  • 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]
  • 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 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 Aerodynamics Home - NASA
    Hypersonic aircraft typically have very thick boundary layers along the surface and high heat transfer to the surface All of these high speed flow phenomena lead to a vehicle design unlike the typical airliner or fighter aircraft
  • 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

    Rocket Lab just signed a $190 million contract for 20 hypersonic test launches with a 100% success rate — 7 for 7 at Mach 5+ The tests support the Army's "Dark Eagle" — a Mach 5 missile with 3,500km range that maneuvers through the atmosphere and can't be intercepted by existing defenses
  • New Hypersonic Experiments Confirm a 60-Year-Old Turbulence Theory—and . . .
    New experiments confirm a decades-old theory of turbulence, revealing how air behaves at extreme speeds and shaping the future of hypersonic flight
  • 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
