This book is about modern torpedo technology and naval mine design. It is written by an expert in underwater weapon systems. The author has spent many years designing torpedoes in all their aspects from homing to dynamics and control engineering, as well as torpedo proximity fuzes. He has also designed all types of naval mines. The author initially discusses the nature of underwater explosions and the detailed designing of torpedo electromagnetic (EM) proximity fuzes based on it. The topic of EM proximity fuzes, considered a complex subject, is treated in an easy-to-understand manner. The topic is well explained with examples. Torpedo homing is then discussed in substantial detail as well as wake homing. The author discusses basic sonar theory for the uninitiated. He then discusses the evolution of torpedo homing and concludes with a cursory examination of the homing head of a contemporary torpedo.
The author then discusses the origin of naval mines and the various types of mines in existence. This topic is well explained with mathematical examples from the basic shell design to more complex naval mines. Special emphasis is given to ground mines and anchor mines. The limitations and advantages of each are discussed as well as problems encountered in minelaying. Specialized naval mines like the submarine-launched mobile mines (SLMM) are also examined as well as gliding mines. The complex issues behind the design of elaborate naval mines are discussed, again with minimum mathematics.
This book is designed to serve as a basic primer in such topics and it is hoped, will be appreciated by all involved in this field.
M. Jankiraman Ph.D
Dr. M. Jankiraman is an alumnus of the National Defence Academy, Khadakwasla, and passed out in 1967. He thereafter graduated from the Naval Electrical School, Jamnagar, India in 1971 receiving his B. Tech. Degree in Electronics and Telecommunications. Subsequently, he served as an Electrical Officer in the Indian Navy for many years. In 1982 he was seconded for research work in military electronics. He took part in several military research projects in India and won several awards for technology development in India. His research has spanned several disciplines, emphasizing signal processing, in the development of naval mines, torpedoes, sonars, radars, and communication systems. He was awarded the Defence Research and Development Organization, DRDO, award of "Scientist of the Year 1985" for his work in developing naval mines. He retired from the Indian Navy in 1995 with the rank of Commodore and joined the International Research Centre for Telecommunication-transmission and Radar (IRCTR) at the Delft University of Technology, Netherlands in 1997. He completed his degree of Master of Technological design (MTD) in radars in 1999, graduating cum laude, and went on to complete his Ph.D degree from the University of Aalborg, Denmark in wireless communications in September 2000. He is a Senior Member of IEEE (USA) and a Fellow of IE (India).
