Structural Optimization of Aircraft Delta Wings: Project Analysis

This project report provides a comprehensive analysis of the structural optimization of aircraft delta wings. It begins with an introduction to delta wings, their characteristics, and their advantages, particularly in supersonic aircraft. The report outlines different types of delta wings, including tailless, tailed, and cropped delta wings, along with their benefits, such as high-speed performance and vortex lift generation. It also addresses research gaps and limitations, such as stability issues at high angles of attack and high takeoff speeds. The evolution of delta wings is traced from early designs to their widespread use in various aircraft, including the B-58 Hustler and Concorde. The report delves into the properties of materials like titanium, aluminum, and carbon fiber reinforced plastic (CFRP), used in wing construction. The methodology involves structural analysis using software like Designfoil and ANSYS to determine design parameters and optimize wing performance. The results indicate that while titanium alloys offer high strength-to-weight ratios, CFRP provides the best material for optimized aircraft wings due to low weight and deflection. The conclusion emphasizes that the selection of materials and design parameters is crucial for the performance and safety of fighter aircraft.
