Design and Analysis of Artillery Rocket Launcher Tube Mounted on Truck

摘要

© 2022. MechAero Foundation for Technical Research & Education Excellence.The artillery rocket launcher system uses rocket explosives as the projectile mounted on a truck for short and long-range warfare. It consists of a launcher tube in which rockets are loaded which endures very high force, pressure and temperature during the firing of artillery rockets. The study aimed to optimize the artillery rocket launcher tube for geometry, material and cost without compromising the safety and structural stability. The structural and thermal integrity analyses by using the FEA model were performed by considering three thicknesses of the launcher tube viz. 10 mm, 12 mm and 15 mm and three composite materials such as E-glass fiber/epoxy, aramid fiber/epoxy, and carbon fiber/epoxy. The failure analysis of the launcher tube according to the Tsai-Wu failure criterion was obtained from Ansys APDL software. It shows that the maximum value of failure criteria as 0.579 which is less than 1. Overall, the optimum performance artillery rocket launcher tube has been found as the one with E-glass fiber/epoxy composite material with 15 mm thickness.
