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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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!

  • 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.

(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.

  • 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.

    Mr.McGooverMr.McGoover10 days ago
  • 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.

  • 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.

  • 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.
