Launch Dynamics of Supersonic Projectiles

Determining the Position and Trajectory of Supersonic Projectiles from Acoustic Measurements

Locating the trajectory of an incoming projectile has important military and civilian applications. The origin of the trajectory can be used to locate sniper fire, and the end-point can be used to determine target hit coordinates on appropriately instrumented target ranges used by armed forces as well as civilian agencies (police and sports). Such non-contact determination of hit coordinates ca...

Simulation of Launch Vehicle Dynamics on an Interstage Structure

Flying a rover from low earth orbit to the surface of the moon requires an interstage structure. This interstage structure serves two main purposes: to contain the rocket motors used for trans lunar injection and braking, and to support the lander and rover inside the launch vehicle payload fairing. The interstage is subject to various forces imposed by the launch vehicle, and must be designed ...

Dynamics of a supersonic plume moving along a magnetized plasma.

A particle-in-cell code is used to investigate the evolution of a density plume moving through a background plasma with supersonic speed directed along the confinement magnetic field. For scale lengths representative of laboratory and auroral phenomena, the major nonlinear effects identified by the present simulations are the formation of a bipolar current system from the ballistic electrons, t...
