You’re out here doing things with my code that I didn’t even think were possible! Awesome progress on such an ambitious project. Can’t wait to see the fuselage on there
It’s so awesome!
That is because your code is magic, I want to try it my Winderstal wobble-copter
@@magicalpencil Design by David?
Why are we here in this life ?Why do we die? What will happen to us after death ?
@@nevergiveup5939 Wow, a spambot posting existential questions? Now that's new.
I had no idea motors could be controlled so precisely and so quickly. Amazing idea and execution, mate.
Tom really is a bit of a genius.
Same here I figured the momentum would stop it from being able to be controlled this way. That's a genius way to go about it.
As a mechanic I know engine management looks at the crank signal and can also tell when it speeds up or slows down. A 4 inline cilinder fires every 180 degrees. Spark or diesel fuel injection is done with similar timing needed for running a brushless motor. With brushless you need very fast coil switching with correct timing before or after each permanent magnet. So many times per second and within a degree of rotation accuracy, it's mind boggling fast for a human
@@Fantaman900 This is what I'm sayin', it's incredible it actually works.
Better make sure the motors are sized up a bit along with the voltage and current controllers, because constant rapid changes like that are an express train to burned out electronics.
When I was 14 I watched you make interesting RC-planes.
Now I’m 20 and studying to be an engineer partly because of you.
And your videos have advanced so much i’m just in awe every time I watch your newest one.
🇳🇴🇬🇧
What kind of engineer do you want to be?
heyo, same situation here :)
Now 20 and in the first semester for electrical engineering. Stantons videos definetly are a good example of trial and error mixed with a good feeling and proper work.
@@DeadlyWarrior45 im studying to become a mechanical engineer, and I’m planning on going civil❤️
@@raphaelwelti6632 nice❤️ first year for me too. Definitely challenging but it’s good don’t you think?
@@benji376 well it's definitely not easy... But I think worth the effort. Else I wouldn't do it
This variable pitch technique is nothing short of amazing.
it’s practically organic! most elegant.
Came here to say the same thing!
One possible way of making it even more elegant, would be to replace the pivot with a flexible hinge that has bending-torsion coupling; or better yet, if you make your own composite blades you could bake that coupling into the fiber orientation. Not sure itd be easy to obtain the required amplitude in such a way though.
@@eelcohoogendoorn8044 I'm guessing you already have a degree in civil engineering? With the complicating dynamic construction idea? You should start your own RUclips channel 😉
It reminds me of the hacks people in C64 demoscene did :) Like the computer supported 8 sprites but people changed the memory while the sprite chip was drawing them to reuse them on the same screen many times :)
@@jamiewatkins4178 Its not a very original idea; torsion-bending coupling and how that relates to fiber layup is already something you need to pay attention to in the design of wind-turbine blades.
Best practical engineering channel on RUclips hands-down.
Bad obsession motorsport gives it a good run
Stuf made here is cool too ;)
Hey I sub to both of you guys very kind of you to complement him , both your channels are amazing, thank you to both of you
Hadn't seen your old helicopter video, so the solution to accelerate / decelerate using the BLDC motor multiple times a rotation was completely new and SUCH a great idea, taking full advantage of the capabilities of the brushless motor. Awesome video!
Very impressive. As always , I don’t know another channel that brings engineering in the RC hobby so seamlessly. Always pushing forward . Keep it up
You should check out RCTestFlight if you like rc and engineering
@@BenBike love him, he has awesome projects, but I think Tom is more on the engeneering side of things, he thinks a lot outside of the box and his projects are well refined with cool building techniques
@@BenBike Definitely a good recommendation. The multi-element STOL wing design and ekranoplans along with many other projects are pretty cool. Though, I don't think they bring engineering in the RC hobby like Tom Stanton, but this guy's setting the bar so high that it's almost unfair to other channels, so RCTestFlight is definitely still worth checking out :)
I apparently need to go back and watch your last video about the single-motor variable pitch blade. it's absolutely astonishing how well that works. Gaining degrees of freedom by modulating a single output and not adding an extra motor OR controller is brilliant. Awesome project!
edit: does flying that way take a significant efficiency hit? I'd guess that with a sufficiently complex controller, you could get regenerative breaking for half the cycle, throw a mid-size capacitor inline with the controller and be in business! Part of me was wondering if a "real" helicopter could be built this way, but it seems like you'd need a lot of extra complexity to dynamically oscillate the speed of a gas engine output and the standard mechanism may be easier?
I doubt very much that a gasoline engine could be made to do this by itself. That said, it would be almost trivial to introduce the necessary sinusoidal rpm oscillation. Improperly clocked u-joints on driveshafts already do that, for free. All thats needed would be some sort of mechanism to skew them in and out of time.
