Wing Structure Design the RAMP-200

Abstract

This project focuses on the design of the wing structure to increase fatigue resistance and lessen the shear force across the skin of the wings, while maintaining the structure’s stability and soundness. The designed wing structure will be optimized to account for the proposed weight and endurance of the aircraft. The overall wing shape and size was defined using preliminary design methods and optimized for efficiency at Mach 0.9. The main structures were sized using calculations that were programmed into MATLAB and supported by hand calculations. Finite element analysis was used to verify sizing, and the structures were assessed using fatigue life and crack propagation prediction. The designed wing structure will support a higher cruise speed and altitude while maintaining safety requirements. The wing structure will reflect a wing that fits in the modern era facilitating a higher fuel efficiency than competitor airframes. This project demonstrates a design balance between strength, weight, cost, durability, and fatigue resistance to reduce the inspection and maintenance intervals of the wing thereby saving on operating costs
