[@sdhlkfhalkjgd]

I really liked the design walk through. One thing I feel obligated to point out is the lock-wire job as shown at the 7:10 mark. If you'd like to have the safety wire do more than keep the loose fastener from backing out completely, you should always wrap the wire in such a way that the fastener's counter-clockwise rotation increases the tension in the lock-wire. This helps to prevent loosening and is the 'by the book' as they say. It should generally resemble this -> "Ƨ" more than -> "S". Don't take that the wrong way. I've got the utmost respect for the work you do and only offer it up because I'd hate to see that hub loosen up. I'm curious, have you estimated how much of the engines torque you're consuming? It sounds like it could benefit by doubling up the blades. If you have a surplus of blades, it would be interesting to see how well it would scale.

[@TechIngredients]

With the more powerful engine we're going with a ground adjustable, Ultra-Prop II so that we can dial in the pitch to match the torque of the new engine.

[@Hidyman]

Agreed on the safety wire. That's how they do it on helicopters.

[@jeffcard3623]

It would be interesting to see the difference of an extra 2 blade prop for more area, even with the right pitch, if the engine is producing more torque than is being used.

If you surround the blades with a simple wall as in jetski systems or jet systems, it will increase the horizontal push by 25% minimum for approximatively the same power.

[@canadajim]

Agreed. A ducted fan would work great since the wheels do the steering!

[@Not_Sure-i6o]

I don't think that's accurate, pretty sure open air propellers are more efficient than ducted. Two identical jet engines, one configured as a turbojet and one a turboprop, the turboprop is more efficient. The turbojet might reach higher top speeds tho

[@macrumpton]

@@Not_Sure-i6o nope

[@motosk8er2]

Pretty sure they are aware of what a ducted fan is. They literally showed the 2 that they previously used in this video.

[@kadmow]

A well designed ducted fan can create more static thrust (this vehicle is moving very slowly relative to the tip speed) and an extremely well designed duct can be a little more efficient at low-medium speeds, gaining that 25% I posit isn't a "given" without re-designing the impeller / "fan" for the task... At high speed form and parasitic drag of ductwork is usually significant - again it is possible to have ducting generate some thrust, but all the drag can't easily be negated (ie. it isn't free).. Note that Jet engines duct the fan as much for PR, noise reduction and safety... The travelling public are more reassured to fly on a "jet" rather than a "propeller" aircraft.. yes the travelling public are largely "idiots".

[@KeithHeinrich]

I have one of these with a 250W hub drive motor. Its speed limited to 25kmh and is absolutely terrifying. I expect at twice that speed you would definitely be wanting a helmet and brown undies. Sunseeker make a more performance oriented model with better brakes and the wheels cambered for improved stability because if you corner too vigourously or hit a kerb at the wrong angle they will roll. Now you have your mule running, is there a hipo version in the wings perhaps?

[@rowgler1]

I would be scared to try to turn a corner at high speed on a delta trike. The tadpoles are definitely more stable. Check out the Kazebikes AR-3. It has a unique lean steering action that makes it very difficult to tip, even at speed.

[@KeithHeinrich]

@@rowgler1 that is a very cool machine.

Could you not insert a centrifugal clutch so the fan disengages when the engine is idling? Lets see the increase in efficiency surrounding the prop with a shroud.

Awesome explanation of the physics behind thrust efficiency! I'm a jet mechanic for about 24 years now and I still go nuts trying to explain thrust to weight ratios etc of jets, why we use turbofans as opposed to old school turbojets in commercial jetliners and why they're more efficient yada yada and all that jazz.. Wanted to fist bump you guys for this video 👊 - However, I do have a stupid question; With the current prop setup and it's narrow pitch did y'all have any issues with stalling (airflow stall, not engine) and end up having to limit RPM of the engine and such?? That's something I was extremely curious to find out

[@Drmcclung]

Also forgot to thank you for explaining *energy density* which is another concept that just can't seem to beat into people's brains 🤬

[@TechIngredients]

Thanks! Based on the research we did when building these propellers for our drone project it seemed likely that at the maximum RPM of the engine, four blades would be a pretty close match for the rated torque output and this turned out to be true. Stalling isn't an issue as the pitch is pretty shallow, but as speed climbed the engine was unloaded and the governor limited output and thrust. The upgraded engine will be mated to a ground adjustable pitch, Ultra-Prop II to allow the prop to be better matched to the available torque and compensate as the forward motion decreases the apparent angle of attack.

