😂😂😂😂 I busted up on this 😂 thanks for the laugh. Your the best

Ha ha. Great coment. Cheers from Argentina.

Roflmao....now that's funny right there !

this has got to be a tee shirt its great

Holy Crap I laughed like hell at this. Mike! This needs to be a new T-Shirt!

ha, beat me to it .the guys from mini draco are all heading to russian salt mines .. for a rest ..

LMAO I had the same thought.

HAHAHAHHA YAH

😆

Sure has a lot of small bits to fabricate. You'd need an army of 3d printers to have one built in a reasonable time.

Lol yeah! And it's still called "Scrappy" lol 🤣

Mike keeps saying "Back to work" but I think he spells it P-L-A-Y, just sayin 8)

variable wing geometry has been known for many years. It's nothing new, ok the materials are much better now but the idea itself is very old.

@@bigdevil73 Yes. The theory has been around for a long time. But no one has built a practical example, on a flyable airplane, with as much geometry change (dual slats, camber and chord) and with as simple and efficient mechanism as part of the design.

I know, me too! He and his skills are nothing short of amazing to me!

100%, incredible design mind.

Same here. I just get blown away more and more. True genius. Let's go!!!

You know, you say he's on another level, and I'm not sure that's exactly true. What he is, above everything else, is free to build it the way he wants to. Others can't do that because they're constrained by corporate limitations, time, money, or, yes, even education and knowledge. I'm sure that there are other engineers out there who said 'Oh, I could have done that, IF my company would have let me.' Mike doesn't have that problem.

I think he impressed himself this time.

Just live stream the whole workshop / hanger 24/7

Can we get the directors cut

SR-71 don't give him ideas.....

I flew the SR-71 and the engineering and innovation going into Scrappy is on a similar level.

Also this guy with about 7 minutes of flying experience is speechless.

Howard did flush rivets for the movie 🎥 Hell's Angeles

You should go interview him for your channel when this is done.

Holy cow this is actually a living bird 🦅

YES! Give it up Mike! 😆

Snyder cut please!

Soon

Ya, true, this shows us what you can do when no one says, “you can’t do that.” And you work on your own.

Welcome to desktop aerospace

Better wait to see if it flies first!

He's relying on hundreds of engineers who wrote the CFD software. Hopefully they got it right

@@jg809 CFD makes use several assumptions which we know to be incorrect. We do experiments, observe results and introduce constants into the equations to get around the issue but, those constants really only apply for the cases we test and thus surprises are always around the corner if there are 'unknown' "unknowns" involved in one's particular case for which CFD is being applied.

To be fair, as a fellow GT grad, those profs aren't really there to teach you, more to just test you. They leave the teaching up to the students, lol.

Yes! Laminar flow FTW!!

You need to have Destin on.

Haha Destin would be gleeful! I bet the flow is not laminar but is attached turbulent flow instead. Very few wings keep flow laminar that far back, even with boundary layer suction devices at low angles of attack. I know what Mike means though! He probably means “attached” when saying “laminar”.

Yeah i'm not sure laminar is the right word here. Yes the air is remaining laminated to the wing.. but as you may know laminar flow is something very different that I doubt often happens on a wing.. though maybe I'm wrong.

@@Lithoushine Thanks captain buzz killington.

I'll take hour long or more videos from Mike any time!

Give us the 3 hours Version, please! Plus 2h bonus material maybe?

I will watch the hole 100 hours about this wing. I knew it would be trick.

Just have a 24/7 live feed.

Yes, I’m saying it. Short intros like this followed by a deep dive. But I’m repeating Patey…

haha!

Straight after the frame was modified

Do it! I’m 55 and just passed my checkride and got my license. It’s the best thing ever!

@@RogerWyatt I'm 58, Passed my check ride last October. Do it!

@@frankq2 love it! Starting my tailwheel next week.

Glad you enjoyed it!

Yeah Draco was nuts in so many ways but Scrappy is truly an engineering testbed. Great engineers try to steal Newton’s lunch money!

Wow... you're a fan of Mike, too?

Welcome back my friend 👍🏻🤠 thanks as always for your fun comments.

@@MikePatey ​ - wow, slats on top of slats - it's like telescoping slats... It's telescopes all the way down...

LPL is here?! Always knew he was a man of taste

That's allot of chips!

The 109 had something similar.

thats..... wow super accurate

You can't forget the Carbon Fiber Clippings from the whole body of the plane.

@@saulekaravirs6585 oh wow ….. how could I forget all that scrap carbon fiber clippings or how about the scrap sheet aluminum and wood to make all the molds.

