Summary:

The idea of increasing the lift of an aerofoil by subdividing it goes back to gliding flight experiments by the writer before the war. A crash in August, 1917, with a Rumpler C airplane, on account of stalling, caused the idea to be put into concrete form and presented for a patent in 1918. The patent claim reads: "Supporting surface characterized by its being divided into a number of tandem components which together form a wing section." The application was at first rejected because the patent office did not believe in the possibility of increasing the lift by dividing the wing. The issuing patent was made dependent on conclusive proof of such increase.
