Advanced Pressure Sensors for Aerodynamic & Aero-acoustics Testing
12/08/2024
The study of aerodynamics and aero-acoustics requires specialized sensors to obtain accurate measurements. PCB Piezotronics and Endevco, renowned brands in the field of measurement, offer a comprehensive portfolio of high-performance sensors and measurement equipment to meet these specific needs.
The technical differences between aerodynamics and aeroacoustics lie in the types of measurements and sensors used in each field. In aerodynamics, the emphasis is on obtaining precise measurements of forces, pressures, velocities, and flow patterns. To achieve this, various sensors are employed, such as dynamic ICP pressure sensors, piezoresistive pressure sensors, and piezoelectric ICP force sensors. These sensors provide valuable data on static and dynamic pressure distributions, enabling researchers to understand the aerodynamic behavior of objects in different conditions.
Aeroacoustics, on the other hand, requires sensors capable of capturing sound waves and small pressure fluctuations with high resolution. In this field, piezoelectric microphones, piezoelectric acoustic pressure sensors, and prepolarized microphones are commonly used. These sensors excel at measuring highintensity acoustic noise and low-pressure fluctuations in harsh environments. They are designed to capture transient pressure events, air turbulence, and other acoustic phenomena associated with aircraft structures, rockets, or aerodynamic models.
While there is some overlap in the sensor technologies used for aerodynamics and aeroacoustics, the specific focus and measurements differ. Aerodynamics concentrates on the forces and flow characteristics, requiring sensors that provide detailed information about pressures and velocities. In contrast, aeroacoustics focuses on noise generation and propagation, necessitating sensors specialized in capturing sound waves and low-pressure fluctuations. By installing the appropriate sensors for each discipline, researchers can gain a deeper understanding of both the fluid dynamics and acoustic aspects associated with objects moving through the air.