Honestly if this works well he could be making history.

@@RespectableRSYt Exactly. The second I saw those double slats I knew this was gonna be a game changer for the experimental aviation, and probably aviation in general...

i was thinking the exact same thing!

That's the next phase. CNC cut feathers.

Oh man, I’m sorry for your loss! That’s a tough one!

Oh no, I am so sorry. My deepest condolences to you and your family. I wish he could’ve seen it all come together. Sending love and best wishes.

Thanks everyone. My Dad had MS and fought hard for a long time and was amazingly upbeat most of the time. I should have actually started this by saying “Thank you” to the Patey’s as this is a channel my dad and I would watch together and talk and debate the possibilities of what was coming next or how awesome what we had just seen was. He was a Vietnam era Army pilot who flew Beavers, Bird dogs, Mohawks, and Helicopters during that career.

Single, dual and triple slat wings have been attempted since 1918. The first single slat design by Gustav Lachman patent was rejected because the German Patent office didn't think it would work as intended!! Many early designs failed to withstand pressure loads. When high velocity wind tunnels became available in the late 1930s engineers soon determined the causes. Even so, Handley Page developed an effective slat design the following year in the United Kingdom in 1919 and was patented with Lachman. Leading edge Kruger flaps designed in 1943 in Germany operate with an almost identical aerodynamic airflow concept as extended slats but reduced drag at very low airspeeds. 25 years later, testing on swept wing aircraft designed for high speed flight, the Kruger design was reintroduced on the B-727. An update to the original design was attempted with drop down slat from above while a second, a Kruger flap, extended from below and farther forward. It was not advanced beyond a wind tunnel test because of laminar airflow sensitivity. A single Kruger flap by itself was incredibly effective and implemented on the B-747. In my opinion, I agree with your comment, Patey's design would qualify for a patent based on his specific straight wing design because its design is specific for very low speed flight parameters. It would be interesting to see the airflow analysis for a wing designed for 200 to 250+ knots but can leverage a landing airspeed of 100 knots or lower, which could reduce runway requirements of single aisle regional airliner turboprops like the De Havilland Twin Otter or Dash 8 Q400. The reality however is different. Rural airports worldwide can handle DHC-3 / 6 / 8 easily. The demand for extreme STOL performance has almost disappeared - even up north in the famous bush country. But it would be very cool if a DHC-6 fully loaded could take off / land at max weight of 12,500 lbs at 90 knots and 550 - 650 feet of runway and clear a 50' obstacle!! (currently capable of 1,200' takeoff / 1,050' landing) with such a slat / flap configuration.

@@DougHanchard Wow, interesting. Thanks for the info! You're right that the market may not be there for his specific design, so it may not make financial sense. Regardless, it's interesting to know that people have been trying similar things for so long.

This will lead to high altitude helicopter rescue blades. Mark my words.

They would all want to have their say

He puts up his own money and he only needs to convince himself for new ideas. A room full of engineers for a company has so many levels of hurdles to jump through before something can reach the blue print. But yes, Mike is phenomenal at what he does and that is why he is very succesfull and have a formula car even mounted in his hangar as art piece :) The man has no limits, well maybe some real world limits. He also work on scrappy in his spare time. Well, I assume he can dictate his spare time alot more these times but still, achieving this on nights and weekends and some extra "spare time" during company hours it's just insane!

Good to see you over here! You’re seeing some amazing engineering in progress!

Up you got with this comment, its absolutely true

I mean he did anodize those internal parts that no one is going to see once its assembled

Like......what?!?!

@@charlesballiet7074 I believe anodizing aluminium prevent it from corroding and becoming all covered in white corrosion powder.. Or its straight show off

Person? I don't understand your comment. You don't actually believe Mike is human do you?

Mike is the Howard Hughes of our time.

Not to take anything away from Mike but many of the great aero engineer's didn't have computers, CNC machine's and solid works and air flow programs to work with. How long would it take one engineer to make the same analysis with a slide rule? Not to mention the machined parts would not have been feasible before modern CNC maching

@@AtlasLathe That’s true but also not a fair comparison. How great would Mozart have been if he’d had an electric guitar?

And money

@@clarenceweaver6681 so much money

Money buys the equipment to make the parts. It also buys the software to do the design work. I appreciate the concept but I think there's a whole engineering department to support him, not that that's a bad thing. You can't do all that work on your own When you have that many resources at your disposal no one else can come close in a STOL competition

Well said @Dankoneon

@@easternwoods4378 There’s always that guy, and today it’s you. Haters gonna hate… 😢

Same! Do you know what fea software he is usimg for flow analysis? Looks like solidworks for the solid modeling.

