Data Reduction Procedure for an Experimental Method of Measuring the Velocity-Coupled Response Function of Solid Propellants

<p>A computer program has been developed for calculation of the velocity-coupled response function of solid-propellants from experimentally measured pressure data. The proposed velocity-coupled response function measurement apparatus consists of an end-burner combustor where the propellant sample is oscillated in a direction normal to the flow in the presence of a standing acoustic wave within the combustion chamber. The pressure measurements are made at select points along the length of the chamber.</p> <p>The data reduction program consists of a Runge-Kutta routine driven by a BFGS multivariable search routine. The Runge-Kutta routine determines the pressure distribution within the chamber of the proposed apparatus for a specific velocity-coupled response function (Rv). The BFGS optimization routine searches for the Rv which minimizes the difference between the calculated and measured pressure distributions.</p> <p>The data reduction program has demonstrated convergence to the proper Rv value for pressure data that was generated by sampling from gaussian distributions.</p>
