Abstract: There is provided a method of manufacturing a composite structure of an aircraft. The composite structure includes a skin and a reinforcing material. The method includes, by stacking unhardened composite sheets on a region of a jig adjacent to a holding portion to hold the reinforcing material, forming a skin inner layer including a retainer to retain two end portions of a flange of the reinforcing material in a width direction of the flange. The method includes installing the reinforcing material at the holding portion of the jig so that the two end portions abut upon the retainer. The method includes, by stacking unhardened composite sheets on an outer surface of the flange and on an outer surface of the skin inner layer, forming a skin outer layer. The method includes hardening the skin inner layer and the skin outer layer.

Abstract: According to one implementation, a flight restriction setup system includes a damage detection unit and a flight restriction calculation unit. The damage detection unit detects a damage which arose in a structure composing an aircraft. The flight restriction calculation unit sets at least one flight restriction of the aircraft according to a degree of the damage detected by the damage detection unit. Further, according to one implementation, a flight restriction setup method includes: detecting a damage, which arose in a structure composing an aircraft, by a damage detection unit; and setting a flight restriction of the aircraft according to a degree of the damage detected by the damage detection unit.

Abstract: A rotorcraft includes a fuselage, rotors and circular wings. The rotors are attached to the fuselage. The rotors are attached to the fuselage. The circular wings are disposed under the rotors respectively. Upper surfaces of the circular wings have annular curved surfaces and thereby are convex upward respectively. The circular wings cause Coanda effects by the upper surfaces respectively. First lift is generated by rotating the rotors. Second lift is generated by the Coanda effects by the circular wings. Third lift is generated by air jets deflected downward along the upper surfaces of the circular wings respectively.

Abstract: A method of designing an anisotropic composite laminate structure to constitute a predetermined member of an airframe structure of an aircraft and includes a plurality of types of composite layers containing reinforcing fibers with different fiber orientations is provided. The method includes dividing the anisotropic composite laminate structure in the predetermined member into a plurality of regions in a thickness direction. The method includes determining, for each of the regions, at least a stacking sequence of the plurality of types of composite layers in accordance with a direction of stress acting on the predetermined member.
