The non-woven felt known commercially as Dyneema Fraglight has an outstanding performances stopping fragments. The objective of this project is to understand the reason for this performance by means of four different approaches: 1) Through mechanical characterization varying size, direction, temperature and strain rate of specimens; 2) Ballistic characterization to obtain residual velocity curves and high speed photography; 3) Numerical simulations of static and ballistic tests; 4) Analytical modeling. All ...
This report investigates I dimensional and 2 dimensional hall effect thruster models to better understand the following physics related issues: radial structure of the plasma, lateral wall effects, physics of the subsonic region, no near-total ionization regimes, effects of secondary electron emission from the walls, and reduction of the growth rate of self oscillations.
