In-Flight Line Tension Research - Uncollapsible Paraglider Part 7 - BANDARRA

GroundHandling Online Course:
www.andrebanda...
I wanted to know more about line tension distribution in paragliders so I designed and built a custom system of sensors that is portable and can be used in flight.
It's arduino based and it look me a long time to make as I had no previous experience in complex electronics, PCB design or programming.
It was a great experience and I already have more ideas for the future.

Engineering is everywhere and it touches everything and everybody's life, so, good to see a class A engineer do his thing. I hope it inspires lots of young people to go into that direction. Because we don't need people that point out problems, we need people that find solutions!

[@Sky_Pony_1_mic_sierra]

This is the coolest thing on the whole internet right now.

[@AndreBandarra1]

ahahah :D

[@thedave7760]

@@AndreBandarra1 Makes me think, you could make a fully rigged VR paraglider simulator with actuators on the lines so you get all the feedback as if you were flying an actual wing.

[@SupernovaSpence]

The turbulance data is awesome!!! More data is going to be needed to prove it, but I think it's the first findings of what a potential pending collapse could look like! And it's so fascinating to see that with an experienced pilot, subtle cues indicate impending turbulance! It this kind of trend continues with collapses as well, then it should be easy to alert the pilot auditorily to a pending collapse situation so that they can fly themselves out of it, but more importantly, like your project is about, if no input is given, have a threshold or limit, to automatically prevent the collapse from occuring! So exciting to watch this project progress!

[@quinnmarsh]

This is seriously one of the coolest builds I've ever seen

[@CoIoneIPanic]

TENSEY MCTENSE FACE? im rolling. Seriously to see the circuit board and know i watched this guy start out with a simple sketch in video 1... Somebody said it before but this is the coolest thing on the internet.

[@jeremyransom7372]

I know absolutely nothing about circuit boards or electronics but was totally mesmerised watching you building it all. The first data is already extraordinary, so do keep the rig flying. And I just thought you were just a pretty face! Congratulations

[@neogator26]

When you said sensors I immediately thought "surely he has safety back ups". Exactly how I would have done it. This is amazing work.

[@NickSeee]

Andre you flipping genius. I am just into my second year paramotoring and came across your work thanks to a link from Tucker Gott - I wish you every success and whilst you continue to push the boundaries (having cracked sense and compute concepts) I really hope the wing manufacturers are beating your door down to work with you during their wing R&D phases. There are so many spin off benefits to what you have done. Thank you.

[@AndreBandarra1]

Thanks a lot dude, really appreciate it!

[@RodrigoPereira-fl5rx]

Que show parabéns André belo trabalho!!!!

[@JohnnyFaber]

Awesome work Andre! I loved watching the whole process. Also great job with the graphic illustrations. Everything from the scale design to the board layout and fabrication was so cool to see. The wing shaped, color coded 3d bar graph was ingenious 😁🤙 You sir are a legend!

[@AndreBandarra1]

It’s always a nice when people appreciate the little geeky details!

[@THE-APEX]

I suddenly find myself questioning everything I have done with my spare time throughout my life. Bravo Andre. I look forward to seeing the progressive transformation of your data into useful information, knowledge, wisdom and ultimately action. DIKWA. Epitomized. Is this your first patent? Congratulations.

[@engineer9528]

Awesome job, man! One more interesting thing to build and test would be an automatic reserve parachute launching system (ballistic for instance). That would respond way quicker than thrown by a pilot and powerfully enough to some chosen direction.

[@immortalsofar7977]

All this work/research deserves a published journal research paper. Write and submit one, Andre.

[@MarkLoves2Fly]

@Andre, Tracking the data at the malions is great, but what if you were to measure up at the wing? I think you might find some finer detail with many more sensors, all close to the wing connections. If these were all connected to your system via Bluetooth, or similar, you could avoid having too much drag induced by long electrical connections. Eventually this type of technology "Could" be used to make self correcting Paragliders. (Useful for landing unconscious pilots, who have been overzealous with their G-Forces. ) :D There is a lot of potential for the projects you are exploring. You are a true visionary of our sport.

[@RwP223]

Who is as excited as me? The idea is awesome!

[@seejjordan]

ME! This is SO awesome! Congrats Andre, brings so many great things together.