@@YourUncle8501 No idea, I've never used CFD software. I only know a little about the math that makes it work. I'm just in awe of what a skilled operator/tech/engineer can do with software when they know how it works and have an idea.

Would you know what CFD software he used?

The cool thing about modern MCAD software is you almost don't need to know kinematics and all the e^(i*theta) stuff :)

Lol!

The u-2 could probably fly on mars if the atmosphere had enough oxygen

Hold my WD-40 Now that is funny

Good one!

@@purplepenguin43 I seriously doubt it. U2 can’t get to 100,000 feet, which is what you would need to get the same density as Mars.

Seems like the scrap theme went out the window a while ago doesnt it

with all the machining that went into the billet there is only a scrap left...

Bill it!!

@@tbled52 yup. Scrappy in name only now.

Can't stop thinking of the Aliens second mouth seen for some reason when I see those double slats move. Lol

Funny you should mention that, he commented on the video!

Would be a great promo, not that Mike should need it.

Just call Scotty and beam down some transparent aluminum… or sic Patey on the problem and get it DONE!

This

@@Mrfishlou lol you beat me to it!! Nice

He is gonna rebuild draco, think how scary draco 2 is gonna be

I thought he was going to make it simple... I didn't understand Mike Patey.

@@The_Professional_Hobbiest honestly can't wait for the new Draco, I was genuinely shocked when I saw the thumbnail from the crash video! But gladly everyone walked away, and the new one is sure to be better than ever knowing Mike!

Me too, was waiting for some Saturday morning Scrappy. Worth the wait!

I was wondering the same thing. What could he do for an F1 team? Btw, 2021 has been a great season.

@@thomasmonachino2038 Yeah that honda engine has come alive this year, McLaren coming together, Merc sandbagging lol.

TFW your carbon fuselage, NASA control room for a cockpit, slammed suspension and sprayed 8-banger are the _least_ impressive parts of your airplane.

Lol I was going to say that

Hey now. I think maybe the tube used for the joystick is from a used plane.

Jeff glad to see you on here mate lol.

Love the channel bro! 🤙

no no your alfa is crazy enough

Next build - My Lamborghini powered Homebuilt Airplane!

Totally agree...watching Mike's thought process is what I really enjoy, and believe it can be applied to our own interests and developments, with whatever we are doing, in a very positive way.

Should really have Destin visit the hangar!

Unfortunately I think mike means attached not laminar. High lift with a drag device in front of a slat (the first slat almost 100% does nothing positive aerodynamically but at least it will increase the wing area). I’d be extremely surprised if the flow is laminar through both of those. Plus who cares about laminar flow at low speeds, profile drag doesn’t dominate there. He also probably wants the flow to be turbulent so the boundary layer stays attached.

@@lenmetkowski9899 You obviously watched the video but understood nothing. Laminar flow IS airflow attached to the wing. The leading slat, and all slats aren’t designed to be laminar but create and extend laminar flow over the wing.

@@lenmetkowski9899 I’m guessing you’re not an aeronautical engineer. Might want to use that Google search and look up how wings create lift vs how they stall. I also double checked my knowledge of laminar flow with Wikipedia definition and Mike’s description with words and graphs are pretty consistent. As far at whether the leading edge will be effective or ineffective to the flight of Scrappy that’s a discussion you want to have with Mike, pretty sure he doesn’t need my help defending his decision, besides what the hell do I know about airplanes I’m just a dumb helicopter driver.

@@king-o-vetts9899 Laminar flow is smooth layered flow. Laminar is from Latin meaning layers, it has nothing to do with attachment to the surface. You can have laminar flow that is not attached. Laminar separation bubbles are phenomena where the flow separates laminarly then re-attaches after it transitions in a free shear layer.. It normally occurs at low Reynolds numbers when an adverse pressure gradient induces separation.

Nah, they would ruin it

Funny that people still think TV matters.

I see it simular to building something for the military. They got the budget for it.

Bruh... Just, no.

Nah man, if anybody could interrupt Mike's stride, it'd be them. Let's not have that.

Calling this project Scrappy is like calling a fat man tiny.

Thanks Elliot 👍🤠. I’m Just grabbing a snack and back to work and your message was near the top of my resents on my screen. Great timing. Aviation is such a small and amazing family, i hope your going to Oshkosh, if so, I’ll see you there my friend.