U joins oscillate their speed twice per revolution, so you’d need to gear up the output by a factor of two. Your u joints would have to be able to handle a hell of a lot of torque.
Wouldn't this mechanism with a chemical engine require either a mechanical system to quickly reverse the direction of the motor's torque many times per second, or a braking system to reduce the speed of the motor? I'm not sure if the former can be practical, and I'd imagine the latter would at best wear down the brakes extremely quickly.
Actually, I wonder if you could use special gearing to achieve the effect. I assume the way that the motor works is by rapidly accelerating the motor, to adjust blade pitch one way, and then by letting it naturally decelerate to prevent the blade pitch from going the other way? I think you might be able to accomplish this with spiral / shell gears, like in this video (ruclips.net/video/0wEtyzgnEY8/видео.html) but less extreme. Alternatively, I think an egg-shaped or elliptical pair of gears could work, if the axis of rotation is not in the center of the shape (maybe in a focus of an ellipse?) With a constant motor speed, the driven gear would rapidly accelerate regularly, and then slowly decelerate. This would correspond to a blade pitch that is asymmetric over time and could be used to control the aircraft.
I think you could make a design that could (theoretically) work from a constant motor speed. You'll want to have what is basically a manual transmission, but instead of each pair of gears changing the torque/speed by their ratios, you have pairs of shell / spiral-shaped gears with different curves. Oh, and you'd have 4 counter shafts, each with a different shell gear paired to one on the input / output shafts but rotated 90 degrees. Each of these shafts would accelerate the motor (and thus pitch the blades) at different places along the blades' rotation, and thus would correspond to asymmetric lift in different regions to control the aircraft's pitch.
There's probably a way to use only 1 counter shaft instead of 4, and bonus points if you can create a continuously variable transmission that's spiral-shaped to change the rate of pitch change.
I hope this comment made sense, I dropped out of engineering and learned terms like 'counter shaft' and 'shell gear' just now while searching on wikipedia for how to explain my idea.
You’d loose some efficiency right off the bat with the conversion, but you could fly-by-wire the main rotor in the most literal way: converting the gas to electricity and then electrically modulating the motor, but I think that whole assembly would certainly loose on complexity and cost to a standard helicopter
@@luelou8464 hah, yeah they would for sure. I wasnt really thinking about in a practical way, but just from a "this is a way it could be done" way. Yeah there would be challenges there for sure, probably not worth it given that the swash plate mechanism already exists. Electric motors just have so much better response rates, so its possible to cheat (in an honestly brilliant way, I'm baffled that this works at all, especially with commercially available speed controllers, and not some custom solution)
Your ability to intuitively trouble shoot these incredibly complex designs is beyond impressive
Your methodology for testing is incredible. It's logical, and quite calming to watch. Great build!
This. Is. Amazing. I love the fact that you show all the steps taken to test and build this aircraft. Pure engineering channel !
Love to see the swashplateless tech coming back on this channel!
Very clever Stanton - your lateral thinking is commendable!
The R&D procces insight in your videos is just so freaking cool!
I can't wait for part 2! You should definitely do some testing at some interesting location with a camera on the plane.
I love how each project builds on each other
It is said that the rigidity between the nacelles is important for a side-by-side tiltrotor aircraft, but I was able to understand it well by watching the slow motion of this movie.
There are so many different moments that make the spar vibrate!
I'm hyped! Your approach to this project is awsome, and one can really see the learnings you've had throughout the years of making these projects. Really happy that you're sharing this with us, can't wait for part 2.
I am always impressed by your engeneering-skills. This rotor setup is just brilliant. Thanks for your videos, they are always a pleasure to watch!
I love how you explain such complicated concepts in a way that even I get it. Awesome job and I always look up to you for my own videos.
I actually recently did this in Trailmakers! Really unique challenge.
How
So excited to see where this goes it already looks great!
arguably the best example of the "engineering process." he finds a problem, fixes it. another one, fixes that too. and keeps fixing until he gets where he wants to be. ive never designed or made something and have it work right off the bat. it takes time but dont get discouraged.
The real hero here is the thermal camera. Those things are so darn useful when trying to find faulty components.
I love how you've merged together multiple project concepts into one. I was hoping to see the esc-controlled helicopter idea come back, and you didn't disappoint. Keep it up!
The moment with the rotor head was a terrifying example of why safety is paramount. Glad you're safe and whole after that
This was amazing. In 1984 I was in flight school at Fort Rucker, AL. One afternoon we were invited to the parade ground to view a flight demo of the Bell XV-15 tilt-rotor aircraft. To say we were mesmerized would be a colossal understatement. The aircraft was nothing short of spectacular. On the way back to the parking lot after the demo my wife heard one of the other wives talking to her friend say she wished he husband looked at her the way he had been looking at that aircraft. I am certain my wife sympathized. To this day I still walk outside when I hear a V-22 approaching. I anxiously await your completion of this project!
