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.

    If the air powered Helicopter has energy that is too short lived, you could always build a lightweight steam boiler and use two air turbines to make a vertical take off osprey airplane.

    I guess the nozzle on its own ejects high pressure air that spreads out evenly distributing it's momentum partially in the horizontal direction. This is the same reason rockets optimised for sea level are less efficient in a vacuum. If you had a bell on it to bring the exhaust down to 1 atmosphere it would be more efficient but I imagine that's quite hard to get right.

    What happens if you make a enclosure for the turbine?


    JBEEUD9 soat oldin

    So the final version is very close to a standard impulse turbine that is commonly used in steam applications. Here's a tip. Make two more of those exact same wheels and stack them up with the first in alternating directions. Connect the first and third wheel to your shaft and hold the second (opposite direction wheel) rigid to your frame. Make sure the blades of the first and third wheel are aligned and there you go.

    I think the reason the propeller is more efficient is because the airflow is only utilizing the conservation of momentum (mv). Whilst the propeller is utilizing the kinetic energy (1/2mv^2)

    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.

    treborsnave76Kun oldin

    An idea - a constant stream of air might result in some dissipation of energy as the bucket passes through. Would the concept of a timed burst of air that's synchronised to the rotational speed (think WW1 fighters with timing chains shooting through the props) allow a greater efficiency?

  42. Douglas Carvalho

    Douglas CarvalhoKun oldin

    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.

  79. Deckwolf34

    Deckwolf342 kun oldin

    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.

    @ThaJay Anything that can still shoot out of anything else still has velocity, or it would just fall to the earth. I think the point is to utilize the flow to its best potential, not waste 45% of it.

  89. ThaJay

    ThaJay2 kun oldin

    The whole point was to make it shoot out of the cup at zero velocity so a second rotor would not do anything if it's set up properly

  90. Joe Pieczynski

    Joe Pieczynski2 kun oldin

    @Scott Demoor Naturally at some point in this process, the fuel, be it water or air, will loose its ability to produce power, but that immediate discharge from the cup is very focused and a lot of energy just waiting to be harnessed. I'm not a turbine guy, but I think its worth exploring if it doesn't add too much weight and defeat the application parameters.
