A far-field repetitive pulse laser thruster
説明
The pressure wave expansion around a laser-induced plasma was investigated by experiments and numerical simulations as part of the on-going research of repetitive-pulse laser thrusters. In the experiments, pressure fields around the plasma called a "fire-ball" were measured. The thrust impulse was numerically estimated from the measured pressure profiles assuming a simple fire-ball expansion. As a result, a maximum impulse of l.lmNs was obtained by a pressure-receiver located at 21 mm apart from the center of expansion with an input energy of 1J. Since this optimum receiver location is far enough from the fire-ball, the heat conduction to the receiver can be neglected in a so-called "far-field thruster."
