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.

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.

@randomguydoes2901 2 года назад

Yup it'll be more efficient until the speed and aerodynamics of the propeller (turbulence etc) get in the way of achieving really high speeds for our theoretical aircraft. Is why we don't have supersonic prop planes, and also why we don't often use small jet engines to go slower (jet = less efficiency = more fuel needed = need a bigger, heavier plane to carry that fuel = it's now fast enough but definitely need to fly at a higher altitude to reduce wind resistance a bit, prop planes lose torque and are generally slow enough to be better off at lower altitudes)

@IncroyablesExperiences 3 года назад

The reason the turbine is more efficient is the power proportional to S*V³ while force to S*V². With the same power it's more force efficient to use a higher surface with smaller velocity. The greater surface (S) of the prop allows to reach a point where the propulsive air velocity (V) is just a bit higher than the "plane" velocity (here 0). To produce static thrust it's in theory possible to get an infinite force to watt ratio (force isn't energy) with an infinite propeller diameter. But the force to weight ratio would be awfull and impossible to run a plane because the max propulsive velocity would be near 0. Soo interesting (as always), thanks a lot! 100% pure engineering satisfaction! Keep going :D Favorite channel for 2 engineers

I think the reason why the turbine has more thrust than just the nozzle is due to the fact that the turbine powers a propeller. The propeller moves more overall air than just the nozzle. Basically it's the same reason why turbofans, especially the high bypass turbofans, are more efficient than turbojets.

I'm blown away. I never in a million years thought any more thrust could be made than just the air nozzle itself. Seems efficiency would go down. This is some game changing content.

@tuck1726 2 года назад

Angular momentum helps as well, but by proposal is the air having the same buoyancy when not compressed as surrounding air means force has to be used to displace air it's traveling through. The turbine does not experience this as much because it's not traveling as far and you could add a cone around nozzle such that the air that's deflected goes around it creating vacuum at novel. I would suggest a gas that is less buoyant than air and camering turbine where air goes downward then extending blade such that the air escapes when turbine moves up hill.

@tuck1726 2 года назад

Also the diffusion of air outwards from nozel exerts energy outward that's wasted from not going downward

@AlRoderick 3 года назад

The thing with air is that it has to have some kinetic energy left, because it has to push other air out of the way to exit the turbine (Betz limit). Water would do the same if there wasn't a downstream drain under a dam.

@corentinoger 3 года назад

@JainZar1 3 года назад

The Betz limit is also the reason why the ducted fan/turbine works better, as the less turbulent airflow at the blade allows more energy to be transferred to the mechanism and not be wasted into heat.

@kwarrtzorau7203 3 года назад

7:20 By driving the propeller instead of using the nozzle directly, you're moving a larger mass of air at a lower velocity to get your impulse. Since kinetic energy goes with velocity squared, while momentum goes linearly with velocity, this gives you a greater total momentum in your reaction mass for the same kinetic energy, and thus you get more thrust.

@oadka 3 года назад

And not to mention that he can get twice the force with the turbine than by just pushing due to the 180 degree change in flow direction in the turbine compared to just 90 degree effective change when the nozzle is used directly.

@wire3989 3 года назад

Yeah! with a propeller It’s a higher bypass engine.

@mandernachluca3774 3 года назад

You would have to explain that to me. Your impuls or momentum also goes squared with velocity. I=(V^2)*roh*A=V*Q Q being the massflow= V*roh*A A being the active surface area V being velocity I being impuls or momentum roh being the density of the working fluid (air) I think that the magic trick is the ratio between the coefficient of drag and the coeficient of lift of the propeller. Everything else should not contribute to higher efficiency and higher thrust. The total impuls of the compressed air is basically getting transformed from a high power low force, to a high force low power configuration. The max rpm of the prop should thereby limit the max velocity of the vehicle. Why is unclear to me, as turbinejet and rocket aircraft are only limited by there thrust wich is impulse, wich in tern should also applie here, but would make no sense anymore if it could.

