“…Compared with micro‐sinusoidal pressure standard [2], sinusoidal pressure standard [2, 3], and quick‐opening valve dynamic pressure standard [2], shock tube‐based dynamic pressure standard [4, 5] was chosen because its range of step pressure covered most of the dynamic pressure transducers' measuring range in CARDC. The performance index of shock tube‐based dynamic pressure standard [6]: the range of the step pressure should be 15 kPa–1 MPa; the rise time of the step pressure should be <1 μs; the duration of the step pressure plateau should be >4 ms; the fluctuation of the step pressure plateau should be within ± 2%; the second ‐ order expand uncertainty of the step pressure should be <4%.…”

“…Shock tube was used for the calibration of dynamic pressure transducers because it was an ideal generator of step pressure [3][4][5][6]. According to the 'Verification Regulation of Dynamic Pressure standards' [7], the shock tube based dynamic pressure standard should meet all demand of performance index showed in table 1. order expand uncertainty of the step pressure generated by the calibration installation was specially studied.…”

Abstract. The step pressure generated by shock tube was used for calibration of dynamic pressure transducers. First, the performance of the shock tube based calibration installation was theoretically predicted. The influence of Mach number to the step pressure and the duration of the step pressure plateau was analyzed by numerical calculation. Second, the performance of the calibration installation was tested, whose result showed that the minimum and maximum value of the step pressure generated by the calibration installation was 9.60kPa and 1.101MPa, respectively, the maximum value of the rise time of the step pressure was 0.7μs, the minimum value of the duration of the step pressure plateau was 4.14ms, the fluctuation of the step pressure plateau was better than ±2%, and the maximum value of the 2 nd order expand uncertainty of the step pressure was 3.52%. The test result verified that the calibration installation met the requirements of the previous design and correlative verification regulations. Last, the sensitivity and syntonic frequency of standard pressure transducers were tested by the calibration installation. The result was in accord with the factory technical parameters.

“…Pressure sensors have been widely used to measure dynamic pressure signals in intelligent control, wind tunnel test, flight test, and so on [ 1 ]. The dynamic performance parameters of a pressure sensor are the important indicators of its dynamic measurement capability and are also the main basis to judge whether the needs of a dynamic pressure measurement are met [ 1 , 2 ].…”

“…Since the shock tube was created in 20th century, it has been widely used in a variety of dynamic experiments. A shock tube can produce a high-speed shock wave and a subsequent step pressure, making it ideal dynamic equipment for calibrating pressure sensors [ 1 ]. In 2002, the Instrument Society of America published an important work titled “A Guide for the Dynamic Calibration of Pressure Transducers”, which considered shock tube calibration as the most important calibration methods [ 2 ].…”

Dynamic calibration is one of the important ways to acquire the dynamic performance parameters of a pressure sensor. This research focuses on the processing method for the output of calibrated pressure sensor, and mainly attempts to solve the problem of extracting the true information of step response under strong interference noise. A dynamic calibration system based on a shock tube is established to excite the time-domain response signal of a calibrated pressure sensor. A key processing on difference modeling is applied for the obtained signal, and several generating sequences are established. A fusion process for the generating sequences is then undertaken, and the true information of the step response of the calibrated pressure sensor can be obtained. Finally, by implementing the common QR decomposition method to deal with the true information, a dynamic model characterizing the dynamic performance of the calibrated pressure sensor is established. A typical pressure sensor was used to perform calibration tests and a frequency-domain experiment for the sensor was also conducted. Results show that the proposed method could effectively filter strong interference noise in the output of the sensor and the corresponding dynamic model could effectively characterize the dynamic performance of the pressure sensor.
