On scaling relations for hypervelocity electromagnetic launch processes
conference paper
In this paper, a set of fundamental scaling relations for hypervelocity electromagnetic launch processes is presented. These relations are based on the electrical circuit equations, the magnetic and heat diffusion equations, the equation of motion and the constitutive equations. The analysis includes Joule heating and frictional heating as source terms for the heat diffusion equation and temperature-dependent material properties. The feasibility of scaling and its consequences are discussed in terms of scaleable and non-scaleable aspects. The scaling relations derived provide the guidelines for performing scaled experiments. Examples of lumped parameter and finite element simulations of full scale and small scale hypervelocity launch experiments are presented.
