The 1954 model has the benefits of a swept wing (the tips are well behind the CG for pitch control) without the problems associated with spanwise flow.

All done without carbon fiber. Amazing.

I wonder if there were ANY high performance flying wings here in the States back then.

Jack Northrop may have had one or two...

Oh sure..... I guess some would say that those were high performance, for what they were. No high aspect ratio sailplanes from Jack though.

not sure if they strictly count as vintage, but Jupp Wimmer's wings certainly have that feel to them- http://flyingwinggliders.blogspot.co...pp-wimmer.html

There were the full-scale Burgess-Dunne wings here 100 years ago:

John Dunne doesn't get the recognition he deserves. He invented the swept wing with washout and elevons at the tips. He patented elevons some time before WWI and one of his 'wings was the first documented inherently stable airplane. It's a shame that heart disease forced him to retire early because at the time nobody understood his theories well enough to continue developing the type.

Speaking of old Nurflügeln: Tailless Tale by Ferdinando Galè has hundreds of drawings and math. It looks like it's still available from the B² book store.

I've always admired the free flight guys. The kings of light wing loading.

I couldn't make out a date on the drawings. Is this design from the 1950's?

Yes 1950/51. All plywood and spruce.

Speaking of older flying wings


I recently acquired a Robbe Geier. I'd like to set it up for winch launching & aerotow but I need the center of gravity and towhook locations. Can anybody help?

Robbe Geier

CG is 106 mm behind the leading edge.
