    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.

      Very curious to know what happens if you use an electric air compressor vs using equivalent power consuming motor.

    3. ElmMakers

      How dare you hit Integza like that......

      I fucking Jimmy neutroned

    5. Cantankerous

      I'm not positive about this, but I do have a guess as to why the turbine would be more effective than just the nossel. Hear me out. "An object in motion tends to stay in motion." This is a scientific principle which mentions the conservation of momentum. The air is able to spin the blade, and the centrifugal momentum will carry it to keep going while the air only adds to the speed of the rotor. The rotor can then move more air downwards to produce thrust upwards.

    6. Ojas Maywade

      This was really awesome, can you please tell how to have such great engineering concept and build such cool thing. you can also make a detail video about it.

    7. Mi 28

      You can quickly test for gearing ratios by building a bike gearing system with multiple idlers and a derailer.

    8. fontik

      The final goal of this project is questionable to me, if I would have so many spare time to do such, but at best and in absence of such resources I would just test all with A.I. and close the case.

    9. Happy Boy

      Can you try to recreate this thing: irvision.info/home/eHLSf4ehoMpmrdY/fy-lm-h-y.html

    10. Alan Kong

      Anyway to spin up the rotors before take off. Maybe a second tank that disconnects itself just before take off

    11. Leonard Schönfeldt

      Could you please build an industrial 3D printed robotic arm. Like those who asemble cars and other stuff

      What is the tool used to show the gas flow

    15. Hat Man

      Btw, i think the next development would be to enclose the turbine and nozzle to ensure air isnt leaking out of the system before it had had a chance to impart force to the turbine. It'll require effort to design where you want the exhaust port to be and to achieve a tight tolerance on the turbine so air doesnt leak much around the blades.

    16. Hat Man

      Doesn't the nozzle by itself have inefficency due to Rayleighs number or something like that? I cant remember how it works mathematically because im not great with calculus. If I recall correctly, the most efficient exhaust speed of any propulsion system that involves moving air, is an exhaust speed just slightly higher than that of the vehicle's airspeed. This means that you can increase thrust by increasing exhaust velocity as high as you feel like, but it'll never be efficient if you have an exhaust velocity that's super high compared to your airspeed. If you want to increase thrust while maintaining an efficient exhaust velocity, then what you need to do is move a larger VOLUME of air. Taking that tiny, low volume, high velocity nozzle, and converting the energy it outputs into a much slower, but much more voluminous movement of air by the propeller, greatly increases efficiency without losing thrust (and in fact, you can see here, it gains thrust, in part because its an efficient use of energy). If I recall correctly, part of the reason for this inefficency is turbulent airflow between the exhaust stream and the surrounding air bleeds energy away from that exhaust. The greater the difference in speeds, the more turbulence. Im a jet engine mechanic by trade. This concept was really important in jet engine development. Early jet engines were basically straight turbojets. These allowed for very highspeed flight, but werent very efficient, espescially as subsonic speeds. Early jet engines moved a small volume of air extremely fast, usually way faster than the plane's airspeed. When it came to making bigger subsonic planes like the boeing 707 jet powered, the only thing they could really do with the technology at the time was scale turbojets way up, like the J-57. These engines ran inefficiently, chugged fuel, and honestly... Didnt produce that much thrust compared to todays engines. 4 of them were needed to power the 707, an airframe about the size of a 737... And the 737 with 2 CFM56 engines could probably still outperform it. The issue is basically that youve stuck fighter engines on an airliner. J-57s may have lower thrust to weight ratio and lower efficiency than modern airliner engines, but due to its high exhaust velocity, with a variable exhaust and afterburner, they could easily take planes well past mach 1.... But planes like the 707 didnt need to go supersonic, so you can imagine how useless that feature is. The real innovation here was finding ways to convert small volume, high velocity jet exhaust into a bigger volume with a lower exhaust velocity. This resulted in some key developments. First, splined drive shafts. This allows one drive shaft to spin around another spinning drive shaft. This means components can spin on the shafts at 2 different speeds. Now, you can use the outer shaft to run your compressor blades, and the turbine to power your compressor. This part of the engine is the "core" the actual jet engine part of the engine. And on the inner shaft, you can run a different accessory. In the case of my jet engine, the CFM56, this is a giant ducted fan. And it is powered by a lower speed turbine that follows after the high speed one. This ducted fan takes most of the power from a small jet engine (the core is much smaller than, for example, a J-57), and converts it to a very high volume of air moving at just a bit faster than the high subsonic speeds airliners fly at. This ducted fan moves that large volume of air around the core through a "bypass". This also results in a low velocity exhaust around the higher velocity exhaust from the core, which improves even the efficiency of the core's exhaust. As a result, the CFM56-2B has a bypass ratio (how much air moves down the bypass vs down the core) of about 6:1, about 80-90 percent of the thrust is produced from the bypass, only a little bit of thrust is produced from the core, and the engine over all needed much smaller "cores" that sip way less fuel, to accomplish way more thrust.... This type of engine is called a high bypass Turbofan. Its only real downside vs a turbojet is that it cant fly much faster than mavh 1.2 before literally exploding.... but no subsonic airliner can realistically fly that fast. Bypasses like this are even used to make cooler running, more efficent high speed fighter engines. They however have a lower bypass ratio to increase average exhaust velocity. Basically, bypasses can be tailored to the aircraft's intended airspeed. In the same vein, the other innovation was the turboprop engine, basically what tom is doing with pressurized unburned air. Turboprops are used at even lower airspeeds than turbofans. They also turn low volume high velocity exhaust into high volume low velocity. They can be done either with a free spinning splined shaft like the turbofan, or, I know of some designs that simply gear the prop directly to the core shaft using an appropriate gear ratio. Because turbofans and turboprops are quite a bit more complicated than a straight turbojet they required time to develop.

