Abstract: An aircraft includes an airframe and a distributed thrust array coupled to the airframe including at least six propulsion assemblies. A flight control system is operably associated with the distributed thrust array and is operable to independently control each of the propulsion assemblies. A package delivery module is coupled to the airframe. In a VTOL orientation utilizing thrust-borne lift, a first pair of propulsion assemblies is forward of the package delivery module, a second pair of propulsion assemblies is aft of the package delivery module and a third pair of propulsion assemblies is lateral of the package delivery module. In a forward flight orientation utilizing wing-borne lift, the first pair of propulsion assemblies is below the package delivery module, the second pair of propulsion assemblies is above the package delivery module and the third pair of propulsion assemblies is lateral of the package delivery module.

Abstract: A method of preparing a composite article including providing a first bias assembly with a first bias roll; providing a first non-bias assembly with a first non-bias roll; positioning the first bias assembly to a dispensing position; dispensing a bias ply from the first bias roll along a bias path on a mold; cutting the bias ply; positioning the first non-bias assembly to a dispensing position; dispensing a non-bias ply from the first non-bias roll; and cutting the non-bias ply; wherein the bias path and the non-bias path are substantially parallel.

Abstract: A rotor assembly for generating thrust for a vehicle. The rotor assembly includes a rotor hub and a plurality of rotor blade assemblies coupled to the rotor hub. Each rotor blade assembly includes a metallic bearing race, a composite rotor blade and a metallic coupling assembly. The composite rotor blade has a root section with a radially outwardly tapered outer surface. The metallic coupling assembly has a radially inwardly tapered inner surface that receives the radially outwardly tapered outer surface of the root section of the rotor blade therein to provide a centrifugal force seat for the rotor blade. The coupling assembly includes at least two circumferentially distributed coupling members. The coupling assembly is configured to couple the rotor blade to the bearing race and to provide a centrifugal force load path therebetween.

Abstract: An aircraft for capturing drones includes an airframe having a drone channel with first and second wings extending outboard thereof. A two-dimensional distributed thrust array includes a plurality of propulsion assemblies coupled to each of the first and second wings such that the rotor disc of each propulsion assembly is outboard of the drone channel. A flight control system is coupled to the airframe and is operable to independently control each of the propulsion assemblies. A mesh bag is coupled to the drone channel forming a drone capture net. The aircraft is configured to convert between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft is also configured to overtake a drone during flight in the biplane orientation such that the drone passes through the drone channel into the mesh bag, thereby capturing the drone in the drone capture net.

Abstract: An aircraft is 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 extending therebetween forming a central region. A two-dimensional distributed thrust array and a flight control system are coupled to the airframe. A nose cone and an afterbody are each selectively coupled to the airframe. In a cargo delivery flight configuration, the nose cone and the afterbody are coupled to the airframe such that the nose cone and the afterbody each extend between the first and second wings and between first and second pylons to form a cargo enclosure with an aerodynamic outer shape. In a minimal drag flight configuration, the nose cone and the afterbody are not coupled to the airframe such that air passes through the central region during flight.
