Show moreExperiments are conducted to investigate the ability of variable pressure, pulsed-blowing actuators and zero-net-mass-flux actuators to maintain a constant lift force on a low aspect ratio, semi-circular wing in a longitudinally gusting flow. Dynamic models of the lift response to actuation and the lift response to longitudinal gusting are obtained through modern black-box system identification methods. Robust, H∞, closed-loop controllers are synthesized using a mixed sensitivity, loopshaping approach. An additional feed-forward disturbance compensator is designed based on a model of the unsteady aerodynamics. The controllers show suppression of lift fluctuations at low gust frequencies, f < 1Hz (reduced frequency, k < 0.09). At higher frequencies, the control performance degrades due to limitations related to the time for a disturbance, created by the actuators, to convect over the wing and establish the flow field that leads to enhanced lift on the wing. Similar limitations are observed for both wings even though the bandwidth of the zero-net-mass-flux actuators is an order of magnitude higher than that of the pulsed-blowing actuators.

Show moreThis objective of this IPRO is to develop devices to aid visually impaired persons swim. The team has chosen to work on two separate devices to accomplish this task. One approach is to use a passive device, which is located in the pool, to guide the swimmers through the lane. A picture of the latest version of the device is pictured below in figure 1 with several key features identified.

Show moreThe purpose of this IPRO is to develop a robust, working prototype that can automatically monitor and detect a problem with a milling machine at A. FInkl & Sons Co. This IPRO is in its fourth semester and there are two challenges remaining: (1) alerting management to the detection of broken teeth during machining; and (2) developing spatial representations of items undergoing heat treatment. However, A. Finkl & Sons has asked us to concentrate solely on the goal of finding a way to detect when a break occurs in one of the milling teeth and then alert the mechanic monitoring the machine in order to replace it. This system will involve measuring vibrations using an accelerometer or by the use of laser detection. The goal of this IPRO is to research, test, and inform A. FInkl & Sons of the best solution to invest in, therefore they can decide what is better for their company.
