Abstract: An asymmetric aircraft configuration having a first and a second wing, the first wing having a span larger than the second wing. A first engine is mounted on the first wing, and a second engine mounted on the rear end of the aircraft with its centerline aligned with the aircraft longitudinal axis. The rear end of the aircraft has a T tail, and the second engine is configured to ingest and consume air forming a boundary layer during the flight. A main landing gear assembly includes a first landing gear attached to the first wing, and a second landing gear attached to an area of the fuselage close to the second wing.

Abstract: A method for reworking a composite laminate comprising a plurality of tapes, comprising the following steps: detecting the occurrence of a defect on a tape of composite material while the tape is being laid up; continuing the lay-up of the defective tape until a tape length is formed which surpasses a manufacturing length of the tape; catching the part of the defective tape that surpasses the manufacturing length of the tap; cutting the defective tape in the part of the defective tape that surpasses the manufacturing length of the tape; removing from the laminate the caught defective tape by the catching system, and laying-up a replacement tape in the place of the removed defective tape.

Abstract: A configuration and manufacturing method for a trailing edge of an aircraft airfoil, such as a control surface or a lifting surface is described. The trailing edge is formed and configured by upper and lower composite covers, which are stitched to each other with a metallic wire, such as the metallic wire is electrically in contact with upper and lower metallic meshes to provide electrical continuity between meshes. According to a method, upper and lower covers configuring the trailing edge, are stitched with the metallic wire before curing the covers, so that the metallic wire gets embedded within the composite material. A trailing edge for an aircraft airfoil, which is easy to manufacture and that at the same time fulfills aerodynamic, mechanical and electrical conductivity requirements is described.
