Abstract |
The Closed vessel (CV) is an equipment used to study the ballistic parameters by
recording burning time history, pressure buildup during the process and vivacity of the propellants.
It consists of strong pressure vessel, piezo-electric pressure transducers, sensors and dedicated
software. To save time and resources this method is employed instead of dynamic firing while
doing research and development of propellants. A measured amount of propellant charge is loaded
in the vessel and fired remotely. Ignition is provided by the filament which ignites the black powder
charge. In this study, we have used Closed Vessel Tests (CVT) for the first time for recording the
ballistic parameters of slow burning composite rocket propellant. We developed a set of composite
solid propellant samples containing a mixture of bimodal Ammonium Perchlorate (AP) as an
oxidizer, Hydroxy-terminated Polybutadiene (HTPB) as a binder as well as fuel, Dioctyl Sebacate
(DOS) as plasticizer, 1-(2-methyl) Aziridinyl P
