Thermal Structural Design Aspects of Military Aircraft

This study presentsthe thermal-structural design aspects of military aircraft, exploring key components such as the evolution of fighters, high-temperature effects, airframe construction, and the role of thermal structural tests. From the early days of flight to the present day, the pursuit of supersonic flight has reshaped aviation, defining new thresholds for speed, agility, and combat capability. As known, high-temperature effects in airframeshave been a substantial focus, with researchers and engineers grappling with challenges such as materialdegradation andthermal fatigue cracks resultingfrom elevated temperatures. The study emphasizes the pivotal role of materials capable of withstanding demanding extreme thermal environments, essential for ensuring the structural integrity and functionality of advanced aerial vehicles. Airframe construction of aircraft stands at the intersection of combat demands and cutting-edge technology, requiring innovative design solutions to address thermal stresses arising from sudden temperature changes. Furthermore, the study highlights the significance of thermal structural tests in validating designs and ensuring the safety, reliability, and performance of aircraft. Through an exploration of these crucial aspects, the study contributes to the broader understanding of the complex interplay between design, materials, construction, and testing in the thermal-structural design of military aircraft.
