Why It Goes So Fast

[@davestevens7386]

I got this phone call from a guy looking for a prop for a 582, which I sold. He told me he needed a stock prop to break in the engine because the prop he had was designed for speeds over 200mph. I told him that he wasn't going to get a 582 to do 200mph. Little did I know, that was Mr Arnold.

[@stanRmeyer]

What a fascinating story!!!

[@maxvolume1037]

that prop is in my garage!

[@patman0250]

And little did we know you were full of crap. Seriously guy it's not about you and your fictitious story. Nice try though.

[@saraarnold571]

Michael used to sell his videos on DVD. When he was diagnosed with terminal cancer, he asked that they be posted on KZbin. He willingly gave them away to share as his legacy. So the copyright warning no longer applies. He passed away in October of 2015.

[@TRabbit1970]

An amazing teacher and a spectacular designer and builder. A true gift to those of us eager to learn how to design and build our own aircraft. Thank you to Mike’s family for gifting the world with his wonderful storytelling and instruction.

[@lrstaf6]

Amazing! You are what I call a natural engineer. If you don't know how to build something, you go get a book and learn how. That's how I went from a school boy to a senior engineer at a paper machine manufacturing company. It takes a little longer than going to a school, but it works, because you only study what you have a desire to learn. Thus, you work harder and dig deeper than you would if someone is trying to shove info at you. Congratulations on your record. Beautiful design and great quality workmanship on your airplane. You deserve that record.

[@vasili1207]

[@ThreenaddiesRexMegistus]

Brilliant how his instincts led him to almost accidentally make good design decisions. He genuinely seemed surprised to have these decisions validated by the various experts. Probably as good an example of function following form as we shall ever see. Genius!

Mike left us wondering what he would have designed beyond the AR-6. The AR-5 is at the Hiller Aviation Museum in San Carlos California (25 miles south of San Francisco). It hangs close enough, just above your head, to see it’s sleek and smooth lines. Makes you understand, more so, his thought process and application in building it. You must go see it in person, if you ever get a chance.

[@robertrainford301]

What a wonderful video, and to hear this selfless attitude about such great aeronautical topics is really encouraging! Thank you! Thank you!

[@tomemery1651]

I started watching these videos as kind of a whim. The techniques and hands on building got me hooked. This a truly amazing set of videos for anyone who has the slightest interest in aviation. Just shows what you can do if you study the text books and apply the information. I came away with a much better understanding of the dynamics of airflow and the reduction of drag. Godspeed buddy.

This gentleman was brilliant. What a shame he’s no longer with us. We lost a genius in aeronautical engineering field. Who knows what Michael might have cooked up had he lived. I’d have loved to have had the opportunity to talk to him. Wherever he is, I hope he is grinning ear to ear designing and flying his own speedy birds.

[@du4-fpv777]

Thanks to his wife for sharing all of these videos with the world. What a legacy. Did anybody catch what happened to the engine cowling? What caused the damage? He said he was going to come back to it but I never heard it. Feel like I waited 22 years to find out.

[@Luminaring]

He showed the cracked prop in the video

[@MrFlyingSquirl]

I don't know if you found out since, but in one of the other videos they talk about how the engine cut out(I think) and he had a low speed crash. It damages the prop, cowling and the wheels including the rear one. As far as I remember the rest of the plane was OK and he was uninjured apart from some bumps and bruses

[@theinterfaithshepherd9075]

Wow! What a pleasure to be able to watch a video like this. Mike is clearly a genius, there is absolutely no doubt at all. He 'says' he is not an Engineer, but he is far more than that. He could no doubt lead ANY aerospace program at ANY organization - although obviously his love is for subsonic non-military sport craft.

[@artysanmobile]

Michael must have been very satisfied to see the volumes and years of math and handwork result in such a successful record attempt. Aerodynamics and laminar flow are so complex, it must have been hard keeping the focus from start to finish. Mighty impressive. I have a single invention to my name, a somewhat complex design and complicated hand build system of high performance electronics, about 2 years of my life, to be proud of. From that I can relate to how profound it is to see all that work result in the intended goal.

I was an owner of a Midget Mustang powered by O-200 Continental. Laminar low wing and was dangerous in high speed stall when the boundary layer separated it was difficult to bring it out of stall.

[@slartybarfastb3648]

My main takeaway from this great video is that this airplane is likely what the best escort fighter of WW2 could have looked like had it been designed in 1942. Scaled up for fuel requirements, armament, retractable gear and powerplant but essentially solving most of the problems those war era designers encountered. Aesthetically, I think it looks like the perfect blend of Bearcat and Corsair if anyone ever hoped to do that.

[@saraarnold571]

Yes, his "little plane" as he so modestly called it, is on display at the Hiller Aviation Museum in Santa Clara, California. www.hiller.org/. It is listed as "Arnold 1992 AR-5 Sport Monoplane". My husband, David Arnold, Michael's brother, stumbled upon this plane at the museum one day. The two brothers were estranged. This discovery in part contributed to their reconnecting and re-finding family before each of them died in 2015 six months apart. David was a car guy--raced in SCCA, loved speed. They were both intuitive about machines though Michael delved deeper to become a self-taught engineer. David was so proud of Michael.

