Abstract: Methods and apparatus for varying a trim of a vehicle are provided. A nose cone assembly for a vehicle includes an angle cone portion and a nose cone portion rotatably coupled to the angle cone portion. The angle cone portion and the nose cone portion are arranged such that a plane of rotation between the angle cone portion and the nose cone portion is slanted at an angle relative to a plane perpendicular to a long axis of the vehicle. The angle cone portion rotates relative to the vehicle body about the long axis. The nose cone portion rotates relative to the angle cone portion about an axis normal to the plane of rotation. A tip of the nose cone portion varies in position relative to the long axis of the vehicle based on the rotation of the angle cone portion and the rotation of the nose cone portion.

Abstract: Methods and apparatus for driving rotational elements of a vehicle are provided. The apparatus includes a first driving member configured to rotate a first rotational element of the vehicle relative to a body of the vehicle. The apparatus also includes a second driving member. The second driving member includes a drive structure rotatably coupled to the body. The second driving member also includes a gimbal element coupled to the drive structure via a first joint pin. The gimbal element is configured to couple to a second rotational element of the vehicle such that when the drive structure is rotated relative to the body, the second rotational element rotates relative to the first rotational element. The gimbal element is configured to pivot about the first joint pin relative to the drive structure based on the rotation of the first rotational element and the rotation of the second rotational element.
