Tilt rotor systems and methods for EVTOL aircraft

A VTOL (Vertical Takeoff and Landing) aircraft comprising:

• a pinion that moves with a proprotor and is engaged with a first gear such that the pinion revolves around at least a portion of the first gear, wherein revolution of the pinion causes the pinion to rotate;
• a cam that is fixedly connected to the pinion such that the cam rotates with the pinion;
• and
• a control rod operatively coupled at a first end with the cam such that rotation of the cam causes translation of the control rod to alter a pitch of blades.

A method of operating a VTOL (Vertical Takeoff and Landing) aircraft comprising:

• tilting a proprotor of the aircraft, wherein:
• a first gear is fixed in position relative to a fixed frame,
• a pinion moves with the proprotor and is engaged with the first gear such that the pinion revolves around at least a portion of the first gear, wherein revolution of the pinion causes the pinion to rotate,
• a cam is fixedly connected to the pinion such that the cam rotates with the pinion, and
• a control rod is operatively coupled at a first end with the cam such that rotation of the cam causes translation of the control rod to alter a pitch of blades of the proprotor.

A proprotor tilting system, comprising:

• a first frame for mounting to an aircraft;
• a second frame for mounting a proprotor, wherein the second frame is rotatably mounted to the first frame;
• a tilt actuator configured to tilt the second frame with respect to the first frame;
• a cam configured to rotate when a tilt actuator tilts the second frame;
• and
• a control rod operatively coupled at a first end with the cam such that rotation of the cam causes translation of the control rod to alter a pitch of blades.

A VTOL (Vertical Takeoff and Landing) aircraft comprising:

• a frame for mounting a proprotor of the aircraft;
• a tilt actuator configured to tilt the frame;
• a cam configured to rotate when the tilt actuator tilts the frame;
• and
• a control rod operatively coupled at a first end with the cam such that rotation of the cam causes translation of the control rod to alter a pitch of blades.

A method of operating a VTOL (Vertical Takeoff and Landing) aircraft comprising:

• tilting, by a tilt actuator, a frame for mounting a proprotor of the aircraft, wherein:
• a cam is configured to rotate when the tilt actuator tilts the frame;
• and
• a control rod operatively coupled at a first end with the cam such that rotation of the cam causes translation of the control rod to alter a pitch of blades.