It blows my mind that you can get rid of all those complex mechanical components and replace them with software. Amazing!
Inquisitive, practical, creative, science oriented, fun, systematic and excellent explanations are just a few of the aspects that strike me in your projects. Thanks for sharing!
It is quite impressive the amount of research you do and your relentless will to achieve your projects. Very inspiring.
When you smacked the two helis on the ends of the V22 I instantly had to think of a compound helicopter like the X3, would love to see someone build and explain a model like that
This popped up on my recommended, and I must say, I'm addicted. I gonna watch more of your videos as they look interesting. Can't wait for part 2 to come out. the V-22 Osprey has to be my most favourite VTOL aircraft. definitely worth subscribing. Keep it up!
Dude. You never give up, do you? This looks like SO MUCH WORK!
Bro above me forgot to switch to the right RUclipsr scam account
Super awesome build. Can't wait to see what the finished product looks and acts!
Your helicopter video where you controlled pitch by varying the rotor speed is one of my favorite videos you have made. I am excited to see the rest of this build and it will be so cool to see your rotor head design used again.
your problem detection skills are unmatched!
I work on 22s for the marines and i can attest to how complicated these things are. They're flying transformers. I can't wait to see your final build!
Holy crap this looks amazing, I can't wait for the rest of the videos about it! Also, please don't get impaled by a flying rotor blade, there's over a million people that care about you Tom :)
You could try putting the wing spar in between the servo and the motor so the motor mounts aren't so long. Might help with stability but idk it was just a thought I had.
I used to work near a small airport, and on my lunch walk one day an Osprey passed back and forth over the runway for the whole hour. Was one of the cooler things I've ever seen. 😸
Awesome progress!! I REALLY wanna see someone build a 3d printed Channel wing that uses the dyson bladeless fan technology to have guaranteed airflow over the channelwing 😅 Its a design I've been working on but have no means of testing... Hope you can!
HI Tom, something that occurred to me is that you could use ceramic bearings. This are quite cheap and they come in big sizes these days. I bought some for a tilt rotor quad copter I was building.
Ceramic bearings are always better in performance and endurance. And the way the three bearings are each pressing on one point of each bearing lends itself to using a ceramic bearing and realizing the advantages thereof.
Here we go again. Tom on the cutting edge of flight control, low cost manufacturing and making it look easy.
As a long time RC & 3d printing enthusiast I've enjoyed all your videos, but this one is truly outstanding, the concept & execution are best described as "simply brilliant".
I'm a retired R&D engineer, and it is clear you have the most important trait inherent to that discipline....Tenacity.
I also enjoyed your recent video on using the slicers "vase mode" to print aircraft wings, that would possibly accelerate the 3DP of an EDF jet fuselage I'm designing/making.
Really looking forward to part 2, I'm sure the project will be a successful !
Frankly the best home science/engineering channel out there, you are doing a fantastic job of educating & encouraging young engineers.
I always thought these helicopters looked so cool. Great video.
Love your videos!! Keep up the good work!!
The videography is incredible! Those close-ups on the interface between the motor and the wings; really insightful!
I really really enjoy to see your progress on this and the way you explain and improve them.
Would love tosee more on this series!
Awesome progress Tom. Great walk thru on the process you are going thru. The lead / lag, set up on the rotors is crazy how effective it is being it is torque influenced. My question is "As fast as the rotors spin and as many changes per second are needed to make it do as you wish, how much does that effect the speed controller?". I would assume you use higher end esc's and have some sort of cooling going so they don't melt and let the magic smoke out?
I'd love tho see a parts list for some of these projects - those magnetic motor encoders look like fun! :D
Awesome work. The pitch control is mind boggling. Love your videos.
Can't you use the "cyclic control" for yaw control as well?
Also seeing this thing translate sideways would be looking awesome, especially with a fuselage!
Being an aerospace engineer as well, I highly admire your skills. Awesome job!
That rotor mechanism is genius
This is the type of content I appreciate on RUclips. Analytical thinking and factual information.
Thanks for posting.
I think you're gonna be a MAJOR innovator in the helicopter world! Keep up the good work. You should really try to copyright your design and introduce it to Sykorski or Boeing
His complaints about current ‘tilt rotor’ RCs are all spot on.
It's not his design. Take a look at the previous video on his channel, that he refers to.
Whoever's reading this, i pray that whatever you're going through gets better and whatever you're struggling with or worrying about is going to be fine and that everyone has a fantastic day! Amen
Thanks
another copy-paste scam comment..
Who are you
@@wojtekpolska1013 i understand that this is some copy paste bs but in what way is it a scam
I always love it when you show the failures, because in the end you succeed, but you had to overcome what must have been frustrating faults with completely unknown cause. So, you have to grind through and not give up, it's not easy even if you are knowledgeable and talented.