@mandernachluca3774 3 года назад

Never mind, took me about 2 minutes to find out, that the propeller pitch limits the rpm. To high of a pitch angle and your needed torque to turn the prop is to high, to low of a pitch angle and your propeller will overspeed or simple induce to much drag at higher speeds. You could also explain it with force vectors. As the pitch increases, so does the angle of the lift force vector compared to the normal vector parallel to the prop shaft. This in turn decreases the part of the velocity vector parallel to the normal vector, thereby reducing total thrust.

@luelou8464 3 года назад

Pretty sure that is it. Force is mass flow rate multiplied by velocity change, power is mass flow rate multiplied by velocity squared. If you quadruple the flow rate, then with the same power you'd get half the velocity, which works out to double the force.

@@GigsVT Actually no. Bell nozzles are there to collimate the plasma. In the converging section, the particles are moving rapidly in random directions. (High pressure & High heat.) The expanding section the plasma is forced to expand backward, exchanging pressure/heat for velocity. In a perfectly calibrated bell, the exhaust leaves at the same pressure as the atmosphere. If it's under-expanded, it will expand outward in all directions and that energy is lost.

@pilotofjet 3 года назад

Your nozzle only is not designed to extract all the potential energy stored in the pressure. In order to improve its thrust you might have to design a convergent-divergent nozzle made to accelerate the flow as much as possible for the ambiant pressure (an adapted nozzle) At 4 bars of pressure you are effectively in the range of pressure ratio where you can have supersonic flow exiting a carefully designed Con-Di nozzle. In order to design your nozzle you might have to explore different throat areas as a trade-off between max thrust and how long it lasts. then you can go on calculating the adapted exit area using some isentropic compressible flow relations. If you wanna go all out you'll also need to find the optimal nozzle shape which is a whole other story but described in some compressible flow books.

@Dilongparadoxus 3 года назад

That's a good idea, and i definitely think tom should try it out! However, you still wouldn't get as much thrust out of the jet nozzle as you get out of the propeller. A jet is most efficient when the exhaust velocity is relatively close to the speed of the surrounding air. That's why fighter jets use afterburning low-bypass engines with high exhaust velocity to go fast, airliners use high-bypass engines with high mass flow at relatively lower speed, and even slower planes use turboprops.

@LazerLord10 3 года назад

hmmm... is it less efficient because the air has a 'venturi' effect where it wastes energy by accelerating air that's on either side of the nozzle? If that's the case, a dutch on the input to the turbine could be helpful.

@gameonyolo1 3 года назад

No it's the same reason that commercial airplane engines get better. Idk but something about more mass means more efficient

@miron__ 3 года назад

@randomneko9 3 года назад

Honestly I thought it had something to do with the air pushing directly against something. I am not educated on this, I'm just an IT field tech, so this is purely guessing. But my thought is that the jet of air alone is only acting on the nozzle. The energy is lost rather quickly into the surrounding area and only transfers energy to the nozzle as it exits. If you put something in the way of the escaping air now it has to transfer its energy to the object in front of the nozzle too. I bet a simple flat bladed wheel will still produce greater thrust than the nozzle could do on its own.

@Avetho 3 года назад

Oddly enough this reminds me of a video a while back from a youtuber called Stratzenblitz, in a game called KSP he built a flying aircraft carrier, and it only had 12 jet engines for thrust which was magnitudes lower than required to lift its runway sized bulk off the ground, but since he directed the jet engine exhausts at these absolutely massive turbine rotors made from dozens of wing surfaces, the jet exhaust made the giant rotors spin, and it could lift its couple hundred tons and oniboard aircrafts off the ground. So I believe the propeller is more efficient than the direct nozzle since the nozzle functions up to a high velocity whereas the propeller has a very low maximum airspeed. It can be thought of as gear ratios in a car as well, a car can move more weight in a lower gear at the cost of a low top speed.

