FR2628063A1 - Human powered helicopter - has upper rotor powered directly by hand crank assisted by foot crank pulley and cables also driving lower rotor in opposite direction - Google Patents

Abstract

The human powered helicopter has two contra rotating rotors (1,8) lifting a cabin (13) which contains the pilot. The pilot sits on a stool (16) and uses both arms and legs to drive the rotors. The upper rotor (1) is connected directly by a shaft (2) to a hand cranks (4) via a ball joint (5). The shaft is also connected to a pulley (3) which is driven by a cable from a foot pedal operated crankshaft (12). The cable passes over guide pullies around the drive pulley 3 over two fasther guide pulleys and around the second drive pulley (7) before returning to the crankshaft. The cabin is fitted with wheels (15) and a coil spring suspension (14). ADVANTAGE - The helicopter maximises the use of the pilot's strength by combining both arm and leg drive systems.

claims

  I - helicopter-type aircraft operated by muscular force, characterized in that two propellers rotate in opposite directions, one with direct drive (I), the other (8) rotating in opposite directions, are respectively actuated by a crank (4 ) by hand and by a pedal (I2)

  using the strength of the arms and legs.

  2 - aircraft according to lcL claim I characterized in that the muscle strength of the arms and legs is used by adding them; ig2) by capturing the energy by the crank (4) for the arms, and by capturing the energy from the legs by the crankshaft (I2), these two energies are added to activate the propellers

  3 - aircraft according to any of the claims

  previous characterized in that with a single belt we capture the power of the arms then that of the legs and that we distribute the energy to the two propellers rotating in opposite directions) (ig 2 and 3). We capture the energy of the arms with the crank (4) which directly actuates the propeller (I) and (2) and at the same time the pulley (3) secured around which the belt (I7) passes. The energy of the legs is captured by the crankshaft (I2) which actuates a pulley (6) around which the belt (I7) and the references (IO) and (II) directs the energy to the discs (3) and (7 ) and rotates them in opposite directions. The returns (I8) and (I9) complete the system (9- * T i j .._: .__, r Qq4 A) G gij2