Awesome video Tom! Love the way you show the problem solving process.
Excellent video and subject once again Tom. Your ability to observe and use data to address the initial issues is truly impressive. I know how much time and effort goes into making the projects and editing the results, well impressed.
Amazing Tom!
Brilliant thinking and execution.
Can't wait to see the sequel.
Oh damn, congrats on 1 million subs!
Very, VERY well deserved Tom!
Hardware, software, components, balancing blades, building frames, design work... so much stuff packed into a short video, as usual lol. Nice work.
This Is genuinely amazing what you’ve achieved and engineered! And it’s great how you deliver and explain in to us all. Thank u Tom!
Building frames, control systems, and thinking afresh the way you do it is definitely impressive. I have built over a dozen different small UAV systems and this is indeed excellent work!
Another cracking project, Tom.
Amazing how you troubleshoot and iterate the prototype.
Have fun building the fuselage.
this is amazing and i cant wait to see it!
Man, you're mad smart but also so good at explaining it to the rest of us. Kudos
Tom, your videos are so well done! So awesome seeing how you solved for the complex motor system. Keep it up!
ingenious technique for pitch without linkage !! your videos go from strength to strength, found you during your air engine escapades and have been here ever since !
Amazing. Thanks for sharing the process.
4:40 great use of test rig and slo-mo
I admire your ideas and your implementation.
Please keep it up and show us your fails.
I am 60 years old and used to (30 years ago) build a lot of RC models. But today you have much better implementation options thanks to 3D printing, cheap milling machines and the many technical advances.
I admire and envy you.
It's impressive how you troubleshoot your own created problems. And how you create those totally-out-of-the-box-thinking projects. Creating blade control with inertia is just one mindblowing example... 😮😎👍
I am so glad you did this. I have been thinking of this since your first brushless pitch control video
Great video, if you add a vibration absorber on the shaft and motor, the entropy of vibration goes less. Thank you for sharing Pal
Dude, your development program is top notch. And the design is quite clever use of established principles & methods.
I have no words, Tom. You're a madman. Your animations are so extremely clear and well-executed as well.
This might be the most insightful use of foc I have seen to date in a hobby environment
very rare that i come back to a video to watch it full length again the next day. amazing
I finished watching the video and then realized that Part 2 wasn't out yet; now, I can't wait to see it released. Thank you for making such a Brilliant (I didn't mean to capitalize that, but I will be checking out that website too) and interesting video!
Working out that passive hinge. I've gotta rewatch this a few times. You blow past it kind of. Very cool. Extremely clever.
Nice Osprey. Thanks for sharing!
Showing how the helicopter blade pitches on one side in slow motion is so beautiful. It's borderline organic, it reminds me of a bird flapping it's wings. Helicopters are truly amazing contraptions. Your design is also super interesting.
It's super cool but I think it's probably causing the vibration. The torque reverses with every revolution, imagine how a car lurches forward when you let off the gas.
I don't see anything wrong with the tilt mechanism in the previous video, in fact I think it's cooler than the real osprey due to it's simplicity and the fact that it utilizes the same mechanism that tilts the rotors forward. I think forgoing any kind of traditional blade control is a really innovative way of building this kind of vehicle. Though maybe it wouldn't work for something the size of a real V22.. idk I'm uneducated
It's so satisfying to see good people with good tools. That CNC was an excellent investment, you've been able to do so much more with it.
Incredible work! This is a culmination of so much dedication.
Love watching your stuff Tom, your explanations are brilliant, l used to work at a well known aero and automotive uni ,so watching your stuff makes me miss being around this kind of MSc & PhD projects
,keep going dude!
your designs look so simple and elegant. Very fun, interesting and educational to watch.
you reinvented blade pitch control!! only goes to show how much of a genius you are! great content as always
Absolutely amazing. You are insanely talented and one of the most creative out there
I dont understand how we haven’t lost you and your videos to some crazy intense tech job at Lockheed or something, but I am happy your videos are still coming, this stuff is amazing
Controlling the rotorpitch in this way, should win you some sort of prize !! I hope you'll be rich soon. Its absolutely briliant!
My grandfather was lead engineer of the flight research program for the xv-15, the prototype of the v-22, and I wish he could see this video. Looking forward to this series!!
I'm impressed you can control the angle of attack without any additional motors.
This is great! I'm impressed the 3-blade version works so well.
YES! Been waiting for more content with the magical swashplate! Vtol is so sick. Great video as always Tom. Looking forward to part 2 :)
This is some seriously innovative stuff! Great to watch your personal progress!
Absolutely cracked lad! The projects you're getting up to are absolutely mindblowing even with all your previous projects.
My life needs Part 2 so badly.
The variable pitch mechanism is so simple that it's impressive.
So stoked! This is gonna be awesome!
