摘要： A method for minimizing the weight of an internally pressurized aircraft fuselage of a type that includes an elongated tubular shell having a near-elliptical cross-section with a radius R(&phgr;)- and a curvature Curv(&phgr;), where &phgr; is a roll elevation angle of the shell, includes tailoring at least one structural attribute of the shell as a function of at least one of the elevation angle &phgr;, R(&phgr;) and Curv(&phgr;) so as to reduce the weight of the fuselage relative to an identical fuselage shell in which the same at least one structural attribute has not been so tailored.

摘要： An ultralight aircraft is described, in particular a helicopter, falling within the limits of a basic weight ranging from 210 to 230 kg and a maximum weight of 450 kg, the length (L) of which ranges between 4950 and 5150 mm. The structure (50), constituting the characteristic framework of the helicopter, is formed by several tubular elements of titanium alloy which converge in a plurality of central knots (KC1...KC4) lying on the helicopter's symmetry plane, and of pairs of lateral knots (KL1...KL7) symmetrical with respect to said plane, the spatial position of which, referred to a triad of axes, is defined in relation to the length (M) of the structure selected as a basic parameter.

摘要： In exemplary implementations of this invention, a digital material comprising many discrete units is used to fabricate a sparse structure. The units are reversibly joined by elastic connections. Each unit comprises fiber-reinforced composite material. Each unit is small compared to the sparse structure as a whole. Likewise, in a sparse structure made from this digital material, the number of types of units is small compared to the total number of units. The digital material is anisotropic. This anisotropy may be due to different fiber orientations within each unit. Furthermore, different units in a single sparse structure may be oriented in different directions and in different, non-parallel planes. In some cases, the digital material is reinforced with carbon fibers, and connections between units are stronger than the units themselves. The small discrete units may be assembled into a strong, lightweight sparse structure, such as an airframe.

摘要： A structural support having fractal-stiffening and method of fabricating the support is presented where an optimized location of at least three nodes (1') is predetermined prior to fabricating the structural support where a first set of webs (2') is formed on one side of the support and joined to the nodes (1') to form a first pocket region (8'). A second set of webs (27) is formed within the first pocket region (8') forming a second pocket region (31) where the height of the first set of webs (2') extending orthogonally from the side of the support is greater than the second set of webs (27) extending orthogonally from the support.

摘要： An aircraft fuselage includes a tubular shell having a centerline axis, opposite ends, and a cross-section having a radius R(phi), where phi is the angular coordinate of a cylindrical coordinate system, a curvature Curv(phi), where Curv(phi) is the inverse of a local radius of curvature of a surface of the shell, and a circumferential shape that varies radially by no more than ±7% from that of an elliptical cross-section at substantially every station along the centerline axis between the nose and tail ends thereof. The weight of the shell is minimized by "tailoring," i.e., optimizing, at least one structural attribute, expressed as a function of phi, associated with every element of the shell, such that the weight of the shell required to react a design load incident thereon is less than that required to react the same design load, but wherein the same structural attribute has not been so tailored.
