摘要:
The present invention refers to the configuration and manufacturing process of a rib (22) for the construction of an aircraft torsion box. In the method a flat stack of plies of composite material (13) is layered up, which is then cut to form a flat pre-form (14) having an outer contour (15) configuring flanges, and an internal contour configuring two or more diagonal truss (16) with flanges (17) at opposite sides. The flat pre-form (14) is press-formed to fold the flanges of the outer and internal contour to form a rib pre-form, which is finally cured. The invention also refers to a composite rib (22) obtained as an unitary body by conforming a single pre-form of stacked plies. The invention allows the manufacture of the rib (22) in one-shot process, integrating all its components, such as the assembly time and cost of the rib are minimized.
摘要:
The present invention relates generally to a system that monitors the condition of hydraulic systems for an aircraft or for other applications and, more particularly, to a system and method for detecting leakage within the hydraulic system aboard an aircraft. Such system is detecting hydraulic liquids by extended sensors based on the collapse of percolation conductivity (COPC) which sensors are covering an area in the aircraft.

Disclosed is a method of producing part of an airframe (4) for attachment to a system (5). The method comprises: providing an initial structure;providing a reference structure (64); positioning the initial structure with respect to the reference structure (64) such that its position/orientation relative to the reference structure (64) is the same as the position/orientation relative to the system (5) that it would have if the part of the airframe (4) was attached to the system (5); specifying an inner mould line;applying, to an outer surface of the initial structure, material (90); and machining the material (90) such that the position/orientation of the outer surface of the material (90) with respect to the reference structure (64) is the same as the position/orientation with respect to the system (5) that the inner mould line would have if the part of the airframe (4) was attached to the system (5).

A coating application system (200) may include a pair of towers (210, 212) movable along a respective pair of floor tracks (242, 244). A crossbeam (300) may extend between the pair of towers. The cross beam may have opposing beam ends. A universal joint (310) may couple each beam end to a tower to allow the crossbeam to rotate about a vertical axis and about a horizontal axis. A robotic device (400) may be mounted to the crossbeam. The robotic device may include an end effector (416) for performing one or more operations on an aircraft exterior surface.
