Abstract:

A model of the Improved Tartar missile motor was tested to determine the effect of internal geometry on the acoustic losses by axial mode oscillations. Use of coldflow techniques and interchangeable model parts allowed tests to be run on more than 250 internal geometries. Acoustic loss data as a function of internal geometry is presented. It is believed that the testing methods developed in conjunction with this problem are generally applicable and provide a valuable design tool for future motor acoustic problems. Author
