The resin printer is the Elegoo Mars 2 Pro and I was using the standard Elegoo clear resin. I was tempted to build a custom UV curing station, but ended up ordering the Elegoo Mercury Plus 2 in 1, which I definitely recommend as it makes the post processing far easier. As mentioned in the video, none of this was sponsored/provided by Elegoo, I just saw it all on Amazon Prime and thought I'd give it a go.

    Just looking at the thrust equations: for a turbine driven propeller its thrust equation is proportional to V^2 while for the nozzle its thrust equation is proportional to just V. Turbine Driven Propeller Wins. Also in order to get more juice out of that nozzle, you would need to create the right pressure ratios, converging/diverging nozzle, etc. to expand the flow isentropically as close to the back pressure as possible for max nozzle efficiency.

    I wonder if using a denser gas like CO2 or N2 or Argon would help? All are fairly easily attainable at a Welding supply store. Might be a good power/weight ratio test. In fact, I wonder if putting a few grams of dry ice (solid CO2) into the canister would work out well on that front. Certainly give you more than the 30s of runtime at a fairly reasonable weight penalty.

    Interesting, it would be interesting to hook this up to a large pressure plenum and modulate the pressure as the form of velocity control. There might be some good reasons behind pressurizing the bottle to a max pressure and using a small pressure regulator to keep the max thrust a little bit lower and prolong the time of flight.

    The reason why the turbine is more efficient is because the 2nd and 3rd Laws of Newton. Less air mass is displaced with the nozzle only configuration, hence less force is applied and less reaction happens to the opposite direction. That's my guess.

    what about a turbine where each "blade" or "bucket" splits the airflow into two paths but the 3dprinted cross section of the blade includes a section from a tesla valve, so you take some of the incoming air and redirect it around to create a high pressure obstruction, which also pushes back pressure in the second chamber and pulls more energy out of the air slow? the problem is the time each blade is in contact with the stream is minimal, and then you have to deal with the effects it has on the rest of its journey around.. hrm

    7:25 For why the turbine-propeller contraption is more efficient than just spitting out the air, it is the same stuff as why turbofan engines with large fans in front is more efficient than turbojet with afterburner. The amount of force (thrust) produced is affected by 2 major factors, speed , and mass of air moved. By spitting out the air out of the nozzle, we get air on very high speed, but only a small amount of air is being ejected. However, as long as the turbine contraption converts energy good enough that it could push way more air down with slower speed that higher force can be achieved and thus more efficient.

    I would think that the nozzle, alone, is less efficient because the air being ejected has no solid surface direct beneath it. This causes the compressed air to spread outward, giving a third of the horizontal motion, the other two thirds becoming vertical motion and not creating force on the same axis as the measuring instrument, but this is simplified to a two dimensional plain. In reality the true horizontal motion is a lot less than on third; this contradicts your graph, but the graph doesn’t show the true horizontal motion. Your graph also includes the air being disbursed at all three dimensional angle between horizontal and vertical angles (i.e. between all 90* on the x axis set in 360* on the z axis) with each consecutive angle having decrease amounts of force from the true horizontal motion. edit: The net force of the nozzle would be a little less than 1/5 of the net force of the nozzle and wheel.

    If there was some way to maintain the downstream pressure, could you improve the performance of the application? Rather than having the force decreasing over time, you’d have a more constant force which can more easily be applied to a mechanism. Something such as a pilot-operated pressure reducing valve would be cool to see but I really don’t know if this is at all feasible with air and at such a small size.

    Fun fact: the turbine wheel you've created is called an "impulse turbine" and the devices that direct the flow into a gas turbine IRL are called "nozzles" even if they don't look quite as literal as what you've got going on here. If you want to increase efficiency and/or decrease mass, make the turbine inlets only as wide as or a little wider than the outlet of your nozzle.

    Mr. Stanton: I would suggest you use a 4500 psi Carbon fibre paintball tank (smallest size 13 ci) and a first stage Hero reg followed by a second stage Polarstar Micro regulator. This allows the use of a LOT of compressed air in a regulated fashion. As you know this means your nozzle(s) will continously blow at the same speed rather than drop off quickly. It also means you have a lot more air to work with. When powering multiple props (which is what you aim to do with an air powered drone) you will easily create the lift needed to raise the tank and reg setup and the rest off the ground. Hanging the tank vertically below the prop level will help balance the drone while it travels upwards. Hope to see this happen in one of your follow up video’s. You really want to prove sustained flight is possible. I believe this to be the way! Kind regards, Marten

    Just a thought. The pelton wheel is driven at one or a few points and the rest of it's travel the buckets aren't producing. They are actually wasting energy churning the air. This is acceptable at the speeds it operates due to the difference in density between the driving water and the resisting air, and the buckets being small and not catching much air. When you switch to air, the turbine spins much faster. Now those buckets that weren't doing much for 90% of the rotation are catching air and working as a fan. I think to really improve it from here you will need to design a turbine that is supplied pressure on all the blades at the same time. With such a small supply, this will be tricky. I am thinking a tiny diameter to reduce the circumference, and tiny blades as all must be supplied. At this scale though you will be getting into laminar flow which behaves differently. You could also try four nozzles on a smaller turbine, but it may be difficult to make the nozzles small enough. That should reduce losses. I think you may find this book helpful.

    I noticed that a lot of air is going into the void around the turbine blades. What if the turbine is enclosed in a closed housing so that the air moves along its entire circumference and exits near the nozzle. Also, make the outlet directed downward so that the remaining energy gives an impulse in the right direction. It seems to me that this would increase efficiency several times. Sorry for possible mistakes, I am using a translator.
