Abstract: An exemplary electric distributed propulsion system includes two or more rotors that are individually controlled by the rotational speed of associated motors, an input control connected to the associated motors to provide rotational speed control to the two or more rotors to produce a desired net thrust, and a logic connected to the input control and the associated motors, the logic for controlling speed and direction of the two or more rotors to achieve the desired net thrust and to avoid a motor speed condition.

Abstract: A cyclic stick for transmitting control commands to blades of a rotorcraft via at least one transmission member, including a grip configured for engagement with a pilot's hand, a control arm and at least one locking mechanism. The control arm has a bottom end configured for connection to the transmission member(s) and for rotational connection to a base support structure, and a top end pivotally connected to the grip. The control arm includes first and second arm portions pivotally connected to each other, the first arm portion defining the bottom end, the second arm portion defining the top end. The locking mechanism(s) selectively prevent a relative pivoting motion between the first and second arm portions and a relative pivoting motion between the second arm portion and the grip. A method of adjusting a position of a grip of a cyclic stick in a rotorcraft cabin is also discussed.

Abstract: Systems and methods include providing an aircraft with a fuselage, an airframe that provides structural rigidity to the fuselage, and at least one door that allows access to an interior of the fuselage through an opening in the fuselage. The aircraft includes an overlapping, tongue and groove door interface formed between a frame of the door and a portion of the airframe that at least partially borders the opening in the fuselage. At least a portion of the airframe includes a concavity. At least a portion of the door frame includes a complementary shaped profile to the concavity of the airframe. The complementary profile of the door frame and the concavity of the airframe form a seal between the door frame and the airframe when the complementary portion is at least partially received within the concavity by selectively rotating the door to its closed position.

Abstract: A yaw control system for a rotorcraft featuring a floor mounted pair of pedals configured to measure an up and down motion of a pair of pedals and utilize that up and down motion as a yaw moment control input. The pair of pedals can rock laterally, fore and aft, or vertically. The pair of pedals can be mechanically interconnected to other pairs of pedals or electrically interconnected to duplicate motion across pairs of pedals.
