Abstract: The purpose of this work is to implement the lean manufacturing tools in Lamina Suspension Products Ltd. - an Indian manufacturing sector and develop a plan for reducing lead-times and increasing the output. Theincrease in lead-times due to undefined batch size and poor product flow is causing the manufacturer a loss in market share to its competitors and thus the challenge is to provide qualitative products with reduced lead time. Value stream mapping (VSM) – a lean tool is used to determine areas of potential improvement on the plant floor. The paper concentrates on the production line of main leaf spring. A current state map is developed and analyzed, to pin point areas that have potential for improvement. After analyzing the current map and discussing with the experts, a future state map is created to suggest ways to reduce lead-times and increase productivity/output. The map will include lean manufacturing methods to enhance the productivity and reduce the lead time.

Abstract: In most of the practical gas turbines, the turbine blades of HP stage are usually too small to employ the turbine blade cooling techniques effectively. The growing need for effective blade cooling techniques is a direct consequence of the continuous quest for greater fuel economy. It is very well known that the thermal efficiency and power output of gas turbines increase with increasing turbine entry temperature (TET). The current TET level in advanced gas turbines is far above the melting point of the blade material. An attempt has been made in this paper to computationally analyze the thermo-structural analysis of HP stage turbine blade for effective cooling using innovative cooling passages within the blade. A helicoidal shaped duct has been analyzed corresponding to different cross section, diameters and pitch length. It is found from the analysis that helicoidal cooling duct of circular cross section of pitch length 6 mm radius 2 mm having turbulators (e/D = 0.08 and 0.75 mm rib t
