When I look at your water jet nozzles;... 6 off;... The water seems to spray out;... while not being forced into a tight cone like a jet engine trust. Perhaps incorporating a trust shape cone similar to a rocket where the exhaust;... in your case water leaves in a conical shape... Also judging by your wrist being pushed back;... you already have a considerable amount of trust...
@@ElTelBaby Thanks for these ideas, I also got the idea about a rocket engine shape, I need to find out if this can also work for liquid instead of gas. Another thing I want to try is to gradually increase the length of the channel to see if it makes a difference - but I do not want to lose the advantage of the shorter length. Right now the difference is about 20mm in length compared to the "regular" design.
@@mjetdevelopment ? When you was holding the jet engine by hand... Did you notice more trust with it above the waterline or below... I ask because there are marine species the use water to swim in water & a jet plane on an aircraft carrier use a portion of the deck that lifts up immediately behind the jet exhaust trust to increase Newton 3rd law...

How do you guys like the look of it?
Futuristic

So you know. That's using the laminar flow to direct water in a smoother and more liner fashion. Look it up. The videos are really cool.

Cool project and i will definitely follow it 😁
Nice,
Was wondering if there is a design that uses 4 high torque low rpm motors
Thanks. How do you mean? A pump that would be powered by 4 separate motors? Why not just a single big one?
Hi; what 3d printer do you use? thanks
Prusa MK3 with enclosure, this is PLA
Can this being scaled down and printed smaller to fit smaller concepts
Scaling usually does not work well because of bearings, screws and nuts, shafts and servo sizes. How small do you need it to be?
