Control means primarily for rotary-wing aircraft

Claim 2

Rotary-wing aircraft with at least one wobble plate for the cyclic and simultaneous pitch control and servomotors for the pitch change, characterized by a control input plate (1) which is swingable by the control stick (12) and which is supported for universal tilting and a control input plate (2) which is arranged coaxially to said control input plaTe (1) and which is axially movable by means of the pitch change lever (17) and further characterized by at least three electrical slide rheostats (19) which extend between and approximately perpendicularly to the two control input plates, and are arranged at equal angular spacing around the periphery of said control input plates and are connected in circuit with the associated servomotors (24) for their control, said slide rheostats consisting each of a core member (20) and a wiper rod (23) movably arranged in said core member, whereby one end of each core member is connected for universal pivoting with respect to the one control input plate and one end of each wiper rod is connected for universal pivoting with respect to the other control input plate.

Claim 3

Rotary-wing aircraft according to claim 1, characterized in that the wiper rods (23) are connected to the universally tiltable control input plate (1) and the core members (20) are connected to the axially movable control input plate (2).

Claim 4

Control means for rotary-winged aircraft which aircraft has at least one wobble plate for both the cyclic and simultaneous pitch control of the wings thereof and servomotors for effecting operation of said wobble plate, said control means including: a shaft and means mounting same in a fixed position with respect to the aircraft; a first control input plate responsive to movement of a first control device and mounted on said shaft for universal pivotal movement about a single point on said shaft; a second control plate responsive to movement of a second control device and arranged in fixed orientation with respect to said shaft and movable axially therealong; at least three control devices operable in response to rectilinear motion, said devices arranged between said control plates and spaced angularly therearound, one end of each of said control devices being arranged for universal pivotal connection to the first of said control plates and the other end of each of said control devices being arranged for universal pivotal connection to the other control plate, the output of said control devices being applied to said servomotors; whereby actuation of the first of said control plates will energize said servomotors in a selected pattern and actuation of the second of said control plates will actuate said servomotors simultaneously.

Claim 5

Control means for rotary-winged aircraft which aircraft has at least one wobble plate for both the cyclic and simultaneous pitch control of the wings thereof and servomotors for effecting operation of said wobble plate, said control means including: a shaft and means mounting same in a fixed position with respect to the aircraft; a first control input plate responsive to movement of a first control device and mounted on said shaft for universal pivotal movement about a single point on said shaft; a second control plate responsive to movement of a second control device and arranged in fixed orientation with respect to said shaft and movable axially therealong; at least three control devices operable in response to rectilinear motion, said devices arranged between said control plates and spaced angularly therearound, one end of each of said control devices being arranged for universal pivotal connection to the first of said control plates and the other end of each of said control devices being arranged for universal pivotal connection to the other control plate, the output of said control devices being applied to said servomotors; whereby actuation of the first of said control plates will energize said servomotors in a selected pattern and actuation of the second of said control plates will actuate said servomotors simultaneously.

Claim 6

Rotary-wing aircraft with at least one wobble plate for the cyclic and simultaneous pitch control and servomotors for the pitch change, characterized by a control input plate (1) which is swingable by the control stick (12) and which is supported for universal tilting and a control input plate (2) which is arranged coaxially to said control input plate (1) and which is axially movable by means of the pitch change lever (17), and further characterized by at least three voltage changing devices operating by rectilinear mechanical motion extending between, connected to, and arranged normally to two control input plates, and are arranged at equal angular spacing around the periphery of said control input plates and are connected in circuit with the associated servomotors (24) for their control.

Claim 7

Rotary-wing aircraft with at least one wobble plate for the cyclic and simultaneous pitch control and servomotors for the pitch change, characterized by a control input plate (1) which is swingable by the control stick (12) and which is supported for universal tilting and a control input plate (2) which is arranged coaxially to said control input plate (1) and which is axially movable by means of the pitch change lever (17), and further characterized by at least three voltage changing devices operating by rectilinear mechanical motion extending between, connected to, and arranged normally to two control input plates, and are arranged at equal angular spacing around the periphery of said control input plates and are connected in circuit with the associated servomotors (24) for their control.
