摘要

我们描述了一个模拟CMOS VLSI系统，该系统可以处理来自表面安装的剪切应力传感器的实时信号，以检测气流中沿表面的高剪切应力区域。CMOS电路的输出用于驱动微机械襟翼，目的是减少表面上的高剪切应力，从而降低总阻力。我们已经在层流和湍流状态下的风洞中设计、制造和测试了该系统的部分部件。

Analog VLSI system for active drag reduction

We describe an analog CMOS VLSI system that can process real-time signals from surface-mounted shear stress sensors to detect regions of high shear stress along a surface in an airflow. The outputs of the CMOS circuit are used to actuate micromachined flaps with the goal of reducing this high shear stress on the surface and thereby lowering the total drag. We have designed, fabricated, and tested parts of this system in a wind tunnel in laminar and turbulent flow regimes.
