Raw Data
; Aerotech E18 RASP.ENG file made from NAR published data
; File produced July 4, 2000
; Submitted to ThrustCurve.org by Chris Kobel (3/29/07)
; 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.
