ARUP 2, 3, 4 & 5 - Semi Circular Aircraft Prototypes By Designer C.L. Snyder MD From The Early 1930s

For more information, please visit "www.luftwaffeaviationhistory.com"
A series of photos of the very rare seldom seen semi- circular wing flying machine known as the ARUP (and combination of the word AiR-Up)and designed by C.L. Snyder, MD beginning in the late 1920s and early 1930s. One of the earlier models featured a tricyle land gear...one of the first such landing arrangements in the world. Raoul Hoffman, Snyder's collegue from the very beginning in the late 1920s, died in 1934 of TB in Florida. Glenn Doolittle, the cousin of the famous Jimmy Doolittle of WW2, was his test pilot. Another colleague in the ARUP program was Ralph R. Gracichen, designer of the worldl famousFord Tri-Motor. An entirely different plan form of the all-metal single wing famous tri-motored civilian tranport. How this come about in unknown. Neither Hoffman nor Snyder completed any of Hoffamn's several new circular designs..one a twin engin. On the other hand, they is a mystery here. Some one or some people wanted to destroy Dr Snyder's company and deam. It happen through arson coupled with vandlism Plus The Great Depression doomed all the investors inl five prototypes of this semi-circular wing
concept. Highlights included the ARUP #2 photographed as flyng over Washington's Capital Hill. Dr Snyder gave up after the arson and valdism...turning his back on the so-called "flying heel" and walking way forever and out of aviation history. Other Americans would try later circluarl wing designs such as Charles Zimmerman and Chance Voight completing their successful "flying pancake...even little known late-comer Arthur Sack in late 1944-1945 Nazi Germany. His Sack As V-6 was a total design failure. C.L. Snyder MD died in 1971. It is still a mystery to this very day who the arsonist was and his or her motives to destory Snyder's semi-circular prototypes. No one was ever charged with this crime. Eighty years later it would not take much to see how the Northrop YF 23 looks a lot like the wing of the Arup #5...of course its powered by ultra high thrust jet engines and canted V tail. D.O.

Thanks for comining: I have over 40,000 photographics, drawings, images of aircraft. I've been collecting since I was ten years old. I now have perhaps the largest private photo collection in the world. I continue to collect. From the Chinese J-20 stealth supersonic supercruiser and Northrop's proposed YB-23 medium bomber based on their YF-23 fighter which lost out to the Lockheed F-22 "Raptor." I enjoy sharing these images. After published nearly 40 aviation history books ebooks are next.
