“The planes were attached to what was really an endless belt, revolving around two drums, one placed higher than the other, to allow the planes to meet on an independent stratum of air. The planes were set at an angle on the belt, and when in motion gave a strong lifting impetus to the machine. The propelling apparatus also consisted of planes fixed to an endless band, so designed that the planes pushed the air when traveling in one direction, and feathered when returning in the opposite direction.”
Direct-lift flying machine invented in 1909 by Harry Fisher, an early experimenter from Tauherenikau, New Zealand.
He went on to build a monoplane in 1911.
Percy Fisher died in 1941.