[@SupernovaSpence]

And meeee! It's really fascinating to see how we unconsciously get cued to upcoming turbulance and react before the turbulance hits. More data is going to be needed to prove it, but I think it's the first findings of what a potential pending collapse could look like!

[@alanrolland598]

Wow, what a project, well done with building all the hardware, software and getting it into something working displaying and recording. And thanks for sharing 👍. 👏

[@clauderousseau3305]

Woooooow! Andre, I had not looked at your videos for a couple of months, and came back to a highly professional site. Congratz. But that is not the most impressive. Passion of Leonardo, insights Of Musk, and IQ of ... I really don't know, man. THIS will be I'm sure part of every benchmarking process for paragliding design. The fact that you give it to the world is highly commendable. Thanks for the geeks that keep us safe. And stellar Kudos to you, Mr. André Bandarra!!!

[@asuccessfulsloth6203]

Wow you are very talented in what yo do! Im glad there's people like you to push this sport forward👍

[@MariaBethaniaCabrera]

This is the best invention since Penicillin :D. Bravo! You are a genius Andre. Also I can see how passionate you are about paragliding.

[@janismateuss]

Hoping for more videos with this! Would be interesting to see line tensions while winching, spiral dive, entering a thermal, stalling and other maneuvers.

[@AndreBandarra1]

My thoughts exactly

[@yosoylibre]

I am sure you are already improving the future of paragliders!

[@FlyDude]

I'm learning paragliding, more precise, PPG and KZbin keeps popping your videos. Happy to see you are proficient with engineering, by the way, your welding technique is perfect, it shows years of practice. Alas, the first thing went through my mind when I saw your approach with the sensors is that there was an easier and safer way to do it. Instead of cutting the lines - which forces you to add a security strap, just route the lines through a simple V shaped guide formed by 3 pins on a plate. Tension in the line would deform the plate and you can measure that. With the costs saved by not cutting and reassembling the lines, maybe you could have installed sensors on all lines.

[@gustavohenriquegueno4226]

I predict an autonomous paraglider quite soon based on your brilliant work! Machine learning and some actuators on the lines will fly it as smooth as a feather!! This will for sure bring safer gliders and push the sport forward! Amazing work, I can't wait to see where this will lead us all!!

[@transilvaniak8485]

I hope you get sponsored and achieve your goal man! This ambitious project and your complex bouquet of talents are worth it! God bless!

[@thomasrufer6206]

That is such a cool project! I dont fly myself, but as an electronics engineer i sat on the edge of my seat there! :) Well done, cool documented and a hell of a nice project. Congrats!

Dude! Mad respect for your passion for this project!!! I don't respect many, but you, you have my deepest!

[@MrTahitiSeb]

Absolutely Brilliant! Thanks to push the sport forward!

[@SteFly]

Wow that´s really a great idea! Perhaps you can also use it as an additional input for the variometer?

[@OkammakO]

Dude, just stumbled upon your channel. This is brilliant and you probably have a novel invention on your hands which you could patent and license. It's a fantastic idea and I encourage you to speak to a patent lawyer if you have any intention of commercialization. If not, keep on trucking! This is incredible. Subscribed.

[@AndreBandarra1]

That's awesome, thanks for the sub :)

[@alexpopovics3809]

I'm so lucky to be a beginner in the paragliding sport with inventors such as you! I dreamed of flying for decades since the very beginning Hang Gliding in the seventies. I just purchase all my gear and will start lessons soon. Keep on going on onwards and upwards!

[@SteveWrightNZ]

A good student pilot gadget would be a simple line tension unit that would speak up under certain unbalanced or low-tension conditions. This would be a very good groundhandling teacher, and an in-flight alarm for improperly executed manoevers.

[@kylewolfman]

This is so freaking cool. Paragliding and science. You cant go wrong! 🤘stay safe stay elevated 🙏🌄

[@flyblueskyguy5863]

Very interesting data and project. The summary in 16mins is very well done. It could have easily been a 120mins documentary for all the time and effort you put into Tensy. Very well done. Hopefully this can be used to improve safety. Thank you for your contribution towards this sport.

