The focus of the internship has been on two topics: a) Characterize the drilling performance of a novel percussive augmenter – this drill was developed by the JPL’s Advanced Technologies Group and its performance was characterized; and b) Examine the feasibility of striking a pipe as a means of assessing the water height inside the pipe. The purpose of this investigation is to examine the possibility of using a simple method of applying impacts to a pipe wall and determining the water height from the sonic characteristic differences including damping, resonance frequencies, etc. Due to multiple variables that are relevant to fluctuations in measurement, creating a program through the software MatLab has been the most effective approach to analyzing the recording of the impacts signatures. The software that is being developed is intended to enable clear distinction at various water levels and if it is determined to be a practical tool the technique will be implemented to operating at an industrial setting.
