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.

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.

Mike, Don Miller and I worked on this same design FIFTY YEARS AGO in Anchorage Ak. We didn't finish it because we were doing it with imagination, and didn't have the math to prove the double slats, but Don did get a STC for extended wings and flaps, and vortex generators on the wing tops, and I told him I thought the VG S were upside down, which was true. THE THING NOBODY HAS GOTTEN RIGHT YET IS YOU NEED TO MAKE THE FLAPS FULL SPAN, AND MAKE THE WING TIPS SLATTED, WITH FIVE FEATHER LIKE FINGERS THAT ROTATE AND FLEX UPWARD LIKE A EAGLE OR CONDOR WING TIPS. THIS FLEX WOULD ALSO GENERATE MORE LANINAR FLOW OFF THE TIPS AND PRODUCE A CLEAN HORIZONTAL TORNADO LATERAL FLOW OFF THE WING, INTO THE DOWNWIND WAKE. Richard Kinser. I think Don's STC is still in the records. It was originally for a PA14. HE WAS A RETIRED FAA STC OFFICER.

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.

[@king-o-vetts9899]

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.

[@lenmetkowski9899]

@@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.

[@nathanielclark8725]

I like that all the slats are synced together as they are. I work on G150s and the slats are actuated via ballscrew actuators and are connected to each other and spun via a flexible driveshafts. It is very common for the actuators to get a couple degrees off each other and cause a slat failure. So the fact that Scrappys slats are engineered the way they are is good engineering

I have to say I just watched the video for the second time and the more it sets in my mind the more I realize how genius and beautiful this design is. In 2 months I will be starting my freshman year of college studying Aeronautical Engineering. Your videos are truly inspirational. Every time you come out with a new video I get a spark of excitement and it makes me all the more excited to study hard and pursues career in an aerospace field. By creating and sharing your designs your not only Building Scrappy but also you are building excitement in the next generation of engineers like me.

I'm not even into aviation but I'm so addicted to this build series. The engineering is incredible!

[@terrybeemer4444]

Mike I'm very impressed with the engineering rigor you invested into your wing design to include your automation adjustment scheme so not to overload the pilot's tasks during the various critical flight states (takeoff, landing, etc). Earlier when your post discussed your wing concept I visualized a more standard slat concept I was blown away with your final approach. In my humble opinion, Scrappy may very well outperform DRACO especially in the STOL competitions. Sir have a great day

[@andrewfalenski6583]

A recommendation: When your wings are clean (slats and flaps retracted), the paint colors are normal. When your slats and flaps are extended, have the newly exposed surface area painted flourescent lime green (emergency green) or flourescent international orange (emergency orange) so that people on the ground, in the air, from inside Scrappy, etcetera, can see when the wings are in a dirty configuration. I also hope you have patented this design.

[@jonasbaine3538]

I wouldn’t be surprised if he released the plans without a patent for open source usage to accelerate other designers innovation.

[@seq165432]

Way back when (40's) Stintson built a very similar wing for a R985 powered monoplane with extraordinary STOL characteristics.

[@alexchappell7050]

Westland built a wing along these lines in the 1930s...

Your Wings are more engineered than the stock Cub itself :)

[@ryanmcgowan3061]

The stock Cub never had FEA and Fluid Dynamics. These wings are probably more engineered than Saturn V.

I'd bet it's got more engineering in it than most of the GAA flying today, at least model simulations. Computers can do more simulation in a day than an engineering team can do in a year. Just have to beware of GIGO.

[@LanceT.]

As a patent attorney, I was sitting here hoping that you've filed a patent application on this design. It looks very exciting!

[@DougHanchard]

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.

[@LanceT.]

@@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.

[@michaelbochenski6299]

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

[@Rdhog]

Private pilot here with a fascination for mechanical engineering. If I am understanding the abilities of this wing, in the slow flight mode, you will have a fully controllable aircraft at an AOA that is so high that the plane will be descending yet not stalled. In effect having a built in stall/spin proof design since to stall it the AOA would have to be well beyond the point of supporting the aircraft. Amazing. Can't wait to see the detailed video of how you designed this.
