Muscle power propulsion system for helicopter - has tension rods connecting pedals to main cranks and lever system transmitting drive to main sprocket

摘要

The muscle power propulsion system for a helicopter has main crank arms connected to the pedals (x) by rods (c). The latter extend downwards on either side of the pilot and have roller crossheads (30) running in vertical guideways. The flywheel has a balance-weight, drive transmission to the main sprocket (i) being by connecting rods (g) extending from the crank arms to lever arms (f, f') on a transverse pivot (j) in the main frame. Connecting rods (ko) from the other ends of the levers extend to crankpins (kz) on the wheel.
