I Just Broke My Airplane Wing - What I Learned | Scrappy #47

I put my wing spar design to the test. After designing and extruding my own custom aluminum, I finally get to test it...to the breaking point. Watch as I put all the engineering to the test!

Hi Mike, love the wing spar testing. Like most beams if they don't suffer catastrophic failure due to fracture they fail under buckling. If would be a fun test to add a spar (shelf bracket) at the point of buckling. It should move the point of failure outboard. Maybe you could add another 200lbs to the load, pointless but fun to break a few more of those spars. Back to work...Tim

Can' they use carbon fibre spars

[@alexanderunguez9633]

@@michaelmcneil4168 FEM and classic analysis work really well with metals but analysis on carbon fiber is incredibly complex and is still not very well understood. The other drawback of carbonfiber is that it's not very flexible. You can push metal past it's loading point in a pinch without a catastrophic fracture, but composites tend to shatter. This is why designers tend to pick metals for load bearing structure parts and composites for low risk parts.

Well Done, Professor. My Wife is a HS Math Teacher of 30 years. I have often given her Hot Rod publications to see how the math applies to auto motorsport. These aviation projects, Draco and Scrappy, provide a much wider example of applied sciences. My Daughter also teaches. She is involved in a "Project Based Learning" program that the HS Students find a need then design/create a solution, prototype and build, then market. I think that the 2 projects are worth creating a chronologically ordered VLog to use as a Teaching Tool. I think, Your Work on both Aircraft, would answer many questions the kids ask..... 'Why do I need all of this math ?', etc.

But, students WOULD want that detail. I'm pretty sure that Mike could easily spend 8-10 hours going over the design criteria of this spar and it's design just in Solidworks. Most people watching this channel would, by the end of it, be bored to death, but students would benefit greatly..

You don't need to be an engineer to understand or relate to building planes. Hobbyists do it all the time. Sometimes it's harder for the hobbyist as most designs don't scale down very well. Yes, Mike is one of a kind but many people can relate to perfection.

Definitely a valuable resource to the public. This is what it looks like to simply work the plain process of developing a complicated thing that works well.

It masks the elegance, beauty and joy of it.

The builder changed up the rib spacing from the plans in order to add a slightly larger fuel tank, although he kept the compression struts located according to plan. Maybe not enough to make a difference, maybe it would. But the engineers at Piper who designed the PA-14, which the 2+2 is basically a copy of, put them where they are for a reason. I'll trust with the number of 14's still flying around in the bush, that they got it right. Keep the videos with the explanations coming.. I'll keep coming back to watch!

I would think Carbon Fibre tends to snap rather than deform in one piece

[@Nic-te3vq]

Most likely because carbon fiber is stiff so it’s failure point would be catastrophic versus aluminum which can deflect and return and any failure is not your wing snapping into half

[@chrisruf7590]

Many sailpanes and acrobatic planes have very strong Carbon fiber spars. +/-10 g or better in some cases

[@dannyt2885]

Another grand slam Mike, I love geeking out on the technical aspects of building airplanes, the crazy part is I've never flown in one! Thankyou for taking the time to make and share these videos with us. It's getting close, Scrappy is getting his wings and I'm getting excited!

[@paulabbott3601]

In episode #48, Mike is fitting the equipment for his anti-G suit

[@williamlyle8265]

Just purchased a set for my son's 11th birthday. He has been loving every minute of this build.

[@matthewsellers82]

Talking to a professor at a major university, he was telling me he has a really hard time persuading many of his students that at some point they have to get away from their computers and actually build, test and verify.

[@v1rotait23]

Build, but that would mean getting off their computers and devices, getting out of their chair, room, basement, classroom, and lab and get dirty hands, and having to use a ruler, pencil, scriber, drills, drill-press, overalls, safety glasses, ear defenders, punches, drifts, hand and machine hacksaws, deburrer tools, ratchet tools, grind stones, grinders, mig/tig oxy, arc and spot welders, lathes, machining, sheet-metal skills and shears, mills and milling, cutting fluid, rivet guns, rivets, bolts, nuts, compressed air tools, socket sets, surface/depth gauges, levels, chain blocks, winches, hoists, hydraulic presses, hand cleaner, learn to polish your safety boots... What have I missed out?! ah, a floor broom, hand brush and pan and waste bin to sweep out the workshop after cleaning up! :)

[@earthsciteach]

The worst thing about being an engineer is being stuck behind a computer!

[@fmh357]

What I love the most in your videos is the kindred spirit in building what you design. A real Maker or Creator if you please. Keep it up Brother. God Bless you as well. Draco was a real monster of an airplane and Scrappy is just plain insane. Thanks for the fun.