@PKMartin 3 года назад

KSP can be tricked into breaking conservation of momentum. The thing you're describing sounds like it's possible (using engines to spin a big rotor producing more thrust than using the same engines as jets) but just because it's possible in KSP doesn't mean it's possible in real life. There's also a glitch where you move fuel from one end of a spinning space station to the other and it creates momentum out of nowhere because the fluid dynamic model isn't detailed enough.

@Avetho 3 года назад

@@PKMartin I get what you're staying, and it makes sense since in KSP the force exerted on a part due to the engine exhaust is very static in nature only varying with throttle output (there is no kinetic energy loss from gas billowing out the clearly open sides), but the theory behind it is somewhat sound. Its not conservation of momentum being broken in this case since the jet engines at full throttle which can fly reliably over Mach 2 (686m/s) are exerting force on the turbines which can propel the huge helicarrier at maybe 40m/s through the air if I'm being generous and gravity is disabled, so the thrust is all in the direction of motion. Its trading off airspeed for more static thrust, similar to how jet engines that are very high bypass (huge fan diameter) are used in subsonic heavy aircraft whereas low bypass are used in supersonic aircraft. Its all about the airspeed in the end. High lift coefficient and low airspeed, or low lift coefficient and high airspeed? That's the tradeoff between jets and large jet-powered rotor blades. On another note, its always really fun to break KSP's physics engines for fun and profit lol, the beautiful wonderful Kraken Drive XD

You just invented an axial gas turbine starting from a water turbine! Man you're a genius. Seriously, nice explanation of impuls, speeds, momentum, power etc. Maybe a visualisation using vectors can show how simple it actually is to design turbines.

7:13 Regarding the nozzle only having .34 newtons of thrust on it's own, I'm curious to what degree an engine bell could increase that.

@fg8557 3 года назад

By exactly 0% as long as the inner diameter is too large to reach supersonic velocities. Even then, a conical nozzle can reach up to 95% efficiency. Bell nozzles are only really needed in rockets, as they can be built shorter than other geometries for the same expansion ratio

@tanyesil 3 года назад

@@fg8557 so what if he got supersonic how much can that benefit?

@zuthalsoraniz6764 3 года назад

Since the pressure ratio is at least initially high enough for flow to be choked, exhaust velocity then can be taken to be equal to the speed of sound, or ~340 m/s. Assuming the 6.9 bar is gauge pressure, and expansion is to 1 bar of pressure, with a starting temperature of 293 K an ideal nozzle would be able to get ~520 m/s of exhaust velocity, or about a 50% improvement. However, the nozzle would drop off efficiency fast, especially as a constant expansion ratio nozzle would either have to seriously underexpand the flow at the beginning, or end up severely overexpanding it at the end as pressure drops, and both are bad for efficiency.

@Aetius90 3 года назад

You can improve your turbine by change the turbine configuration. Check for centrifugal turbine and blade design (they are in function of air flow angle and speed). You might also want a stator stage before rotors.

@mastprani 3 года назад

Hey Tom! It's always enlighting to watch your videos. Loved this one specially. I believe the efficiency of your air turbine can be still increased. What of the turbine and the feeding nozzle is placed within an casing, to avoid the loss of air pressure when the air hits the propeller. And with an opening behind the air can exit from the turbine assembly.

Could you power the helicopter with 12g CO2 capsules or would they be too heavy? To eliminate the weight of the assembly that holds the capsules you could get the ones with treads on the end (or make treads on a lane) and connect them to your system with a higher pressure hose.

@fg8557 3 года назад

That was also my idea. But the CO2 will liquify when expanded through the nozzle

@mmic6691 3 года назад

@@fg8557 depends on the nozzle type and outside air temperature. But considering these co2 are used to pump tires or as propulsion for pellet guns its most likely fine. Such a small stream would heat up quickly and will probably not be a problem. It's not like you will release all 60bar in 0.1 of a second. But there could be a problem with the nozzle freezing... I do think it's an interesting idea to test.
