools (aka 3D printer).

I've seen a few people comment about the direction of the impeller blades... Impeller blades can be forward-curved, backward-curved, or even straight. Broadly speaking: --Forward-curved blades produce flow tangentially to the impeller, as the blades are actively pushing the fluid. This type of blade can easily exceed the drive rating of a motor at higher flow rates if improperly designed. These really need scroll/ volute housings to be most effective. They are better for high flow rates at low running speeds and lower pressures. --Backwards-curved blades produce flow radially, as the backward-curve creates negative pressure behind and along the length of the blades, and positive pressure in front of the blades. They offer significantly higher efficiency than forward-curved blades, function well at higher pressures, and offer greater suction characteristics as a result. They also don't need volute casings to be effective, though work better with them. --Straight blades are a bit of a mix. They are rarely used as they lack the benefits of either design and offer lower blade stiffness thanks to the lack of curved geometry. For this application, the backward-curved blades are certainly more appropriate. The pump would definitely benefit from being primed, ie filled with water before running. The air in the impeller is significantly hurting performance. Plus the thing might not explode if it spun under a higher load, which would be the case if there was no air on the system. In industrial applications, pumps are almost never run/ started 'dry' for these exact reasons.

There are air pockets created inside the housing of your pump as it spins, this adds additional varying stresses on all your components as centrifugal force has varying effects on materials when run through varying mediums. Thus compounds all stresses and that is why it breaks. For fear of leaving too much to read here: Try adding "step up" pumps from your feed tank toward your 60 000rpm pump. This should fill the gaps better and be beneficial in adding some equilibrium throughout the running process. I can make more detailed suggestions if you are keen.

I’m interested to know why the blades are “scooping” away from outlet as opposed to a traditional impeller design. From video prospective, wouldn’t it be better if concave side was pushing water?

[@vizzair]

Yea it looks like the impeller is backwards

[@oxseth87]

Becuse you are trying to "push" the water out, not scoop it inn.

Video idea: When you perfect metal jet engines, send a rocket into space!

[@alyssyon]

This requires shit ton of papers and bereaucracy

[@Surya_Singh_Thakur]

You obviously need a better propeller for the pump! (Flat type should be good) 😁👍

[@brandonwilliams2770]

you can put the water jet on a boat so that the intake will be under the boat in the water and the output will be behind the boat in the water :)

[@mr.monkeyface214]

Video idea: strap a jet to a plane. We need more air travel.

[@m.d.kulkarni9045]

Make a drone which has mini rocket engines (solid fuel) Which gives sudden boost to the drone

[@timbercook6833]

That's a great idea

[@rutuparn6188]

Ya just like after burner

[@rutuparn6188]

It would be tough though

[@coltenhargett461]

Video idea: you should team up with Peter Stripol to make a combustion engine powered airplane

[@chazztolzmann3222]

You do a good job with 3D printing I can't see anyone else doing as good job as you do keep it up you do a good job

8:17 isn´t the wheel in the wrong direction.I think the open curves schould spin in the direction where the water flows.

[@No_Way_NO_WAY]

That would mean, that the water gets directed upwards near the exit and basically turning circles in the pump reducing its waterpumping capabilities.

[@toby530]

@@No_Way_NO_WAY Okay i thought that it would spin more water and so more water would be pulled outward through the centrifugal force.

[@No_Way_NO_WAY]

@@toby530 fluid dynamics its pretty annoying because its (at least for me) counter intuitive what the fluid does. Was working on a device that protects the tap from waste water in a machine. There are solutions out there that work and are cheap but they are no longer according regulations and the other ones that are still according to it, are much more expensive. And the water never wanted to do what i intended with it. Sometimes jumping a gap, other times it didnt (especially when i wanted it to jump the gap).....

[@toby530]

@@No_Way_NO_WAY okay, maybe you can use for your problem some fluid simulation program, so you can see what it would do before you make it in reallife.

[@No_Way_NO_WAY]

@@toby530 a cheap simulation workstation costs around 20k a year. And my project was the only one that neded one => no purchase. And now the project is the nightmare of a former coworker because i left the company.

Video idea: make an electric rocket engine

[@ouzayb3167]

hey you should print a rocket with hollow walls to fill with water to raise spesific heat and stop burning. maybe you could even make it running water to provide active cooling

[@super_slo]

Ducted steam channel out the front around the back, let the phase change help control heat from the burning fuel and add a little extra thrust from steam?

[@Laylander]

The impeller's design is what is causing it to break, not the speed. Your blades are perpendicular to the incoming water, so you're pretty much just 'slapping' the water 3000 times per second as it enters the pump. You're also creating a lot of cavitation (imploding bubbles behind the blade) which eats your blade away. Angle the blades at the centre of the impeller, so it scoops instead of slaps, and then gradually let it straighten out as you go to the outside and to the bottom. Also, build the impeller blades on a cone instead of a straight shaft. The bottom centre part of the impeller is't going to do much work, so you're better off using that space to smoothen the flow.
