Abstract

‘Flow Form Tube’, is used as a Casing in various missiles to withstand generated thrust. It encases propellant and plays a vital role in missile thrust technology. The tube is supposed to with stand high temperature and pressures and should have high mechanical properties with more factor of safety. The aim of this work is to study the effect of various parameters like roller radius, stagger, hardness and feed on the final flow formed tube dimensions at different reduction rates on flow forming process of Rocket Motor Tube for various application in aerospace engineering and missile technology. The material chosen for study is MDN 250 (Maraging Steel). Ovality of the tube, Mean diameter, Surface finish and Thickness variation were also studied and it is found that in three stages of forming for the final pass to flow form for desired size .The MDN250 (Maraging Steel) for obtaining better Mechanical properties and its geometry, thickness and mean diameter.
