Preliminary Structural Design of Coreless Spoiler by Topological Optimization

Most spoilers are made from a sandwich structure with honeycomb component as its core. However, the core is sensitive to water ingress, causing damage control surface due weak moisture-resistance behavior. This study aimed conduct design and analysis of an improved composite for coreless spoiler. A spoiler aircraft, A320, was used case study. The weaknesses were identified through finite element via Abaqus software. Multi-spar multi-rib designs studied compared topological optimization. variables evaluation Tsai–Hill failure index critical buckling load. most potential considered parametric optimization obtain satisfactory configuration. results showed that upper skin without failed criteria. Furthermore, show multi-spar configuration outperformed final achieved mass reduction 24% original additional 6% by re-designing internal structures violating In conclusion, have been identified, has proposed.