[@Drmcclung]

@@TechIngredients That's neat!! Yeah prop physics get a little bit out of my wheelhouse - the old prop planes I used to work on as a young mechanic, prop governors et al were always "if it's giving the pilot trouble, swap it out and let the manufacturer fix it" and pitch control much the same thing. We were taught all the mechanics of making pitch control work, the oil controls to it etc, but exactly how that functions in practice (how and when to change pitch) and what it does in the air, that all got a little out of my wheelhouse so I thought I'd ask how y'all were doing with a fixed pitch prop.

[@Drmcclung]

"fixed pitch prop" jeez say that 5 times fast! OH BY THE WAY!! I really enjoyed your jet video too; the afterburner, the cogent explanation of how it all worked, that gave me goose bumps! I have the hardest time explaining how a gas generator works to turn a compressor to make more gas to make thrust. When you work on them 10-18hrs a day it gets a little mundane trying to explain it all to people who ask. I just direct them to that particular video now

[@DanielinLaTuna]

Brilliant! Physics was my weakest subject in college; your explanation makes sense to this chemistry/biology grad.

I built ("simulated") a plane in Kerbal Space program, where you had to tweak engine power and blade angle from start to topspeed. Got up close to mach1 speed i think.. depending on air density/height i can search the video link if you are interested, i've shown angle and airflow in it.

About .8 Mach, but a wind turbine that fast would have other limiting problems before that speed such as flutter and surface friction.

I hear you on discussing the manufacturing emissions, in the same breath we should include that internal combustion engines also have emissions involved with their manufacturing along with all the specialised equipment used to harvest,process and transportation of the fuel to be used. Also as an argument of energy source despite energy density of onboard storage. Coal power plants are on average 37% efficient, petrol engines are on average 20% efficient (modern passenger vehicle engines) Coal that's used in power plants is 60-70% carbon, so a kg is 660grams of carbon Petrol is 87% carbon 13%hydrogen so 1 kg is 870grams of carbon, the energy density for the pair is different, coal having 29.3 MJ/8.14kwh and petrol 45MJ/12.5kwh So as far as which option is better coal=10.85 mega joules of usable energy (37% of 29.3) Petrol=9 mega joules of usable energy (20% of 45) Petrol in this case represents, -16.9% less energy for an increase in carbon of +31.81% over coal. ****These are numbers pulled off of Google searches for things like "how much energy is in 1kg of "X" I personally don't believe that either obtains recorded efficiencies, I am extremely sceptical about the performance of the small engine, as motors are dynamic in the range of efficiency/rpm, I am more confident in the power plant efficiency number as that would have been calculated and measured by the companies involved in producing power so they can work out profits, as for small engines, owners are not going to run them at steady state.

weight

[@VistaViews]

Even using lighter material it would be extremely hard to get moving and therefore limited where it could be used and extremely inefficient vs cost to produce etc.

[@LoHK9337]

I assume you mean a squirrel cage mounted on a vertical axis as opposed to horizontal. That is a type of vertical axis wind turbine , or VAWT. Many do have the advantage of being able to catch wind from nearly all directions without needing to be rotated to face the wind. However, they also have the disadvantage of some blades facing into the wind as they revolve around the axis back into position to catch wind again. This can cause the blades to wear faster from changing torque loads. The power output of VAWTs also increases with speed but at a certain point the power peaks and falls off is speed increases further, so brakes are needed, though I believe this flaw may be inherent to horizontal and vertical turbines. I'm not an expert on the subject and this is just what a 10 minute google dive has turned up so I may be mistaken, take it with a grain of salt.

[@TechIngredients]

The mass and expense would be huge. It's better to add diameter to the blades and give up a little effeciency.

One thing worth mentioning is how you choose a prop that is correctly sized for your power output. Optimally, your engine should not reach full rpm in a static run. While this means you won't have the most static thrust, your thrust will be higher at higher speeds and your top speed will be higher.

[@TechIngredients]

This turned out to be a lucky break as we already had the propellers. But, an adjustable pitch propeller would be more flexible and that's why the upgrade will use a slightly larger, Ultra-Prop II which is ground adjustable.

It would help a little, but it would be a real chore to build. The clearances have to be tight to maximize the benefits while at the same time it has to be light and stiff to remain stable as the bike bounces around.

[@GenoLoma]

@@TechIngredients Polystyrene with a layer or 2 of CF, mounted to the existing fan guard, maybe just a thin paper liner glued on the inside face of the cowling where the blades would be close so if they hit, it hopefully wont instantly destroy the blade

[@TennisGvy]

Why are there 30 ceiling fans off to the left?

[@TechIngredients]

We moved the rest elsewhere...

[@generaldisarray]

Excellent work. Nice disco ball, by the way... 🤣🤣

[@ACEFDD]

Thanks for the update!