[@MatiasNombarasco]

man! I was trying to do exactly the same! but my roadblock where the sensors, glad you took the approach of doing them yourself! great video!!!

[@CuervoRC]

What an incredible project, those data are impressive, I'm sure they are very useful to paraglider and flight simulator designers.

[@breakthestrain]

Such an amazing project. I can’t wait to see how this keeps developing. At the very least helps us understand what happens when wings collapse!

[@kimhangbong]

brilliant!!! Measuring line tension throughout different states of flights. This is something I have been wondering but can not find the answer anywhere else. Keep up the good work!^^

[@MikeKing]

This is an amazing Andre, I hope manufacturers might want this kind of test data as well, as it can be amazing for their design specs, and of course, towards your uncollapsable goal. Amazing job with the end result and quality of the device(s).

[@HelpBuildABetterFuture]

Wow. Lovely and game changing work Andre, you've excelled yourself(again). Thank you for this and all your output. I've always wondered how the DHV and EN tests as well as wing review statements might be normalised for the particular pilot inputs, and compared. Also how safety performance and performance vs controls envelopes could be characterised in more objectve ways . Stadradised, automated and fully Instrumented testing follows naturally from combining this and your 'pilotless' project . In an ideal world a collaborative global R&D initiative would follow. Respect!

[@angelisfpv]

Cant wait till this becomes a full on product... such a genius idea.

[@NotRelevant1]

This is such a rad project! Can’t wait to see more data from more flights/conditions. I’d be really interested to see data from inside a thermal/various different maneuvers. Great work👍

[@markmcgoveran6811]

I love your work and it's very interesting. I don't think you will get a collapse proof wing with this approach in anything light enough to take off the ground. But you keep stumbling on the gold nugget and tripping over getting up and going away. If all you had were the load cells that you made and you had about four of those distributed on that wing you would be tuned into the wing way better so you could stay on top of it like when you hit that wake and you hit the brakes a little bit before you bottomed up because you felt that change if you were heating it you'd have been on it a little quicker

[@spartafly3014]

Hi Andre, you might want to look into ESP32 boards for the sensor pickup. You can avoid all the custom PCB and RJ45 stuff. The ESP comes with a LP core, wireless communication is on the boards and they would run on tiny batteries for a flight. All you would need to do is poll the load sensor and transmit to your hub ESP board.

[@AndreBandarra1]

yeah, I've thought about it but think will defo try esp32's in the future. For now have a tiny board and battery inside each sensor might be a bit too much and make the sensors too bulky.

[@spartafly3014]

@@AndreBandarra1 Just use a small lipo with 200ma. They are cheap, light and the whole electronics package should be 30x50x15mm and below 70gr. Price for the ESP board is below 10USD. The 200ma should last you an hour. ESP32 also offers you the LP core that is able to poll an input pin while in LP mode! So you go to LP and keep polling the sensor let's say 10 times a second, this way you might get away with 10ma/h consumption! You could ucollect the data, read out after flight and then syncronize the datasets. That would lead to a package of 30x40x10mm with a weight of about 50gr.

[@minonimo6479]

[@AndreBandarra1]

It's called lenght tuning I think, it's to make sure if you have a set of tracks and some are longer than others, this makes them all the same legth, which means same resistance and cleaner signals :)

I'm so impressed. Amazing work on the engineering. Not only does it produce useful data, all the components look amazing and well engineered. And good job on your first PCB. That's quite ambitious for a first one! :) I was wondering why you chose the rather large Due? There are lots of smaller, faster microcontrollers out there. :) And have you thought about making wireless sensors? ESP32's can be easily combined into a wireless mesh with the painlessMesh project. I have used it with succes in a LED project. Let me know if you're interested.

[@AndreBandarra1]

Thanks, appreciate it! Yeah the reason for the due was not knowing any better 😅. Every time I talk to electronics engineers I find 10things I could do better. Wireless ones are definitely on the cards, just need to find the time to develop it and learn

This is amazing, great job!

[@ddegn]

At 2:33 there's a set of four holes under the logo. The trace to pin #3 goes around pin #1. I can only guess this is a mistake. Besides double and triple checking the design yourself, It's a good idea to have other people look at your design. If you post images on one of many electronics forums, I'm sure you'd get a lot of good feedback. Good luck with your project.
