Torpedo Dynamics and Homing  (English, Paperback, M. Jankiraman Ph.D)

This book is about modern torpedo technology. It is written by a torpedo expert and covers torpedo dynamics, propulsion and homing techniques. The author has spent many years designing torpedoes in all its aspects from homing to dynamics and control engineering. The topic of torpedo dynamics is written in an easy-to-understand manner with minimum mathematics. The design of the torpedo control surfaces and the implications of the torpedo angle of attack and trim are extensively discussed along with worked examples. The unique shape of the torpedo is also discussed, and it is noteworthy that, unlike missiles, there is very little scope for the torpedo shape to change. The reasons for this are discussed. The author also discusses propeller theory, because torpedo propellers are special in that they are contra-rotating and silent to radiate minimum noise. The complex issues behind such simple-looking items are discussed, again with minimum mathematics. Torpedo homing is discussed in substantial detail. 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.