[@geoffmeadows619]

Been up since 6 to watch this video! Thank you for all you do Mike!

[@Gunnie1961]

Awesome design and testing there Mike. You bring innovative designs to the table and test them to their breaking point. Scrappy is going to be a flying tank of the bush plane ranks.

[@mcminimethec]

If Mike was my neighbor, I'd be over at his place as much as possible doing anything I could to help out.

[@jayfisher5559]

I mostly want to thank you for the videos and letting me see who you are. An example of what is possible when a person can live without guilt and fear running the show. I am not there, but I really appreciate the example you and your family set for those of us who struggle with success in life. I would love to have a part of Scrappy as a touchstone for my shop. I will be happy to send the fifty dollars. Be well, Jay

[@OMG_No_Way]

When Scrappy is parked at Oshkosh next year and has a Carbon Cub hanging off each wingtip, it’ll definitely be a crowd gathering display.

[@snoopy7647]

OSH AirVenture 2021, with a Carbon Cub hanging off of each wing! Don't forget about the possibility of hammocks, either! Mike and Mark Patey, two extraordinarily intelligent and gifted individuals! Both are very giving towards the Aviation Community, with all that I've watched over the last few years! Keep up the great works, guys!

[@secondchancesurvival]

Up next, Mike is going to make 2 mini cubs to launch from his wing tips like drone versions of drop tanks!

[@woodywoodward9624]

Congratulations Mike!! What a demonstration of faith, hope, Love, Joy, inspiration, and perspiration! Your public must have let out a breath of collective relief! Now we can look forward.to watching the wings become reality and then “It’s Alive!”

[@dmccollom1969]

Just how did you get that corneal abrasion? Ron threw safety glasses in my eye...

[@klesmer]

Thanks Mike. This is one of the most informative videos I have seen in a long time. I never would have thought an extruded aluminum spar could be that strong. Being a lifetime fan of Bellanca's wooden wing wonders it would be interesting to see what their wood version of your spare would look like. Probably alot like the Viking spar I think. Looking forward to seeing the wing construction videos.

[@rconger24]

Mike seriously you should set up a bleacher section in your hanger and just sell tickets for the Draco giveaway fund.

[@ILLEagle_1]

Thanks a ton for not having mid roll ads on your videos!

[@budrohammbone2806]

Oh Yeah, Don't forget the hammock anchor points on both sides of Scrappy !

[@ManicSalamander]

OOOOOHHHHHH! DO IT! DO IT! DO IT! :)

[@deanmiles3505]

Hi Mike, It's so much fun to watch testing of material. I was in the Marines back in the 80's were we went to a webbing material manufacturer as part of my training for flight equipment / parachute rigger. We got to see them test pilot harness and parachute webbing to failure. It sounds like a gun going off when it breaks. Take care, Be safe

[@keepitsimpleengineer]

"One physical test is worth more than a thousand expert opinions" 🤔

[@davidrobins4025]

Amazing engineering for Scrappy. Thanks for giving us some insight into how you develop the parts you use in making Scrappy. And, of course, thank youo for taking the time to do the videos you are sharing with us. You have truly opened a whole world of general aviation most of us knew nothing about.

[@cunhafixit]

I should be preparing for camping with beavers, but Mike posted a video.

[@MikePatey]

😂🤠

[@edwardhasiak7961]

I was ready to go for a bike ride. LOL

[@acirinelli]

I was supposed to be working in the yard. Wife: “that’s a long one today” ... yea 40 mins! See ya in a bit lol

[@wb6anp]

I was supposed to be building my wing but his video popped up.

[@gwbuilder5779]

When I was a kid I thought about things like this, but the adults said I didn't understand. I'm glad you are going beyond the impossible and proving the phenomenal. Thank you for sharing your knowledge Mike, you are a true man of integrity. Your weight to capacity ratios are fascinating.

[@Big_Nipper]

1st, for the first of the wing build videos I've been waiting months for....bahahaha. Can't wait to see what Master Mike is going to do.

[@dalemllns]

I've been watching this project a while. Anxious to see first flight. Awesome plans. Rooting for Scrappy.

[@daviddale3624]

Nothing makes an engineer happier than a "validated" model.

[@thebigskysky]

Mike, your videos are always a joy to watch. I cant help but think you would just go crazy talking with my old Aerodynamics professor. Have you ever considered taking on a senior project, possibly for the Best Tugs work or even to design some crazy idea that you havent had the time to put towards yet? Your drive would certainly inspire new engineers.
