Questions & Answers

Q: What is the purpose of NASA's X-59 Quest aircraft?

The X-59 Quest is being developed to enable commercial supersonic flight over land by reducing the noise produced during supersonic flight, using quiet supersonic technology.

Q: How will the X-59 reduce the sonic boom to a sonic thump?

The X-59 is designed with a carefully shaped fuselage, wings, and engines to distribute shock waves in a way that minimizes the loudness of the sonic boom, resulting in a quieter sound perceived on the ground.

Q: What are some characteristics of sound waves?

Sound waves are compression or longitudinal waves created by vibrations. They have characteristics such as wavelength, frequency, and amplitude. The rate of vibration (frequency) determines the pitch, and the amplitude determines the volume of sound.

Q: How do chevrons help reduce noise in jet engines?

Chevrons are noise-reducing technologies used in jet engines. They smooth out turbulence created by the mixing of hot and cold air streams, reducing noise generated by the engines.

Summary & Key Takeaways

• NASA's newest experimental airplane, the X-59 Quest, is being designed with quiet supersonic technology to reduce the noise of sonic booms during flight.

• The X-59 will gather scientifically valid data on community reactions to noise during supersonic flights, which will be used to establish new regulations for commercial supersonic travel over land.

• The X-59 is expected to reduce the perceived noise levels from supersonic flight to around 75 decibels, significantly quieter than traditional supersonic aircraft.
