MRI: Acquisition of High Speed Video Imaging System for Electromagnetic Shockwave Control and Shockwave-Boundary Layer Interaction Research at AAMU

1337227本方案的目标是为阿拉巴马州农工大学(AAMU)的马赫4超音速风洞购买高速视频成像系统。成像系统将使研究人员能够进行电磁冲击波控制和冲击波/边界层相互作用研究，这两项都需要捕获冲击波在极端热通量区域附近的位置和运动，在极端热通量区域，冲击波通常以1千赫到20千赫的频率振荡。AAMU超音速风洞是用于冲击波实验的最先进的设备。该风洞装置可以在6x6x18英寸的试验段内以4马赫的速度提供20秒的稳定空气。现有的风洞仪器包括STING天平、光学成像纹影系统和48个通道的计算机控制高速数据采集系统。然而，该风洞系统不具备任何高速成像能力，这是超音速激波干扰研究的关键。拟议中的项目将获得Vision Research制造的高速高分辨率数字视频系统Phantom V1210摄像机。它是超音速风洞设备的必备仪器。这将立即使利用AAMU-S超音速风洞进行激波和激波-边界层干扰的电磁控制研究成为可能。

1337227DengThe objective of this proposal is to acquire a high-speed video imaging system for the Mach 4 supersonic wind tunnel at Alabama A&M University (AAMU). The imaging system will enable researchers to conduct electromagnetic shockwave control and shockwave/boundary layer interaction research, both require capturing the shockwave location and movement near the area of extreme heat fluxes where the shockwave is typically oscillating at 1kHz to 20 kHz frequency. The AAMU supersonic wind tunnel is a state-of-the-art facility for shockwave experiments. This wind tunnel facility can provide stable air at speed of Mach 4 for 20 seconds within 6x6x18 inch test section. The existing instrumentation for the wind tunnel includes a sting balance, an optical imaging Schlieren system and a computer controlled high speed data acquisition system with 48 channels. However, this wind tunnel system does not have any high speed imaging capability, which is critical to the supersonic shockwave interaction research. The proposed project will acquire a high-speed high-resolution digital video system, the Phantom V1210 camera, made by Vision Research. It is the necessary instrument for the supersonic wind tunnel facility. It will immediately enable the research in electromagnetic control of shockwave and shockwave-boundary layer interaction using AAMU?s Supersonic wind tunnel.
