NASA is preparing to 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. The shock-sensing probe, developed by researchers at NASA’s Armstrong Flight Research Center in California, will capture precise pressure data during supersonic flight to validate computer models predicting the strength of the shock waves produced by the X-59.
The probe will be attached to an F-15B aircraft during test flights, flying close behind the X-59 to collect data on air pressure changes as it flies through shock waves. The near-field probe, optimized for capturing shock waves close to the aircraft, will be tested to evaluate upgrades that improve accuracy and recording time. The mid-field probe will collect data at different altitudes to better understand shock wave characteristics.
The probes have been designed with five pressure ports to measure static pressure changes as the X-59 flies through shock waves, providing researchers with valuable data to improve their computer models. Upgrades to the probe include placing pressure transducers closer to the ports and implementing a heating system to maintain accuracy in changing conditions.
NASA Principal Investigator Mike Frederick stated that the probes will meet the resolution and accuracy requirements for the Quesst mission, showcasing how NASA can adapt existing technology to solve new challenges. The advancements made on these probes will play a crucial role in the development of the X-59 and its ability to reduce loud sonic booms to quieter sonic thumps during supersonic flight.
