AERODYNAMICS OF HIGH SPEED FLIGHT: BREAKING THE SOUND BARRIER AND THE CHALLENGE OF SUPERSONIC FLIGHT

Abstract

The pursuit of high-speed flight and breaking the sound barrier has been a critical milestone in aerospace engineering. This research investigates the key aerodynamic challenges encountered as aircraft approach and surpass Mach 1, focusing on phenomena such as shock wave formation, wave drag, and the effects of aerodynamic heating. Drawing on experimental data from NASA, ESA, and the German Aerospace Center (DLR), this study examines solutions to these issues, including the implementation of the area rule to reduce wave drag and advancements in thermal protection systems to mitigate aerodynamic heating. Additionally, the paper explores the dynamic stability problems encountered at supersonic speeds and the role of modern control systems, such as fly-by-wire technology, in maintaining aircraft stability during high-speed flight. By reviewing historical achievements, like the X-1 program, and current innovations in materials and control systems, the manuscript highlights the continuous advancements in supersonic flight technology. The findings underscore the importance of collaborative research and technological development in overcoming the sound barrier and propelling future aerospace capabilities toward even higher-speed regimes, including hypersonic flight. The paper concludes by discussing the implications for future aerospace designs and the necessity of further research to address remaining challenges.
