XLCB: A New Closed-Bomb Data Acquisition and Reduction Program
Abstract
A new closed-bomb data acquisition and reduction program has been developed based on the Microsoft Excel 97 spreadsheet platform. With the addition of IOTech's Wavebook/512 data acquisition hardware, the voltage signal from the closed-bomb experiment is directly captured into the spreadsheet where burning rate (BR) calculations can be performed. Additionally, XLCB has the capability to generate pressure vs. time data based on given BRs, geometrical form, and propellant thermochemistry. A proposed summary sheet is included to better facilitate the exchange of information between interested parties in the propellant community. The Visual BASIC code used in this program was adapted from the FORIRAN algorithms in BRLCB with some additional improvements/modifications. The implementation of a user-friendly interface, the technique used to calculate the derivative, and the comparison of the normalized surface area and vivacity profile are some of the more dramatic changes. Multiple fits of the BR law (A(*)Pn) using different pressure regimes can be graphically chosen from either the BR vs. pressure graph or the vivacity graph.
