Bottom Row - Compound Rocket Projectile Rocket Aerial Ignition Institutional Delay Dynamic Determination Analysis And Modeling

Research on the dynamic delay-time of Hybrid igniting-device in the air is the basis of implementing it's the best trajectory and improving its max cannon-shot denseness.In these dissertation, a theory mathematics model of the dynamic delay-time about Hybrid igniting-device was established, including dynamic "solid-particle" effect model and "particle streamline" effect model of solid power in its igniting delay-time cannulation. At last, drew a conclusion of the theory mathematics model about dynamic delay-time on the sealed condition. As far as the same type of the igniting delay-time cannulation is concerned, there are two main important factors that affect its dynamic delay-time in conclusion: one is the length of the igniting delay-time cannulation; the other is kinetic and directing at burning surface of igniting delay-tune cannulation inner acceleration.At the same time, hi this dissertation, designed the testing system and igniting-device scheme about dynamic testing on the ground, and analyzed possible error produced by theory model, testing system and igniting-device. This is the testing foundation of validating and perfecting the theory model.
