In a helicopter having a power shaft with a main axis and bearings for supporting an even number of blades for pivoting about their longitudinal axes, arms mounted on the respective blades for pivoting them in the same and opposite directions for cyclic and total pitch control, respectively, a featured control lever mounted intermediate its ends on a first pivot which lies in a first plane in which the main axis lies, with the control lever having movability of first and second kinds bodily with its pivot axis in the first plane and rockable about its pivot axis, respectively, links connecting the ends of the control lever with the free ends of the arms for pivoting the blades in first and second directions on movements of the control lever of the first and second kinds, respectively, an axially immovable control shaft turning with the power shaft, a swashplate mounted on the control shaft for universal movement on the latter, a first operating connection between the swashplate and first pivot, and including a follower member slidable on the control shaft and in follower relation with the swashplate, to impart to the control lever movement of one of said kinds on axial motion of the follower member, a manual control member operatively connected with the swashplate and operable for shifting the latter into any of its universal positions, another manual control member, a second operative connection between the other control member and control lever for imparting to the latter movement of the other kind on manipulation of the other control member.

In a helicopter, the combination with a power shaft having a main axis and bearings for supporting an even number of blades for individual pivoting about their longitudinal axes, arms mounted with one end on said blades, respectively, for pivoting the latter in the same and opposite directions for cyclic and total pitch control, respectively, of a control lever mounted intermediate its ends on a first pivot with a first axis which lies in a first plane in which said main axis lies, with said control lever having movability of first and second kinds bodily with its pivot axis in said plane and rockable about its pivot axis, respectively, links connecting the opposite ends of said control lever with the other ends of said arms for pivoting said blades in first and second directions on movements of said control lever of said first and second kinds, respectively, an axially immovable control shaft turning with the power shaft and having a universal bearing, a swashplate mounted on said universal bearing and turning with the control shaft, a first operating connection between said swashplate and first pivot, and including a follower member slidable on said control shaft and in follower relation with the swashplate, to impart to said control lever movement of one of said kinds on axial motion of said follower member, a manual control member operatively connected with the swashplate and operable for shifting the latter into any of its universal positions, another manual control member, a second operative connection between said other control member and control lever for imparting to the latter movement of said other kind on manipulating said other control member.
