Abstract

In this work, a wind tunnel is used to test two scale models of the Tupolev Tu-144 and Concorde at varying Reynolds numbers and angles of attack (AOA). The Concorde’s delta wing design made it perform well in subsonic and supersonic flights due to its high lift-to-drag ratios, efficient vortex flow, and consistent performance up to 25 deg AOA. The design’s limitations in high circumstances were demonstrated by the drag superiority stalling that occurred beyond 25 degrees. Even though it was designed to be supersonic, the Tupolev Tu-144 experienced tremendous drag and very little lift at lower air-to-air altitudes (AOAs) due to flow separation and turbulence. The Concorde has stronger aerodynamics and can adapt to several flight regimes, while the TU-144 can only fly supersonic, according to the research. Aerodynamic designers can use Concorde-inspired active flow control systems, morphing wings, and lightweight materials to maximize lift generation, drag reduction, and efficiency. This study lays the groundwork for future supersonic transport systems that maximize high-speed performance and operational and environmental sustainability.
