VTOL Aircraft Fan Tilting Mechanisms and Arrangements

An aircraft comprising:

• a fuselage;
• at least one wing coupled to the fuselage;
• a plurality of support elements coupled to an underside of the at least one wing;
• a plurality of tilting fans each coupled to a support element among the plurality of support elements via a tilting mechanism;
• a first actuator configured to simultaneously actuate a first group of tilting fans to move between a vertical lift position and a forward flight position, wherein the first group of tilting fans are configured to move to the vertical lift position upon a failure.

An aircraft comprising:

• a fuselage;
• at least one wing coupled to the fuselage;
• a plurality of front tilting fans each coupled to a leading edge of the at least one wing via a tilting mechanism;
• a first actuator configured to simultaneously actuate a first group of the front tilting fans to move between a vertical lift position and a forward flight position;
• and
• a plurality of variable pitch mechanisms each coupled to one of the plurality of front tilting fans, wherein each variable pitch mechanism is configured to adjust a pitch of blades of corresponding front tilting fan based on a direction or a speed of the aircraft.
