Flashcards
Supersonic speed
Supersonic speed
The speed of an object that is faster than the speed of sound, approximately 768 mph (1,236 km/h).
Sonic boom
Sonic boom
A loud and disruptive noise produced when an aircraft breaks the sound barrier, capable of shaking buildings and even cracking windows.

Study Notes
NASA's X-59 Quiet SuperSonic Technology (QueSST)
- NASA's X-59 aircraft aims to revolutionize supersonic travel, achieving high speeds without sonic booms.
- The QueSST mission seeks to make air travel significantly faster (twice as fast over land) while being safer, more sustainable, and quieter.
- Supersonic speed is any speed faster than the speed of sound, which is approximately 768 mph (1,236 km/h).
- Sonic booms, produced when an aircraft breaks the sound barrier, are disruptive, causing noise pollution and damage to structures.
Design Features of the X-59
- The X-59's unique design minimizes sonic booms.
- Its long, pointed nose disperses shock waves.
- The aircraft's cockpit lacks a forward-facing window, relying on advanced cameras for pilot visibility.
- The engine is positioned above the cockpit and is directed away from the ground, mitigating noise.
Concorde and Supersonic Flight History
- The Concorde, the world's first supersonic passenger jet, faced restrictions on flight paths due to sonic booms.
- Noise limitations confined Concorde flights primarily over oceanic routes.
