The Comparation Of Two LAPAN'S Propellants Of Different Composition

This paper compares two LAPAN's propellant compositions. The A propellant ha s a composition of AP/AL/Binder with ratio of 70/10/20 , and propellant B ha s ratio 75/7.5/17.5 , both with HTPB base but different curing agent. As comparator of this simulation is RX-1512.01 rocket that has flight tested. The performances which compared are specific impulse and efficiency characteristic. Result shows that the propellant B gives higher specific impulse, however higher losses is, about 5.373%. One to be considered is that the propellant B produce combustion temperature higher than propellant A by ± 200 K, that may influence the rocket structures.
