“…It is believed that this was a result of soot buildup caused primarily by insulator erosion [2]. This internal shorting resulted in an additional 7 shots being degraded substantially below average performance (peak current < 200 kA).…”

Electromagnetic launcher (EML) performance repeatability has been identified as a potential development issue for severa1 years. Investigation of this issue has been difficult since an EML that is powered on a relatively continuous basis to provide long duration operation has not been available. A battery charged capacitor power system has enabled long duration, six to seven seconds, EML experiments. This paper provides a summary of an experiment to investigate EML launch-to-launch performance consistency. A series of 8 ten shot bursts each separated by 15 to 30 minutes was performed in one day using a single set of bore materials. The experiment set-up is described, the experimental results discussed, and key parameters which could affect performance repeatability are identified,.

“…Some equations and relationships can also be scaled using this method. For example, Ohm's law can be written as (2) As such, Delta scaled variables behave as if they have units even though they are unitless. This provides a way to check for consistency in scaling laws by making sure the dimensions of the equations agree.…”

When it comes to scaling rail guns, there is no best or one-size-fits-all methodology. It is important for the researcher to be able to choose the appropriate scaling methods to best match the application in an experiment. This paper is an overview of railgun scaling methods; the generic railgun equations are tailored to obtain suitable methods for applications involving circuits, kinematics, fields, thermal control, and mechanics. These methods can be applied to the power supply of the gun, the gun itself, or both depending on the nature of the investigation. The scaling methods of previous literature are reviewed and expanded upon, and scaling based on circuit modeling is presented and simulated.
