Introduction to High-Speed Aerodynamics and Compressible Flow

High-speed flight changes everything we know about fluid dynamics, as air compresses and shock waves form around a vehicle. Understanding these compressible flow phenomena is essential for anyone designing or analyzing modern aircraft, projectiles, or spacecraft. This course guides you from the fundamental physics of gas dynamics to the practical equations used to analyze supersonic and subsonic flows. You will learn to predict shock wave behavior, calculate lift and drag at high speeds, and understand modern aerodynamic modeling techniques. What you'll learn: - Understand the core principles of compressible flow and thermodynamic relations - Analyze normal and oblique shock waves in high-speed flight regimes - Calculate expansion waves and supersonic flow behavior over aerodynamic surfaces - Apply quasi-one-dimensional flow equations to nozzles and diffusers - Explore modern computational fluid dynamics (CFD) considerations for high-speed simulation - Evaluate aerodynamic performance and wave drag in supersonic aircraft design Starting with foundational definitions of the speed of sound and Mach number, this text-based course progresses systematically through shock theory, expansion waves, and nozzle flows, concluding with an introduction to modern digital simulation workflows. Designed for engineering students, aerospace enthusiasts, and beginners, this course requires no advanced prior coursework. Start reading today to unlock the principles governing supersonic flight.
