Abstract:

Complex aerodynamic processes like Shock Wave Boundary Layer Interaction (SWBLI) affect hypersonic vehicle efficiency and safety. This comprehensive research examines SWBLI's effects on hypersonic aerofoil performance, revealing new causes and mitigating methods. This study begins with SWBLI concepts and how the boundary layer moves with flow and compression shock waves interacting with the aerofoil. We concentrate on crucial techniques for surprise wave diffraction, reflected image, and turbulent boundary layer interaction on hypersonic aerofoils. Research simulates SWBLI incidents using turbulence models and sophisticated CFD. Experimental validation and computational device enhancement are needed to forecast SWBLI impacts. Hypersonic centers and wind tunnel tests for SWBLI dynamics research are discussed. The methods and equipment shown here measure SWBLI's aerodynamic and thermal effects experimentally. We examine how SWBLI affects hypersonic aerofoil lift, drag, pitching second, and heat transfer. SWBLI-induced aerodynamic instabilities and thermal stresses require unique mitigation approaches, according to the study. We study boundary layer suction, plasma actuators, and floor changes to improve SWBLI aerofoil stability and performance. Advanced fabrics, coatings, and thermal protection reduce SWBLI. Hypersonic aerofoil programs need structural design optimization and balancing analysis due to SWBLI aeroelasticity and structural reactivity. The paper uses case studies and programs to demonstrate SWBLI control in hypersonic car design, providing aerospace industry and research insights. The research recommends teamwork and innovation to overcome SWBLI effects on hypersonic aerofoil performance.
