Materials Selection in Electromagnetic Launcher Design

Optimization of Three - stage Electromagnetic Coil Launcher

For the design of three-stage electromagnetic coilgun, many parameters and their relations must be considered at the same time. However, there is no complete mathematical model to describe the relationship between these parameters and energy conversion efficiency of the coil launcher system. In this paper, using orthogonal test approach we consider the influence of 11 parameters to improve the ...

Materials selection in mechanical design

A novel materials-selection procedure has been developed and implemented in software. The procedure makes use of Materials Selection Charts: a new way of displaying material property data; and performance indices: combinations of material properties which govern performance. Optimisation methods are employed for simultaneous selection of both material and shape. INTRODUCTION The performance of ...

Operating Modes for Compulsator Based Electromagnetic Launcher Systems

Materials Selection, Modeling and Mechanical Design

These lecture notes address materials and structures issues associated with the MIT Microfabricated gas turbine engine. An overview of the project and the performance goals is provided. These are translated into requirements for the materials and structural design. Particular emphasis is provided on the approaches taken to designing with brittle materials at low temperatures and designing with ...

Design and Testing of a Rapid Fire, Lightweight, Ultra Stiff Railgun for a Cannon Caliber Electromagnetic Launcher System

The goal of the Cannon Caliber Program is to drive 185 g integrated launch packages to 1,850 d s . Three, fiveround salvos with a firing rate of 5 Hz are intended to defeat specified targets at a range of up to 3 km. After an extensive alternative study, the design team consisting of United Defence FMC/BMY, the Center for Electromechanics at The University of Texas at Austin (CEM-UT) and Kaman ...
