Eiffel performed experiments withDorand wings, and found that when the top surface wasstaggered forward by 1/2.5 of the chord (0.4C), and with agap-chord ratio of 0.9, an Increase in lift of from 6 to 10per cent was obtained. The L/D was the same as withno stagger. With thin circular plates, 1/13.5… … Slow Speed, Two-Seat Biplane, with a Large Gap-Chord Ratio. The LargeGap Is Permissible in a Slow Machine, as the Strut Resistance IsLess Than the Gain in Lift-Drag Ratio Obtained by the GreaterGap. It Will Be Noted That These Wings Have a ConsiderableAmount of Stagger. The Position of the Bottom…
