Abstract
Abstract A rotor setting system in conjunction with an aerodynamic-body control. The setting system is characterized by a rotor which comprises a console, a rotary drive for the rotor, setting members for the control of the aerodynamic body, especially rudders or spoilers, as well as a control unit for the rotor, and further including a control unit on the sides of the aerodynamic body, wherein the two control units cooperate with each other for adjusting the setting members.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
263 words
A rotor setting system for an aerodynamic body comprising: rotor means comprising support means rotatably mounted on the aerodynamic body; rotary drive means for driving said rotor means in rotation; said rotary drive means comprising setting means for controlling the flight path of the aerodynamic body rotatably mounted on the support means; first control means for controlling the rotation of the rotor means; and second control means coupled to said setting means for controlling the orientation of said setting means, said second control means being coupled to said first control means by said support means and cooperating with said first control means to set said setting means, said second control means being coupled to said setting means via a first shaft means, said shaft means having a cam means mounted thereon cooperating with a projection means coupled to said setting means for changing the orientation of a surface of said setting means with respect to a longitudinal axis of said aerodynamic body, and said setting means being mounted on a second shaft means disposed transversely to said rotor means and having said projection disposed thereon in abutment with said cam means, said rotor means further being coupled to said second control means via spring means coupled to said first shaft means for limiting movement between said second control means and said rotor means, whereby when said first control means determines a position of said rotor means with respect to said aerodynamic body, said second control means adjusts the orientation of said setting means thereby to determine the flight path of the aerodynamic body.
Claim 2
Dependent Claim
263 words
A rotor setting system for an aerodynamic body comprising: rotor means comprising support means rotatably mounted on the aerodynamic body; rotary drive means for driving said rotor means in rotation; said rotary drive means comprising setting means for controlling the flight path of the aerodynamic body rotatably mounted on the support means; first control means for controlling the rotation of the rotor means; and second control means coupled to said setting means for controlling the orientation of said setting means, said second control means being coupled to said first control means by said support means and cooperating with said first control means to set said setting means, said second control means being coupled to said setting means via a first shaft means, said shaft means having a cam means mounted thereon cooperating with a projection means coupled to said setting means for changing the orientation of a surface of said setting means with respect to a longitudinal axis of said aerodynamic body, and said setting means being mounted on a second shaft means disposed transversely to said rotor means and having said projection disposed thereon in abutment with said cam means, said rotor means further being coupled to said second control means via spring means coupled to said first shaft means for limiting movement between said second control means and said rotor means, whereby when said first control means determines a position of said rotor means with respect to said aerodynamic body, said second control means adjusts the orientation of said setting means thereby to determine the flight path of the aerodynamic body.
Claim 3
Dependent Claim
26 words
The rotor setting system recited in claim 1, wherein power for actuating the setting means is taken from the rotary drive means for the rotor means.
Claim 4
Dependent Claim
28 words
The rotor setting system recited in claim 1, wherein the rotary drive means for the rotor means comprises drive means arranged between the aerodynamic body and the rotor.
Claim 5
Dependent Claim
28 words
The rotor setting system recited in claim 3, wherein said drive means comprises one of an electric motor, a pneumatic system, a hydraulic system or a spring drive.
Claim 6
Dependent Claim
21 words
The rotor setting system recited in claim 1, further comprising angle-of-rotation transmitters provided between the rotor means and the aerodynamic body.
Claim 7
Dependent Claim
50 words
The rotor setting system recited in claim 1, wherein, at the tip of the aerodynamic body, a forward-protruding rotary unit means is provided which supports the setting means, and within the rotary unit the first control means cooperating with the second control means is provided for adjusting the setting means.
Claim 8
Dependent Claim
24 words
The rotor setting system recited in claim 6, wherein the setting means comprises at least two rudder means having a common axis of rotation.
Claim 9
Dependent Claim
37 words
The rotor setting system recited in claim 7, wherein at least one rudder means can be actuated independently of the other or both rudder means can be actuated independently of each other by the first control means.
Claim 10
Dependent Claim
40 words
The rotor setting system recited in claim 6, wherein the control means for actuating the setting means is spring-loaded in order to bring the setting means into the rest position if the first and second control means are not actuated.
