THE ARC JET AS A MEANS OF PRODUCING FULL TEMPERATURE SIMULATION IN A HYPERSONIC WIND TUNNEL (APPLICATION OF A CROSSED FIELD ACCELERATOR)
Abstract
The general concept of using crossed electrostatic and magnetic fields to accelerate the flow of an ionized plasma was investigated experimentally and theoretically. The experimental installation consists of the following units: an air-stabilized arc which serves as the plasma generator, an inlet viewing chamber for velocity measurements, the acceleration section, an outlet viewing chamber, the test section with quartz viewing window, and finally the vacuum system. The experimental effort consists in correlating the input and output accelerator velocity and Mach number with the applied electromagnetic fields, mass flow, and gross operating parameters of the installation. The theoretical results of the one-dimensional, steady, compressible flow treatment of the problem are presented. These results are summarized in the form of nondimensional charts which display the role of the relevant nondimensional groups that enter into the interaction. These charts readily establish the performance limits of such an accelerator. (Author)
