Feasibility Study for the Use of an Electromagnetic Rail Gun in the Launching and Sustaining of Reentry Models
Abstract
The requirements of a realistic reentry test facility for aerothermodynamic tests are reviewed. Basically, this requires the test article to be accelerated to a high velocity and then exposed to the test environment for a sufficient length of time. One method which might be considered to accelerate the test model to the required velocity is an electromagnetic launcher. Equations are developed to describe the performance of several variations of an electromagnetic launcher, as well as component specifications and approximate costs. A similar effort is devoted to the problem of sustaining the velocity by electromagnetically providing a force to overcome the aerodynamic drag and friction forces during testing. Component specifications are developed and costs are estimated.
