Ceramic materials due to their high compressive strength and hardness have been one of prime candidates in armor design in particular when high level threads (impact velocity above 600m/s) are involved. The aim of this work is to investigate ballistic impact resistance potential for a target plate with novel ceramic inserts as against ceramic tiles. Two size 98% alumina (AL2O3) base ceramic i...

n the Air Defense Systems Department, systems engineering is a way of thinking. More than a “process,” the systems perspective drives our approach to solving emerging air and missile defense problems as the threat becomes more advanced and the tactical environment more complex. This perspective and the requisite tools have evolved with the increasing complexity of those systems. In this article...

The problem of optimally allocating partially effective, defensive weapons against randomly arriving enemy aircraft so that a bomber maximizes its probability of reaching its designated target is considered in the usual continuous-time context, and in a discretetime context. The problem becomes that of determining the optimal number of missiles K(n,t) to use against an enemy aircraft encountere...

an internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. inthis model a 1-d unsteady euler equation with source terms is considered. the flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. the governing equations in the combustion chamber are solved numerically by using the stege...

The paper describes a methodology for characterizing the signatures of targets for Imaging Infrared (IIR) missiles and generating dynamic missile engagement scenarios using MathWorks tools (primarily MATLAB and Simulink). The over-all objective of this work was to develop high fidelity physics-based simulations of the attack of IIR missiles on targets that are using various types of countermeas...
