A Conceptual Design Environment for Technology Selection and Performance Optimization for Torpedoes

Abstract

The Torpedo Optimization, Analysis, and Design (TOAD) program is introduced as a parametric sizing and synthesis tool for torpedoes. Response surface methodology is introduced as a means for efficiently modeling the design space for torpedoes. Response surface equations are produced from the new thermal analysis section to model the design space for a Stored Chemical Energy Propulsion System (SCEPS) powered torpedo. Comparisons are made between SCEPS and electrically powered torpedoes, as well as between different SCEPS engine parameters. The design methods of the Aerospace Systems Design Laboratory (ASDL) are introduced for developing computationally efficient metamodels for the physics-based analysis codes used in design. Response surface methodology is shown to be an effective way to model a SCEPS powered torpedo.
