Topology Optimization of Adaptive Compliant Aircraft Wing Leading Edge

A network analysis technique is introduced which may be used for determining and parameterizing the load paths in a lattice structure to enable a load path-based topology optimization to be carried out in a way that permits the use of Genetic Algorithms. This technique provides the designer with a greater level of control over the problem complexity than alternative schemes and enables the use of complex starting topologies. The optimization process is implemented in commercially-available software – Samcef and Boss-quattro – and a complete design process of an adaptive compliant aircraft wing rib from conception via optimization to fabrication of a demonstration model is illustrated.
