Weight reduction plays a vital role in enhancing the operational efficiency of an aircraft. Reducing the aircraft components’ weights can also lessen fuel consumption and environmental impacts. Thus, finding advanced solutions that help save aircraft weight is necessary. This study focuses on the applications of topology optimization, lattice optimization, and some aspects of “design for AM” in innovating a jet engine bracket. The developed brackets are then virtually analyzed regarding equivalent stress, total deformation, and safety factors. The results of this study provide evidence that can support the development of similar simulation-driven design processes and can extendedly be employed to develop many other green components for the aviation industry.
