Prandtl-Glauert transformation

The Prandtl-Glauert transformation is a mathematical technique used in aerodynamics to analyze how objects behave as they approach the speed of sound, particularly in compressible flows. It helps to relate the characteristics of subsonic (slower than sound) and transonic (approaching sound) speeds by adjusting for changes in air density and pressure. This transformation allows engineers and scientists to predict how aircraft and other objects will perform when they fly at high speeds, ensuring safety and efficiency in design and operation. In essence, it helps bridge the gap in understanding flight dynamics at varied speeds.
