    Abstract: A material dispensing system including a first frame and a first application head. The first application head supported by the first frame including a first bias ply assembly comprising a bias ply roll supported on a bias ply dispenser unit, the first bias ply assembly configured to pass bias ply material along a bias path; and a first non-bias ply assembly comprising a non-bias ply roll supported by a non-bias ply dispenser unit, the non-bias ply assembly configured to pass non-bias ply material along a non-bias path; wherein the bias path and the non-bias path are substantially parallel. Another aspect provides a material dispensing system including a first frame and a first application head supported thereby; and a second frame and a second application head supported thereby; wherein the first frame and the second frame move in an X direction during operation. Another aspect includes preparing a composite article.

    Abstract: An aircraft includes an airframe and a distributed propulsion system including a plurality of propulsion assemblies coupled to the airframe. Each of the propulsion assemblies includes a nacelle, an engine disposed within the nacelle, a proprotor coupled to the engine and a thrust vectoring system. Each thrust vectoring system includes a pivoting plate, a rotary actuator operable to rotate the pivoting plate about a propulsion assembly centerline axis and a linear actuator operable to pivot the pivoting plate about a pivot axis that is normal to the propulsion assembly centerline axis. The engine is mounted on the pivoting plate such that operation of the pivoting plate enables resolution of a thrust vector within a thrust vector cone.

    Abstract: An aircraft operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft includes an airframe having first and second wings with first and second pylons coupled therebetween. The airframe has a longitudinal axis and a lateral axis in hover. A two-dimensional distributed thrust array is coupled to the airframe. The thrust array includes a plurality of propulsion assemblies each operable for variable speed and omnidirectional thrust vectoring. A flight control system is operable to independently control the speed and thrust vector of each of the propulsion assemblies such that in an inclined flight attitude with at least one of the longitudinal axis and the lateral axis extending out of a horizontal plane, the flight control system is operable to maintain hover stability responsive to controlling the speed and the thrust vector of the propulsion assemblies.

    Abstract: An aerial imaging aircraft operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft includes an airframe having first and second wings with first and second pylons coupled therebetween. The airframe has a longitudinal axis and a lateral axis in the VTOL orientation. A two-dimensional distributed thrust array is coupled to the airframe. The thrust array includes a plurality of propulsion assemblies each operable for variable speed and omnidirectional thrust vectoring. A payload is coupled to the airframe and includes an aerial imaging module. A flight control system is operable to independently control the speed and thrust vector of each of the propulsion assemblies such that in a level or inclined flight attitude, the flight control system is operable to maintain the orientation of the aerial imaging module toward a focal point of a ground object while translating the aircraft.

    Abstract: In some embodiments, an aircraft includes a flying frame having an airframe with first and second wing members having a plurality of pylons extending therebetween, a distributed propulsion system including a plurality of propulsion assemblies securably attached to the airframe and a flight control system operably associated with the distributed propulsion system. The flying frame has a vertical takeoff and landing mode with the wing members disposed in generally the same horizontal plane and a forward flight mode with the wing members disposed in generally the same vertical plane. The flight control system is operable to command the propulsion assemblies responsive to at least one of remote flight control, autonomous flight control and combinations thereof
