The presence of maximum elastic coupling in the composite box-beam increases the aero-elastic stability of the helicopter rotor blade. The multi-objective design problem is formulated as a
We then proceed with a beam section optimization. Several optimization cases are defined for the important cross sections of the vehicle''s “members” that run much faster than the optimization of the

During optimization, design domains are narrowed down before filtering to obtain the discrete thickness of box-sectioned beam structures.
Figure 4 plots the design found with topology optimization. Four triangles have been cut out and the end of the beam is left unsupported, which allows for a seesaw effect because most of the load is to the

VHTS systems currently assume a uniform distribution of traffic in the service area, but in a real system, traffic demands are not uniform and are dynamic.
While most techniques focus on probabilistic load distributions to manage uncertainties, optimizing deterministic load distributions for specific scenarios remains relatively underexplored, as

The goal of structural optimization is to place material in a design space so that it rests on some fixed points or "normals" and resists a set of applied forces or loads as efficiently as possible.
