“…A number of investigations on search for, so‐called, pro‐composite fuselage structures, ie, structures which allow to realize the potential of high‐strength carbon fibers better, was carried out in TsAGI. This work was carried out together with the European and domestic partners (DLR, Airbus, EADS, TUDelft, TUBS, University of Leeds, CRISM, MIPT, MUCTR).…”

The frame (truss) layout based on the hybrid metal‐composite rod elements is proposed for weight saving of the primary aircraft structures. It is proposed to provide the durability of rod elements by protection system against impacts and environment. The algorithm of designing the structure with frame layout has been developed on the basis of 2‐level approach. Fast strength analysis methods based on automated numerical models have been developed. The results of comparative weight estimations of frame and conventional wing box structure of prospective civil aircraft are presented.

“…R. Fangueiro et al successfully used the RTM process to prepare three-way pipes [ 12 ], but the RTM equipment cost is too high. Compared with RTM, fiber winding with advantages of low cost and high efficiency is more suitable for producing tee pipes with good mechanical properties [ 13 , 14 , 15 ]. Moreover, as the industrial robot develops, robotic filament winding technology with high degrees of freedom is applied to manufacture complex shape parts [ 16 ].…”

With the advantages of high specific strength and well corrosion resistance, polymer-matrix composite tee pipes are widely used in aerospace and civilian fields. The robotic filament winding technology is suitable for forming complex shape parts. This paper aims to provide a novel non-geodesic trajectory design method to get a continuous trajectory for tee pipe winding. Furthermore, post-processing methods are proposed for realizing the full coverage of tee pipes by robotic filament winding. The CAD/CAM software is then designed to simulate the winding process and realize the cover of the whole tee pipe. Finally, experiments of winding a tee pipe with a desktop winding machine and a six-axis winding robot are carried out. The results show that the tee pipe is fully covered, verifying the accuracy of the design method and post-processing methods.

“…Due to the manufacturing constraints and disadvantages of metallic isogrid LCS structures, several studies on more general composite anisogrid geodesic designs have been conducted, covering design [9][10][11], manufacturing [12], mechanical properties [13], buckling [5], failure [14], and applications [2,[15][16][17][18], to name only a few. Structural models of the lattice may be simplified by "smearing out", averaging, or taking mean values of the lattice properties and considering them as a solid continuous sheet of isotropic material with elastic properties [8,[19][20][21][22]. Alternatively, more precise but more complex approaches may be used in conjunction with finite element technology, when using numerical computational analysis tools [5,6,21,23].…”
