Abstract

We report the latest design, fabrication, and characterization result of the Next-Generation Microshutter Arrays (NGMSA) for space borne observatory applications. Our improved blade design aims to reduce the counter torque induced by the potential on the opposing wall to eliminate the torque bump, and thus enables pure electrostatic actuation for more reliable and stable microshutter operations. This paper presents the experimental performances of micro-fabricated microshutter arrays with varying design parameters and compares the results with simulation predictions.

Dynamic Gas Flow Effects on the ESD of Aerospace Vehicle Surfaces

The purpose of this work is to develop a version of Paschen's Law that takes into account the flow of ambient gas past electrode surfaces. Paschen's Law does not consider the flow of gas past an aerospace vehicle, whose surfaces may be triboelectrically charged by dust or ice crystal impingement while traversing the atmosphere. The basic hypothesis of this work is that the number of electron-ion pairs created per unit distance between electrode surfaces is mitigated by the electron-ion pairs removed per unit distance by the flow of gas. The revised theoretical model must be a function of the mean velocity, v (sub xm), of the ambient gas and reduce to Paschen's law when the gas mean velocity, v (sub xm) equals 0. A new theoretical formulation of Paschen's Law, taking into account the Mach number and dynamic pressure, derived by the authors, will be discussed. This equation was evaluated by wind tunnel experimentation whose results were consistent with the model hypothesis.
