NASA is preparing to test advancements on a key tool for measuring the sonic thumps generated by its quiet supersonic X-59 research aircraft. The shock-sensing probe, developed by researchers at NASA’s Armstrong Flight Research Center, will collect precise pressure data during supersonic flight. This data will be essential for validating computer models that predict the strength of shock waves produced by the X-59.
The probe consists of two versions optimized for near-field and mid-field measurements, capturing shock waves close to the aircraft and at altitudes between 5,000 to 20,000 feet. An F-15B aircraft will fly with the X-59, equipped with the probe to collect pressure data during test flights.
The probe’s design includes five pressure ports that calculate local pressure, speed, and airflow direction through the shock waves. NASA’s principal investigator for the probe, Mike Frederick, stated that the probe will act as a “truth source” by comparing predicted data with real-world measurements.
Upgrades to the near-field probe, including closer positioning of pressure transducers and a heating system for temperature control, will soon be evaluated through test flights. These upgrades aim to improve the probe’s accuracy and resolution to meet the requirements of the Quesst mission.
Overall, this project showcases NASA’s ability to adapt existing technology to address new challenges in supersonic flight research. The data collected by the shock-sensing probe will be crucial for advancing the development of quieter supersonic aircraft in the future.
