This book explains certain transducer design developments resulting from the Sonar Transducer Reliability Improvement Program, such as the Simplified Guidance Model for k33-mode transducer elements. The models usefulness in understanding and explaining certain transducer design techniques for a 33-mode projector element and array is discussed. The model is augmented and applied such that it may be used 1 as an educational tool to help inexperienced transducer design engineers acquire some subject knowledge, skills and insight and 2 to illustrate some pertinent design and analysis aids. Section 2 establishes a basis for developing these design and analysis tools by providing one illustration of a systematic General Design Approach. In Section 3, one aspect of this approach is further clarified with a specific example. Section 4 considers the design options available to the engineer when all of the transducer design parameters except the ceramic stack assembly and the fiberglass tuning ring are fixed. In Section 5, the model is augmented to include the entire transducer and applied to derive and illustrate certain design aids. Appendix A contains many derivations used in the main text. Appendix e presents computer program predictions for selected examples in Section 5.
