Design Analysis of Medium Form Factor Stealth UAVs with Variable-Sweep Wings for ISR Missions Utilizing Advanced Composite Materials for Radar Absorption

UAV technology has advanced due to the increasing demand for low observable, highly capable platforms in Intelligence, Surveillance, and Reconnaissance (ISR) missions. The design and study of a medium sized UAV with variable sweep wing technology and modern composite materials tuned for radar absorption are presented in this paper. The suggested UAV addresses the difficulties encountered in modern ISR operations by combining stealth, aerodynamic efficiency, and mission adaptability. Variable sweep wings improve performance in both high speed, long endurance missions and low-speed, high-maneuverability operations by enabling dynamic adaptability to various flying regimes. The incorporation of sophisticated composite materials, such as graphene-infused laminates and carbon fiber reinforced polymers, results in improved strength-to-weight ratios and a decrease in radar cross section. To guarantee structural integrity and aerodynamic stability, CFD and FEA are used to improve the wing structure and sweep mechanism. By reducing acoustic and infrared signatues, a low noise Electric ducted fan propulsion system is used to further improve the UAV's stealth capabilities. The propulsion and wing designs are integrated to achieve seamless performance while maintaining a streamlined profile. Radar absorbing coatings and interior cargo compartments are used to guarantee the effectiveness of the mission and minimize detectability. The system architecture of the UAV will be described in the study, along with modular payload variants, thermal management techniques, and stealth design concerns. The proposed research aims to design and analyze a medium form factor UAV with variable sweep wings and advanced composite materials for stealth applications in ISR missions. Preliminary testing and future simulations will be focused on verifying the UAV's functionality, particularly its capacity to function well in ISR missions with little observability. The findings will direct iterative enhancements to guarantee the UAV satisfies performance and stealth standards in a range of operating situations. By improving UAV design and technology, this project should offer a scalable solution for ISR operations in contested situations. In order to meet the demands of contemporary aerospace applications, the research will aid in the development of advanced UAV systems that can operate at high performance levels with minimal detectability.
