Application, development, and challenges of stealth materials/structures in next-generation aviation equipment

Accessing the electromagnetic spectrum is the essence of modern warfare, which is determined by the detection direction, the airframe structure, and the material. Modern aviation equipment with a long strike range, penetration, and strong sensing and rapid decision-making capabilities is the key to capturing spectrum access. The development of penetration detection can promote the application of stealth materials/structures in next-generation aviation equipment, though the design of component-level stealth structures is constrained by aerodynamic efficiency, maneuverability, and preparation processes. Panel-level stealth material/structure design provides new avenues for the development of next-generation aviation equipment. This paper reviews the key advances and future challenges for stealth materials/structures. The main content focuses on the detection technology and application of stealth materials/structures in aviation equipment and the challenges posed by stealth materials/structures in terms of aviation equipment maintenance. Furthermore, this study addresses the opportunities and development tendencies of stealth materials/structures.
