Designers ordinarily try to improve them by simplifying in order to reduce the cost payload launches. They are very exceedingly complex and generally very expensive to build. However, there has been little or no significant progress in their basic data. While, MDB based on AP/Al were found to be more energetic with an increase in calorific value to reference formulation using bomb calorimetery they exhibited good thermal stability in terms of ignition temperature using cook off test, and accepted thermal behavior using DSC.Ĭonventional modern rocket has existed for more than a half century. Accordingly, the combustion reaction could proceed faster. Consequently, it could alter the combustion mechanism, by thinning the induction zone, allowing the luminous flame zone to be more adjacent to the burning surface. Aluminum metal fuel offered an increase the combustion temperature, and propellant thermal conductivity. The partial replacement of AP with aluminum metal fuel demonstrated a positive impact on both the burning rate and C ⁄. The two potential oxidizers KP and AP exhibited controversy effects whereas KP positively impact the burning rate, AP positively impact C ⁄. The impact of these energetic additives on burning rate and the characteristic exhaust velocity of gaseous product (C ⁄) were evaluated using small-scale ballistic evaluation test motor. This study reports on, the impact of potential oxidizers including potassium perchlorate (KP) and ammonium per-chlorate (AP) on combustion characteristics of double base (DB) propellant. One of the main approaches for the development of MDB propellant is the integration of potential oxidizers and metal fuels. Much attention has been directed toward the development of modified double base (MDB) propellant as it can offer high specific impulse as well as wide range of burning rate.
