Standard operational features of the FASTCAM SA-Z include a mechanical shutter to allow remote system calibration, dual-channel Gigabit Ethernet Interface for fast image download, and internal memory card drives allowing image download and storage to low cost removable recording media. Available in 12-bit monochrome or 36-bit color versions with recording memory options from 8GB to 128GB, the FASTCAM SA-Z offers versatility of use in a wide range of scientific and industrial applications. The FASTCAM SA-Z provides frame rates greater than 2.1 million fps at reduced image resolution and shutter speeds as short as 159 nanoseconds (export restrictions may apply).Īn innovative camera body design exploiting heat-pipe technology provides a thermally stable and reliable high-speed imaging system suitable for use in the most challenging environments.
The ultra-high speed FASTCAM SA-Z provides megapixel image resolution at frame rates up to 21,000 frames per second (fps) from its highly light sensitive image sensor (monochrome ISO 50,000) with 12-bit dynamic range delivering the ultimate imaging performance. Using Photron’s proprietary CMOS image sensor technology, the FASTCAM SA-Z combines high recording rates with outstanding light sensitivity and excellent image quality to provide the most versatile ultra-high speed digital camera available today. Moreover, with the decrease of the tube diameter, it can be inferred that the significant increase of the relative heat loss is the main reason for the decrease of the propagation velocity while the dimensionless parameter θ can be used to analyze the heat loss coefficient under different charge diameters.The Photron FASTCAM SA-Z offers scientists, researchers and engineers the ability to capture high resolution digital images at ultra-high speeds to see and understand previously invisible processes and events. This can greatly improve the propagation velocity of Al/CuO nano-thermite under constraint conditions.
Meanwhile, by introducing a certain amount of NC into the component, the reactivity can be improved while the gas production and pressurization capacity can be increased at the same time. Our experiments and theoretical calculation results show that the seepage of the gas flow is an important factor affecting the heat transfer process of Al/CuO nano-thermite in burn tubes, which makes the propagation velocity decrease with the increase of the charge density. The combustion behavior of Al/CuO and Al/ nano-thermites in burn tubes was contrastively investigated by turning the charge density and the tube diameter in the range of 0.8–1.8 g/cm 3 and 0.3–2 mm, respectively. In this paper, to study the propagation behavior and the burning rate enhancement of Al/CuO nano-thermite in confined burn tubes, modification of the component was achieved by introducing energetic binder nitrocellulose (NC).
