Futuristic Flight The Green Supersonic Machine
Overview • Green Supersonic Machine • Sonic Boom • Conclusion
Green Supersonic Machine • Presented in April 2010 • Plane concept by Lockheed Martin Corporation • 1 of 2 concepts NASA asked for • Also asked Boeing • High altitude • 13,700 to 16,700 meters • High speed • Supersonic (faster than the speed of sound) • From New York to Paris in about three hours → approx. 1,950 km/h • Less than half the time you need today (7.5 hours) • Realistic launch expected between 2030-2035 supersonic(adj.) = Überschall-
How it looks like Long, narrow, aerodynamic shape for high speed and fuel efficiency Inverted-V shaped "spoiler" to reduce the sonic boom
It is designed to be… • quiet • fast (up to nearly 2,000 km/h) • fuel-efficient • able to fly at a high altitude (13,700-16,700 meters) • causing a low sonic boom Wait. Sonic boom? altutude = Höhe
Sonic boom • Also "sonic bang" • Aircraft makes noise • Forwards & backwards • Faster flight → sound waves get compressed • Doppler effect sonic boom = Überschallknall
Sonic boom • Flying faster than speed of sound • > Mach 1 = 1,225 km/h • Aircrafts breaks through "sonic wall" • Sound waves crash into each other, generating an overpressure, noticed as sonic boom Sonic barrier = Schallmauer
Sonic boom • Pressure waves can break glass • Concorde banned from flying over high populated areas • Generated continually, as long as the aircraft is supersonic • Inverted V reduces boom by modifying and softening the pressure
Conclusion • 1 of 2 concepts NASA asked for • Lockheed Martin Corporation • Quiet, fast, high altitude, low sonic boom • Expected launch: 2030-2035 • Sonic boom • Caused by supersonic aircrafts • Sound waves crash into each other, causing an overpressure • Noticed as sonic boom
