Abstract:

The electrothermal accelerator ET gun is advanced propulsion technique in which an electrically generated high temperature, high pressure plasma interacts with a working fluid to produce the gases necessary to accelerate a projectile. In the development of ET technology, the characterization of the temperature and pressures generated by this plasma is critical for modeling of the ET process and ultimately, complete understanding of a fielded weapon system. The results are reported here of an experimental effort aimed at determining the temperature of ET plasmas using atomic emission spectroscopy. The ultimate goal of this work is to develop a technique at the benchtop level that will be directly transferable to measuring the temperature in a large scale ET gun.
