Animal Motor Works K1075 RASP.ENG file made from NAR data File produced Feb 22, 2003 The total impulse, peak thrust, average thrust and burn time are the same as the averaged static test data on the NAR web site in the certification file. The curve drawn with these data points is as close to the certification curve as can be with such a limited number of points (32) allowed with wRASP up to v1.6.
