The flying "Heel Lift" - Arup S2 and S4 flying wings

[moya138]

He was not the inventor.

[squizzoo]

Don't worry, it will fly again. Everything these days is nothing more than a re-hash of old ideas. We have no new ideas, colleges have made sure everyone who graduates has no imagination or dreams. If you don't puke back what they feed you exactly, or question what they are forcing on you, they flunk you.

I told them what they wanted to hear and got my diploma. It was pure BS. What a joke.

The latest is the "new" helicopter being developed for the US Army which is a rehash of a 60's helicopter.

[GaijinNH]

Wow, I never knew these things had such nice flying characteristics...has anyone ever built a ultralight version? What did that one weigh, what was it powered with, and how many square feet of wing area did it have?

[oldfart387]

@GaijinNH Watch the video again. It said 780 pounds.

[GaijinNH]

@oldfart387 And at :42, there's a planform view, though it's hard to see the writing...  It's funny, the Easy Riser (the first official ultralight, and one I own) also served as an advertisement for a while.

[GaijinNH]

@GaijinNH 211 sq. ft., not much more than my hang glider, with a stall speed of 23 mph...think I'll try building a scale R/C...

[ibgoodok]

Can someone explain these measurements to me? I understand the length and span, but not the rest. I would like the other measurements in Ft/in and what they apply to. Thanks.

[wingnutwally]

I just love all of Bomberguy's videos!

[GerbilEssences]

Vought pancake resemblance?

[todetopandback]

Thanks for all the posts, especially the video. I am just tickled to see them. Cloyd Snyder was my grandfather. If anyone gets an ARUP up and flying I'd love to have a ride in one. My mom may have been up in one but I never have been. Silva talked a lot about the ARUP. Blessings, Amy Eisenhour SB

[TogieTung]

@todetopandback I have never heard of the ARUP plane before this, I thought the Flying Flapjack was the first to use this design but you grandfather was the first & wasn't even mentioned in the history books, I think it is very unfair to an innovative thinker such as your late grandfather.I think his design can be reborn as a UAV.

[ibgoodok]

@todetopandback Hello Amy, if you could provide any documentation or blueprints on the Arup, I will build the S-4 and be glad to take you up in it. I truly hope you or someone else does. Feel free to contact me anytime.

[LottoWinner999]

@ibgoodok I'll bet a good draftsmen with computer skills could come up with pretty accurate blueprint.

[LottoWinner999]

@ibgoodok Give me a ride and let me fly cuz I founf the US patent #2,062,148 assigned to Cloyd Snyder in 1937 for a variable wingform aircraft. A smaller 1p replica was built and flown c.1985 in Bristol IN. So all you have to do is get a copy because the patent has expired. Its wonderful economic airplane to build and its easy to fly!

[ibgoodok]

@LottoWinner999 LOL.... I've had that info for a while now. Thanks tho. It does help some however, it's mostly a description of the components.

[GaijinNH]

@LottoWinner999 A patent doesn't stop anyone from building something for their own use, only from selling things...

[WickedWillie45]

I remember the EAA's magazine "Sport Aviation" doing a very complete write up on these airplanes. Four models were produced.

[Jutte777]

Milt Hatfield built some replicas of the Arup called 'Little bird". Hatfield was a friend of Dr Snyders and I think actually could have flown the originals.The three 'Little Birds' built are owned by a guy who plans to rebuild one to flying condition.

The Arups were safe and flew well - Snyder even took his kids up in them.

[SLKA440]

Zimmerman knew of Doc Snyder's "Arups" and Richard Burton Johnson's "Uniplane" through his exposure to their patent applications, which were routed through NACA, where Zimmerman conducted research. The V-173 was inspired by this plane.

SK

[SixsevenBravo]

I would like to fly one of these

[ufoengines]

Too bad Dr. Zimmerman (who came up the V-173 Flying Pancake) and this guy didn't get together. I tried a cardboard model of this shape, and it didn't fly so hot. I must have missed something in building my model.

I've have this idea of using foam to "cast" an aiplane like they "cast" foam picinic coolers. The Arup S2 looks like the shape to try out this "foam cast and airplane'' idea with. If it works I'll YouTube the process for all the world to use.

[bnther36]

23mph stall speed for an 800lb airplane is pretty good! 37hp is a 1/2 VW...I wonder what it would weigh with a couple of layers of BID over some hot-wired foam?

More info on this plane would be appreciated.

[datzfast]

@bnther36 easy do some math

[ridedirtba]

LOL!!

[taofledermaus]

97 and 3/10ths MPH. I think if they pushed it, they could have gotten a couple more tenths of MPH out of her. lol

[tomterahedrob]

one can learn ALOT from the forgotten genius of the past and Bomberguys channel.

