  • 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][3]
  • Hypersonic flight - Wikipedia
    Hypersonic glide vehicles are typically launched with a ballistic first stage, then deploys wings and switch to hypersonic flight upon re-entering the atmosphere, allowing the final stage to evade missile defense systems that were designed for purely ballistic missiles
  • Hypersonic Weapons Explained: Which Countries Have Them and Why They . . .
    Two types of hypersonic weapons dominate current development: hypersonic glide vehicles (HGVs) and hypersonic cruise missiles (HCMs) They achieve their speed through fundamentally different means, and each presents different challenges for defenders
  • Hypersonics - NASA
    In the field of aerodynamics, hypersonics is generally associated with flight through an atmosphere at speeds in excess of Mach 5, i e five times the local speed of sound
  • Hypersonic Technology Project - NASA
    NASA is working to enable routine, reusable, airbreathing hypersonic flight by conducting fundamental and applied research to enable a broad spectrum of hypersonic systems and missions
  • Hypersonics | Lockheed Martin
    We are developing game-changing hypersonic solutions to ensure our customers are always ready for what’s ahead Traveling at Mach 5 and beyond – more than a mile per second – is the new standard for modern national defense
  • Hypersonic Flight Vehicles – Introduction to Aerospace Flight Vehicles
    Hypersonic vehicles often feature blended bodies with tightly integrated propulsion systems, in stark contrast to the separate airframe-and-engine architectures of subsonic and supersonic aircraft Complex aerodynamics and other issues arise in hypersonic flight
  • Hypersonic breakthrough could enable planes that fly 10 . . . - ScienceDaily
    Hypersonic flight could one day make long-haul travel as quick as a short movie Researchers are testing how turbulence behaves at extreme speeds, a critical hurdle for designing these aircraft
  • 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
  • An Overview of Current U. S. Hypersonic Missile Developments
    These programs focus on conventionally armed hypersonic weapons rather than nuclear payloads, currently in development by some competitors Hypersonic systems operate at speeds above Mach 5 and often maneuver during flight, which makes accurate targeting more difficult
