hubs 23 and 26 during gyration the blades 35 36 37 38 turn accurate half of what their holding star does this happens because the geared hub 23 is revolved by shaft 40 via the shaft bulge 24 and hollow shaft 14 holding said hub 23 this compel the gear 11 run round still gear 57 and thus to revolve along with the bevel gear 39 which in turn transmits revolution to the blades via the gear 13 shaft 12 and bevel gear couple 34 2 normally created thrust force directs up vertically becoming totally a lift force for the rotopter maneuvering the thrust force of each thrust propellor can be reduced or increased or also inclined forward or back diminishing of produced turbine power can synchronically reduce thrust forces this compels the rotopter to land whereas the turbine acceleration enforces the rotopter climb up applying any of the brakes 83 84 fig1 reduces the thrust force of the associated propellor allowing the rotopter to make roll or bank with combined turn the turn is accomplished by opposite thrust inclinations of the propellers even thrust inclinations lets the rotopter increase forward or back depending of inclination direction described inclining operations are produced by the control drive 10 via the united gears 22 and 57 which need to be turn by said driver to the angle of the same direction and double volume of the desired thrust inclination angle then the inclination angle is presented as constant addition to altering blade angle orientations this is that makes the thrust to be desirable inclined the main lift force is the resistance of blade on descending circular path the blade flat oriented and possessing velocity v treats resistance force f determined as follows 1.
