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.

Abstract: A multimodal unmanned aerial system (10) includes a fuselage (12) forming a payload bay (22), a control wing (14) forward of the fuselage (12) including a first plurality of propulsion assemblies (30,32) and a primary wing (16) aft of the fuselage (12) including a second plurality of propulsion assemblies (34, 36). The primary wing (16) has a greater wingspan than the control wing (14). The multimodal unmanned aerial system (10) includes linkages (40, 42, 44, 46) rotatably coupling the fuselage (12) to the control wing (14) and the primary wing (16). The fuselage (12), the control wing (14) and the primary wing (16) are configured to synchronously rotate between a vertical takeoff and landing flight mode and a forward flight mode. The fuselage (12), the control wing (14) and the primary wing (16) are substantially vertical in the vertical takeoff and landing flight mode and substantially horizontal in the forward flight mode.

Abstract: A weighing system includes a support, a load cell mounted to the support, and a part platform suspended from the load cell to receive a part to be weighed. The load cell is operable to generate thousands of weight values for the part per second over a period of less than twenty seconds. The load cell is operable to output a weight of the part by averaging the weight values over the period of less than twenty seconds. A method of weighing the part suspended from the load cell is also disclosed.

Abstract: A cart for supporting a part to be inspected in a non-destructive testing (NDT) machine. The cart includes a base with wheels, a first support extending upright from the base, a second support extending upright from the base, and mounting fixtures being removably attachable to the first and second supports and having mounting ends engageable with the part to support the part from the first support or the second support. The base is displaceable with the wheels to enter and exit the NDT machine. The cart is lockable upon being within the NDT machine to secure the cart in position.

Abstract: ABSTRACT A bonded part includes a first surface facing toward a second surface, and a cured adhesive between the first and second surfaces defining a bond line. A surface structure on the first surface is within the bond line and has surface protrusions arranged in a pattern. Each surface protrusion protrudes outwardly from a first end at the first surface to a second end adjacent to the second surface. A thickness of the surface protrusions is substantially equal to the thickness of the bond line. The cured adhesive extends around the surface protrusions. The thickness of the bond line between the first and second surfaces is substantially constant along the bond line, and is greater than a thickness of the cured adhesive between the second ends of the protrusions and the second surface.

Abstract: An autonomous cargo delivery aircraft operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft includes a fuselage having an aerodynamic shape with a leading edge, a trailing edge and first and second sides. First and second wings are coupled to the fuselage proximate the first and second sides, respectively. A distributed thrust array includes a first pair of propulsion assemblies coupled to the first wing and a second pair of propulsion assemblies coupled to the second wing. A flight control system is operably associated with the distributed thrust array and configured to independently control each of the propulsion assemblies. The first side of the fuselage includes a door configured to provide access to a cargo bay disposed within the fuselage from an exterior of the aircraft with a predetermined clearance relative to the first pair of propulsion assemblies.

Abstract: A series of heated control sticks for rotorcrafts, tiltrotors, and helicopters. The heated collective and cyclic sticks feature several heater assemblies to provide localized heating for pilots and co-pilots. The heater assemblies are formed from several layers of fabrics and resistive materials designed to generate heat while current is provided to conductive materials in the resistive material. A controller provides individualized control for users to adjust the temperature of various zones associated with either the collective stick or the cyclic stick. The heater assemblies can be installed entirely external to the stick like in a retrofit or partially internally.

Abstract: A configurable electrical architecture for an eVTOL aircraft having a takeoff and landing power mode and a cruise power mode. The configurable electrical architecture includes a power-optimized power source including a high-power battery array and an energy-optimized power source selected from a plurality of interchangeable energy-optimized power sources including a high-energy battery array, a hydrogen fuel cell system and a turbo-generator system. A distribution system is electrically coupled to the power-optimized power source and the energy-optimized power source. At least one electric motor is electrically coupled to the distribution system. In the takeoff and landing power mode, both the power-optimized power source and the energy-optimized power source provide electrical power to the at least one electric motor. In the cruise power mode, the energy-optimized power source provides electrical power to the at least one electric motor and to the power-optimized power source to recharge the high-power battery array.
