<comments>Estes B4 RASP.ENG file made from NAR published data
|
|
File produced October 3, 2000
|
|
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.