[@GenoLoma]

Please, Please, PLEASE tell me the co-lab is with those Southern maniacs from Cars&Cameras.. pretty please..! hahaha love the insane stuff they come up with

[@mavos1211]

It’s that time of year to release a distillery video perhaps?

[@TechIngredients]

Working on sake at this time.🙂

[@vernepavreal7296]

And like mini videos on this channel this one will not play on either of my two iPhones yet other videos from the other channels do any idea why this one is different? Cheers

[@JOKing-ku8jg]

Use two engines in parallel, with separate throttle controls. Widen the rear axles to accommodate the extra width of the fans, and further stabilize the tricycle. P.S. don't forget the astronaut diapers ! !!!

[@whatwhatdidtheysay...lyric2373]

I'm not sure if you have already thought of this... I haven't watched the earlier builds... but you could make that into one of those parachute glider trikes

[@sficlassic]

Cool to have one. Not sure how licensing wold go at DOT. So would this be a motor bike or air bike ? Let me know on your thoughts.

[@bradmaas6875]

And when do we put the jet engine on the bicycle? And if your negative Stig isn't up to a high-speed test, give me a buzz, sounds like a blast.

[@yetiman3795]

great video! what is with all the ceiling fan boxes?

[@TechIngredients]

Left over stock from the previous owners.

[@mocmocmoc13]

Sometime ago you mentioned something about liquid metal epoxy. I'm eagerly waiting for that video + product.

[@A-ZEE.]

SIR WHAT ABOUT THE LICENCE. I WANTED TO KNOW DOES THESE DIY VACLES ALSO NEED A LICENCE TO DRIVE?

[@djdrack4681]

So, I watch Isaac Arthur/John Michael Godier, as these topics are my hobby. In Fermi Paradox conversations dealing with unlikely situation of an intelligent species not only evolving on habitable super-Earth (5-20x Earth's), let alone ever being able to reach viable escape velocities to get into space. Basically they'd be stuck on the ground...But this reminds me taht it is equally as troublesome right on the ground: they couldn't have airplanes of some sort...and so lack of easy global transportation would definitely hamper such civilization from reaching stars. Great video as always with great breakdown of this.

[@TechIngredients]

This seems unrelated, but I'll bite. Why would a super Earth prevent spaceflight? It depends on density as the gravity well may not be any deeper and even if it was, there is even now, technology that would allow orbit even if at a much greater cost. Furthermore, civilizations that could travel between the stars would be at least a little more advanced than we are currently. PBS Spacetime did a good video covering the more mundane reasons for why we appear alone. I'm inclined to agree with the simplest explanation.

[@djdrack4681]

​@@TechIngredients While you're absolutely right that density would be very important, let us say the Super Earth had a density >= Earths. Yes: in theory they could totally still lob satellites and unmanned stuff up on suborbital trajectories, deltaV needed to get anything of significant size in stable low orbit would be prohibitive via using rocket tech based on some of the stuff I read (I'm not sure I 100% agree with it) and videos on the topic. PBS Spacetime is great I watch a bunch of their stuff. The notion being that if the gravity was 25-50% more than Earth's, at this point not only would it be difficult to get spaceshuttle sized cargo into space, it'd be near impossible to put it in orbit: and even if you wanted to scale the size of tanks etc up: the added stresses could mean that our tanks couldn't even hold up under the weight of fuel etc. ...And so, while the civilization can clearly see other planets etc: their planet is the hurdle they can't get past, kind of like humanities current issue with not having a reliable way to stop strong cosmic radiation from cooking a spacecraft moment it is outside the protection of a planet. AND. Yes, I suppose it is very loosely related at best. I was just thinking about different transportation methods here + elsewhere (reading about feasibility of blimp tech on Mars or Venus atm for example.). and your references to veocity/thrust/mass being moved vs the mass of the object its working against (the planet) made me think contemplate about the implications of something (say a high speed rail system) on a asteroid colony (likes say Fe-Ni, 10mi diameter)...And that while yes, the asteroid will still way a crapton more than whatever is on the train...depending on the mass of cargo on it, and speeds it is reaching; in space such a thing could have significant impact on sidereal rotation of the asteroid/comet, etc.

[@TechIngredients]

Consider the progress we have had in the last few decades. SpaceX may be very optimistic, but their current estimates place one ton in orbit at 3 orders of magnitude less cost than the CURRENT NASA Artemis launch vehicle. Now extrapolate 100 years into the future, a small interval in civilization lifetimes. Extrapolate 1000 years and getting out of the gravity well is unlikely the explanation.

[@zaflowgalactic]

So when are you attaching wings to it?

[@MrAgentEcho]

You should totally contact ben collins (the actual stig) and have him try it out for shits n giggles.

[@TechIngredients]

Good idea.
