Flashcards
Supersonic Speed
Supersonic Speed
The speed of an object that is faster than the speed of sound. Typically around 768 mph (1,236 km/h).
Sonic Boom
Sonic Boom
The loud, intense sound produced when an aircraft breaks the sound barrier. It can be damaging and disruptive.
X-59
X-59
NASA's innovative aircraft designed to fly at supersonic speeds without producing a sonic boom. It aims to revolutionize air travel.

Study Notes
NASA's X-59 Quiet Supersonic Aircraft
- NASA's X-59 aircraft, unveiled in 2024, aims to revolutionize supersonic travel.
- It's part of the QueSST (Quiet SuperSonic Technology) mission.
- The goal is to achieve supersonic speeds (faster than the speed of sound, ~768 mph / 1,236 km/h) without the sonic boom.
- Peter Coen, the QueSST mission manager, emphasized making air travel twice as fast, while remaining safe, sustainable, and quieter.
- Previous supersonic aircraft, like the Concorde, were limited by sonic boom, impacting noise pollution and flight routes.
- Sonic booms create a disturbance when an aircraft breaks the sound barrier and cause significant noise, potentially damaging buildings.
X-59 Design Features for Quiet Supersonic Flight
- The X-59's unique design is key to reducing the sonic boom.
- Its long, pointed nose helps break up shock waves.
- The removal of the forward-facing cockpit window reduces shock wave effects.
- Advanced cameras are used instead of the traditional cockpit view, allowing pilots to maneuver safely.
- The engine is positioned on top to direct noise away from the ground.
