What does it take to fly faster than five times the speed of sound? Hypersonic propulsion explores the technologies that make sustained Mach 5+ flight possible-where extreme heat, crushing aerodynamic forces, and radical design challenges converge. This book offers a comprehensive journey through the field, from its historical milestones to the cutting-edge programs shaping the future of aerospace. Readers will find clear explanations of hypersonic aerodynamics, the physics of high-speed flows, and the propulsion systems-ramjets, scramjets, and hybrids-that drive these extraordinary vehicles....
