A Review: Aeronautical Components and Systems Should have their Weight Reduced throughout the Design Process

Lightweight requires cutting-edge materials and imaginative engineering to achieve the same or better technical performance with less material. This approach has been widely used in automobiles, fashion, and packaging, and the aviation sector may benefit from it. Traditional lightweight methods have used high-performance materials like composites, structural optimization using computationally-aided engineering, and cutting-edge manufacturing processes including additive manufacturing, foam metals, and hot forming. This article will examine the most prevalent lightweight technologies and their possible usage in aviation, such as power plants and airframe components. Solar-powered aircraft wings require improvement and are open to lightweight technology. High aspect ratios cause non-linear distortion, aileron reversal, flutter, and rigid-elastic coupling. Lightweight aircraft, UAVs, and rocket subsystems are all being considered. Cutting-edge optimization methods may optimize structural elements and geometrical parameters for optimum structural stiffness, least mass, and energy storage. Additive manufacturing may create composite or multi-material components that can serve several purposes.
