Hierarchichal Current Control Design For Electromagnetic Aircraft Launching System

This paper describes an approach to hierarchichal modular control for an electromagnetic aircraft launching system for the aircraft carrier of the future. The purposes are to analyze the possibility of improving the control performance using efficient evaluation of switching conditions, and to explore the different options for the basic control design and the way in which these designs will be ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Absorbing boundary conditions for electromagnetic wave propagation

In this paper, the theoretical perfectly absorbing boundary condition on the boundary of a half{space domain is developed for the Maxwell system by considering the system in whole instead of considering each component of the electromagnetic elds individually. This boundary condition allows any wave motion generated within the domain to pass through the boundary of the domain without generating ...

Design, Fabrication, and Testing of Composite Energy-Absorbing Keel Beams for General Aviation Type Aircraft

A lightweight energy-absorbing keel-beam concept was developed and retrofitted in a general aviation type aircraft to improve crashworthiness performance. The energy-absorbing beam consisted of a foam-filled cellular structure with glass fiber and hybrid glass/kevlar cell walls. Design, analysis, fabrication and testing of the keel beams prior to installation and subsequent fullscale crash test...
