Effect of Dynamic Coupling of Liquid Propellant Sloshing on the Response at Critical Locations of a Typical Liquid Propellant Rocket

Liquid propellant rocket utilizes an engine that uses liquid as a propellant. In rockets, fuel and oxidizer are pumped into the combustion chamber, where they get mixed burned. hydrogen is mainly used fuel, oxygen oxidizer. Slosh can occur with propellants. acts tuned damper helps in reducing dynamic response of vehicle. baffles tanks intelligent control rules guidance system be to this. A potential source disturbance vital stability spacecraft slosh. mechanical model spring-mass-damper commonly represent sloshing dynamics. Modelling typical done MSC NASTRAN / PATRAN software. Dynamic characterization rockets without carried out. Transient analysis on launch vehicles out, responses at critical locations estimated. this project, structural conducted. The main objective project study effect coupling between vehicle modes.
