摘要

In air-breathing engines, ramjet is dominated due to their higher specific impulse which is higher than rocket engine as well. Because of that, ramjet has been used for medium and high supersonic speed missiles to achieve longer range and endurance [1]. Various modifications have been done in ramjet engines to enhance their ballistic properties. These modifications are realized by changing in working substance (fuels/propellants) as well as internal designs. Among various types of ramjet engines, solid fuel ducted rocket (SFDR) is one which produces higher specific thrust [1, 2]. Therefore, SFDR is considered as an alternative propulsion system to rockets as a means to flying through the atmosphere. Actually, SFDR has two combustion chambers: primary and secondary. In primary combustor (or gas generator), solid fuel/propellant burns and generates fuel-rich high-pressure and high-temperature gas which moves into the secondary combustor and burns further with shock-induced compressed air [3].