    21. wirelesmike73

      The turbine-driven propeller blades displace a higher volume of air a greater distance consistently over a larger area, producing more thrust - like the propellers on a helicopter versus the smaller jet of, let's say... a ducted fan. A ducted fan may move a huge volume of air very quickly at high pressure, but, over a much smaller area.

    22. phil langstrom

      i think it would be fun to see you make a rc ornithopter maybe an air powered one

    24. Mitch Wiggins

      This may be weird but I have some ideas I’ve thought of because of your video that really have no other purpose than to be shared with you. Is there a more efficient means for me to share them with you.

    25. Kristian

      Three nozzles at the same time on the turbine?

    26. arno vandezande

      I think the turbune is more efficiënt because it takes more energy to get going but then onze it is going don't have to put a lot of energy in it to keep it going

    27. MiDX

      Try to compress water in the bottle.

    28. Varue

      Hey Tom, I love your videos! I used to want to be an aeronautical engineer but the school was too hard for me and I found my passion elsewhere. Still, watching your videos fills me with joy at getting to see the engineering process. I would love to see another 3D printed airplane video. Something I've been thinking about is using a 3D printer to print parts that are ideal for printing (structurally) like the internal frame of an aircraft, but not the skin. This would help a lot with the weight and allow you to make quite magnificent models that require just a little extra work to get flying compared to a fully 3D-printed vehicle. Just some food for thought... I can't wait to see what you have for us next! Thank you so much!

    29. Koral Deniz Karaüzüm

      why doesnt this man has like 5 million subs

    30. dave insanityinanutshell

      Add an micro aspirator at the air nozzle, this should increase the volume of the air across your turban giving it possibly a 10x increase

    31. Ron Flores

      The efficiency of the turbine decreases if the speed increases and the pressure decreases, what would happen if you design a turbine that runs more efficiently at a lower pressure and reduce the pressure with a simple regulator to keep the pressure longer at the most effective pressure? Maybe slightly less output but for longer time and at an higher efficiency.

    32. grambadamba

      interesting and awesome content! Did you design the pelton turbine by using Reynolds' law of similitude? Would be interesting because we should assume, that the behaviour of the turbine in the same Reynolds number with water and air should be comparable or do I have a knot in my head?

