ACKNOWLEDGEMENT

The contentment, the accomplishment, the magnificence, the fulfilment, the prize admiration and the creation of my project cannot be thought of without the few, who apart from their regular schedule spared their valuable time. A number of persons contribute either directly or indirectly in shaping and achieving the desired outcome.

Apart from the efforts of me, the success of any project depends largely on the encouragement and guidelines of many others. I take this opportunity to express my gratitude to the people who have been instrumental in the successful completion of this project.

I would like to extend my gratitude and my sincere thanks to my honorable, esteemed supervisor Mr. Brijesh Patel, Head, Department of Aeronautical Engineering. I would like to show my greatest appreciation to him. I cant say thanks is enough for his tremendous support and help. I feel motivated and encouraged every time I meet him. Without his encouragement and guidance this project would not have been materialized.

I owe a debt of appreciation to Mr. Brijesh Patel, Co-coordinator, M. Tech (Turbo-machinery) for providing us with an opportunity to develop this project. Through his timely advice, constructive criticism and supervision he was a real source of inspiration for me. I have had suggestions to improve this report from a number of my colleagues. I am grateful to Mr. Kalpit Kaurase, Asst. Prof., Department of Aeronautical Engineering and to colleagues who worked tirelessly in its preparation during the difficult times.

The guidance and support received from all the members of Management and especially to my college Director, Dr. A.M.Bisen to provide me resources for this project, was vital for the success of the project. I am grateful for their constant support and help.

Last but not the least I am really thankful to my family and friends for always encouraging me to achieve this goal. A special thanks to my parents, who taught me the value of hard work by their own example and who instilled me the free thinking and the joy of making researches. GOPAL SAHU LIST OF FIGURESFig. No.
