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

Abstract

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.
