NASA’s X-59 Completes ‘Cruise Control’ Engine Speed Hold Test

The team behind NASA’s X-59 completed another critical ground test in March, ensuring the quiet supersonic aircraft will be able to maintain a specific speed during operation. The test, known as engine speed hold, is the latest marker of progress as the X-59 nears first flight this year. “Engine speed hold is essentially the aircraft’s […]

NASA to Test Technology for X-59’s Unique Shock Wave Measurements

NASA will soon test advancements made on a key tool for measuring the unique “sonic thumps” that its quiet supersonic X-59 research aircraft will make while flying. A shock-sensing probe is a cone-shaped air data probe developed with specific features to capture the unique shock waves the X-59 will produce.

NASA Instruments Will Listen for Supersonic X-59’s Quiet ‘Thump’

NASA’s X-59 experimental aircraft is unique – it’s designed to fly faster than the speed of sound, but without causing a loud sonic boom. To confirm the X-59’s ability to fly supersonic while only producing quiet sonic “thumps,” NASA needs to be able to record these sounds from the ground. The agency recently completed tests […]
