Hypersonic speed - Wikipedia In aerodynamics, hypersonic speed refers to speeds much faster than the speed of sound, usually more than approximately Mach 5 [1][2]
Hypersonic Technology Project - NASA The Hypersonic Technology (HT) Project organizes its work into distinct research topic areas HT explores four key topics in hypersonics: system-level design, analysis, and validation; propulsion technologies, vehicles technologies; and high-temperature, durable materials
Hypersonic Speed Explained: How Hypersonic Planes Work Hypersonic speed is five times the speed of sound Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach Sound has a speed of Mach 1 and anything Mach 5 or above is considered hypersonic
Stevens Researchers Bring Hypersonic Flight One Step Closer to Take Off Hoboken, N J , November 12, 2025 — If it were to become a reality, hypersonic flight, long the realm of science fiction, could revolutionize global travel, transforming day-long international flights into brief commutes no longer than a feature length movie The duration of a long-haul route, such
Research suggests hypersonic flight may not require significant design . . . A new study suggests that aircraft design may not have to be changed drastically for hypersonic flight Air behaves differently around aircraft at low speeds compared to high speeds Air density below 225 miles per hour remains constant This is called incompressible flow and helps simplify aircraft
Japanese Forces Test Deployment of Hypersonic Missile System The Japan Self-Defense Force recently tested the deployment of a developing hypersonic missile system that is designed to defend Tokyo’s islands from foreign warships The Acquisition
