Modeling of 3-stage Electromagnetic Induction Launcher

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 ...

Operating Modes for Compulsator Based Electromagnetic Launcher Systems

Model Based Desgin Environment for Launcher Upper Stage GNC Development

The cost associated with developing flight control forms a significant part of the overall development cost. The increased demand for greater functionality and for extending the domain of applicability of future launchers leads to higher complexity of the GNC algorithms. Furthermore, there is also a need for a responsive design methodology, which can quickly adapt to changes in the requirements...

Electromagnetic Induction Studies

This report constitutes an attempt to review the major developments and identify important trends in the broad field of geophysical electromagnetic nduction and related phenomena over the past four years. Following in the spirit of previous reports of this type [e.g., Filloux, 1979; Hermance, 1983b], the work of US researchers will be emphasized, although we will cover foreign research when app...

Electromagnetic Induction ( Paper Ii )

Typical components of a metal detector include a transmitter and receiver coil. As depicted in Figure B.1, electric currents that flow in the transmitter coil radiate a primary magnetic field that penetrates the surrounding medium and any nearby metallic object. A timechanging primary magnetic field will induce so-called eddy currents in the buried object, and these currents in turn radiate a s...