[@ricktssf]

an old 2 stroke motorcycles issue that is very similar to your exhaust gasses temperature increase ... when you ride a 2 Stoke motorcycle down a very long hill, the engine temps always go up! going down a long mountain, you could blow the engine... the 2 stroke uses oil in the gas to lube the engine. when "coasting" down a long hill the engine lacks the lube in the gas to keep things slippery and cool.

[@GaryL3803]

The old 2 stroke (1960s) Saabs had a freewheeling clutch to allow the engine to idle when decelerating. As a side effect, when the engine seized up, which it sometimes would do, it did not lock up the drive (front) wheels.

[@fredeagle8766]

keep polishing. a coat of wax would really sort out the boundary layer drag and flow. seal the smallest gap. prop blade root cuffs, no gap here too. go for mid wing at a dead right angle join at the roots. a rounded centre section goes with it, and apply small fillets as extra ! a strake or two may sort out local laminar flow break up, observe your wool tufts at all conjunctions. while where at it, get rid of the fuselage and empennage altogether

My college professor said it was difficult to establish laminar flow even in the labs. He talked about circulating different geometries through a laminar flow fluid and how how it is to visualize. The layers are very thin.

[@ronsoyka2555]

Very informative video. I wonder if it occurred to hi or any other viewers just how similar the lines are of this fuselage to those of a Corsair? I expected to hear he scaled down a Corsair fuselage. Long snout, canopy, line behind the canopy, empennage all very reminiscent of the Corsair. IMHO

When I first saw the unfinished AR5 I told him I thought it looked MEAN - He said it was the ultimate compliment - that just about all great fast airplanes look mean.

[@jolllyroger1]

I live very near here and when they say bugs they mean mosquitoes in mass ....I once drove truck from Orland to Sacramento about an hour and half drive had to stop 2 times to clean my windshield and the front of the truck looked fuzzy with mosquitoes wings you litterally could not see any paint or chrome the mirrors were the same .....I know the place they flew this and many of those people..... the smaller spinner makes the inlet similar to the inlet of a jet engine the prop acts as a compressor then the heating of the inlet air adds energy to that air which accelerates that air providing thrust or at the least limiting the reduction of that airflow either way reduces drag .... what do you think happens if you have engine exhaust exit pointing forward it's simple logic

[@JamesSmith-op7yc]

Oh goodness, Florida "Mayflies"! Just turn you green when you're riding your motorcycle to work. I so appreciate and admire Mike Arnold and his work. Truly outstanding engineering and and passion.

[@DoctorShocktor]

A quick aside, it would be great if you would provide a full description, such as the gentleman’s full name, the aircraft name, the achievement, the video’s source, who posted it, and any other significant details etc. to explain why this video is important and posted on KZbin. I didn’t even know what the guy’s name was until digging around a bit. Historical video postings also need historical text support in the description.

[@alestursic961]

What a wonderful achievement.

[@iforce2d]

47:28 I don't see how this explains why the drag reduces as the wing is moved further back, because there would be a 'nozzle' at any position behind that as well. Isn't the peak drag at the middle (widest point) simply caused by that being the point of fastest airflow?

[@Luminaring]

Peak vacuum is at at the middle. He explains it well in the beginning of that explanation.

Shawn Raymond is correct. Also consider speed or racing is the goal. The physics of racing are of primary interest. This isn't the devevelopment of a cargo plane. Lift is not going to win a race. On a rocket or missile, where speed is of primary concerns then wings are mounted in the rear, where they also become spoilers reducing unfavorable air.

[@unclejack123]

Beautiful little A/C ...Well done .... Ques: have you ever run the numbers on using either of the Rotax Radials in your airplane?.... I think the 5 cyl. version is a close fit already ....... The 7 cyl. is under 36" wide wide ..... JRW

So happy for him, as always a 👍

[@MrJdsenior]

If you want a REALLY GOOD (IMHO) nuts and bolts review of interference drag, relating it to divergent parasitic nozzles, the middle to later in this video is GREAT! Really improved my understanding on a practical level anyway, mostly Horner oriented. I don't think it's the entire story, as the aero expert points out later, but great insight. When I heard him say 38 HP, my jaw kind of dropped, given those speed numbers and time frame. NICE! This is a must see for aviation nuts, should have many more views. "It was very easy"...har har. Looks like you guys got some good support on the attempt, officials wise. Airplane communities, aren't they great? HEY, My 84 SE! Looked again, not the "5 letter" (wrong wheels), but close, one of the two years before, if I remember correctly. Well, not MINE, exactly, but mine was a great car, smooth and fairly peppy. Then it got transformed into a bit more of a fire breather with a Rotary Engineering Turbo Alternative, and some fairly serious suspension mods.