[2HEXJUMPER]

these aircraft are for sur the reason for UFOREPORTINGS

by people whom had not seen such planes before !

[altairian]

May I ask where can Blue prints of this aircraft be located?

I am interested on how hard it would be to make a mock up of one of those brilliant designs.

Pity it did not take off commercially.

To think about it logically if he was in Germany they would have been all over him with funds funny how the world works

[perwisky]

Well back then they probably didn't know as much about aircraft design as we do now. With such a large wing area, drag is increased as it is proportional to the area. Moreover, the wingspan (wingtip to wingtip length) to chord (length from the front of the wing to the rear) is small thus increasing induced drag. All this additional drag only increases fuel consumption. It is no wonder this concept never really 'took off'.

[datzfast]

@altairian might see a comeback with an electric version

[ibgoodok]

@altairian Were you ever able to find any Blue prints of this aircraft?

[altairian]

@ibgoodok nope still have not found any blueprints of the aircraft. I would love to make a model of one if I could get hold of some blueprints

[LuxorVan]

I wonder if there are any videos out there for any US defense weapons made by Bendix from South Bend, In? Like the Talos or other air to air weapons. Many people don't think about Indiana having any meaning to the world. History has something else to say because it isn't just corn coming from here!

[LuxorVan]

You can learn a little more about Arup co when transiting through South Bend Regional Airport. Plus you can even see an S model there! South Bend is a beautiful place well at least it can be. And like any city it does have its obvious problems. I was born and raised there and I guess back in the 1930's it was one of the great cities in America with Studebaker, South Bend Lathe and many others originating there. You could even say it was the next big industrialist city next to Detroit,Mi

[davidlee110]

that my hometown

[slrman]

Bomberguy, you Da man!

[GaijinNH]

A friend of mine owned one of these in NJ...it was in dire need of restoration, and had no engines or props...

[ibgoodok]

@GaijinNH Do you think he would be interested in selling it?

[GaijinNH]

@ibgoodok I haven't seen him in a couple of years, but if he still has it, he'd probably sell it. When I saw it, it had no engines or props & needed a full restoration...

[ibgoodok]

@GaijinNH I was under the impression that all four were eventually destroyed by fire.

[GaijinNH]

@ibgoodok Well, I saw the plane, and it didn't look to me like it had been in a fire, though it was in pretty bad shape. I myself was under the impression that there were at least 5 of them.

[ibgoodok]

@GaijinNH That's partly true. The S-1 or "Dirigiplane" was a glider with no engines. The S-2 came out in 1933 and seemed to get the most use. The S-3 came out in 1934 but was destroyed by an unsolved arson fire after its test flight. The S-4 was a slightly larger remake of the S-3. Raoul Hoffman, Dr. C.L. Snyder's engineer at Arup, left that company in 1933 and moved to Florida where he designed an "Arup-type" aircraft for a Chicago industrialist.

[ibgoodok]

@GaijinNH The Hoffman flying wing, Unfortunately, Hoffman's aircraft caught fire in

flight from a broken fuel line and crashed, killing the pilot. This may be the fifth one you mentioned, but it wasn't considered an Arup. I would like to see your friends Arup. Can you reach him or get pictures? Here's a newspaper clipping of one built later on. I don't believe it flew. Airport pictures show no cut-outs for Ailerons in the wing. ---

@GaijinNH

South Bend Regional to unveil historic display

05/15/2003

A full-size replica of a "flying wing" aircraft

designed in the 1930s by a South Bend podiatrist

turned aeronautical engineer goes on display

Friday at the South Bend Regional_Airport.

The two-seat replica of Cloyd Snyder's "Arup

Flying Wing" was assembled by retired engineer

Bernard Rice.

[ibgoodok]

@GaijinNH Snyder dreamed up his revolutionary aircraft design in the spring of 1926 after he threw a felt boot heel across a room and noticed that it flew quite well. Four versions of the plane were developed during the 1930s, but the Great Depression forced Snyder to abandon plans for a commercial 100- passenger model. All four Arup models were eventually destroyed by vandals. Rice reconstructed his model from photographs. It's 19 feet long with a 22-foot wingspan.

[fltgr]

Thank you, Bomberguy, for compiling and posting these film clips!

[skipjackbj]

23 mph landing? Almost STOL with out flaps.

[RoadRunnerLaser]

LOL... Ninety seven and THREE TENTHS miles per hour !!!

What a great little craft. I hope there are still a few of these flying about somewhere.

[denberg2]

Keep 'em coming Bomberguy!
