Zusammenfassung: | The invention discloses a porous array optical fiber probe for multidirectional high-speed dynamic pressure measurement and a measurement system thereof. The probe comprises a probe, a pressure sensing diaphragm, an optical fiber fixing device and a plurality of optical fibers, wherein a conical structure is formed at the upper end of the probe; the optical fiber fixing device is a cylinder, and the upper end of the optical fiber fixing device is connected below the probe; the pressure sensing diaphragm is arranged between the probe and the optical fiber fixing device; metal protective coversare packaged on the outer surfaces of the optical fiber fixing device and the probe; the optical fiber probe is fixed on the inner wall of an engine through a support, and an optical fiber of the optical fiber probe penetrates through the support and is connected with a high-speed demodulator to form a measurement system. According to the invention, multi-channel and multi-direction pressure measurement can be carried out |