    33. l0g1cb0mb

      I do so enjoy observing the engineers mind at work. inspiration for not only my own works, but for the next gen of makers and such, please continue the good works and the having a much fun doing it!

      I've recently been seeing a lot of stuff on air multipliers, and although I haven't done too much research, and have no idea on efficiency and such, but it'd be interesting to see your take on them

    39. Velvet The fox

      You should enclose the air peice with the entrance from bottle amd exhaust on the chassis offset by a small ammount to increase power transfer

    40. David Wilkie

      Excellent demonstrations

    41. Nooz Zoo

      Create a servo-controlled aperture for the nozzle, and you can attenuate air flow.

      use air to make electrify put one those DVD burner motors aren't they three phase . use it as a generator

    45. Schweet119

      So could you make the turbine a little more efficient by turning the blades 90 degrees, that way centrifugal force is working in your favor too?

    46. OnePalProductions

      Is this what powers the LEDs in my rainfall shower?

    47. Martin Kuthan

      The last option is great, but it occurs to me that the performance at higher speeds will be proportional to the outflow of air. Could a Tesla or steam turbine be used for the same purpose?

      irvision.info/home/k4HAe2uKoKyeaJM/fy-lm-h-y.html check out this video to see what i mean for the "venturi pump" turns out there is already name for this in the aviation industry "aviation aspirator" 4:26m in video, or TLA "tank liquid agitator" its the same principle. who ever in your setup i assume some sort of valve will be required due to the small amount of air available. (my idea is to use this to lower the comsumption of the system, but i guess it could be used to add power instead). up to you to chouse the best aplication.

    59. Matthias May

      Place the nozzles on the tips of the rotor blades. Some early helicopters had this design. It had done trouble with hit gases. Since you use cold compressed air there should nothing to be worried of. Placing nozzles on tip of the rotor will drive the rotor and save the weight of the turbine and gear.

    62. Alexander Kosolapov

      Try to split the incoming stream in two halves and turn them towards each other so they will cancel each other's energy.

    63. Alexander Kosolapov

      Try to curve the bucket in way that the water (or air) gets redirected back to the incoming stream.

    64. Camille Cirrus

      My favourite part is where he bats integza off the screen with a bottle.

    65. Shun Ryuenji Matoi

      Enclosing the turbine might improve efficiency a bit as its less drag from the sorrounding air. The real question here is how is the exhaust gonna be made.

      Thanks Tom, as always, well done and very informative!

    70. Mr.McGoover

      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.

    71. Tatskaari

      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.

    72. Flare

      is anyone gonna mention the linear flow at 5:15 ?

    73. Guy Fallon

      Tom ur a wild man ! thx

    74. Lukas Zieba

      Super cool dude. Keep it up.

    75. Terje Svendsen

      What happens if you make a enclosure for the turbine?

    76. JBEEUD

      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.

    77. Théorie de la Gravité

      Hello Tom did you try with vacuum? How to made it? Surprise me...

    78. Kofichi

      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)

    79. joe cool

      i love this sort of stuff, always been thinking about stuff like a hydrofoil piston etc etc blah blah .. i won't bore you with a details and can't find the only one on youtube someone made in a jungle in thialand somewhere .. you strap it to a rivers bridge and it pumps up and down ... basic stuff

      It would be nice if you used grams instead of newtons, it's easier to picture the weight

    88. worstthinker27

      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.

      Are you sure it is a good idea to place you UV 3d printer near the window in a daytime? :)

    90. AMV12S

      What about a hybrid? the air turbine plugged to a generator to charge a battery that runs a motor with the propeller 🤔

    91. Steve Lacy

      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.

    92. Skillful Man

      nice work , love your data analysis

    93. Wayne Page

      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.

        This vid is the history of steam engines from piston to steam turbine. I expect the conclusion is a 16mm multi-stage blade set with reversing blades between them?

    94. Blood Sweat And Tears Forever learning

      Incorporate a pelt wheel into a turbo, the bigger the better because the air has more time to travel through my system

        Wouldnt a francis wheel be the best for this? Efficient and the exhaust can be faced down to add to verticle thrust.
