The Study Of Damaging Probability Model Of The AHEAD Ammunition System

This dissertation is on the basis of the firing theory of antiaircraft gun, the firingefficiency evaluation theory of antiaircraft gun, the end effect theory and the altitudeexterior ballistics, abstracts and develops the calculation method of the damagingprobability to the direct hit and the flinders hit, the AHEAD ammunition system's currentdomestic and abroad researchful theory. Firstly according to the AHEAD ammunitionsystem's structure, capability and the the movement character of the damage element,researches into and sets up the warhead and the damage field trajectory differentialequation, at the same time, analyses and supposes the equation's initial conditioncompletely and reasonedly; Then, this dissertation analyses and researches into theexperimentation method and correlative theory to evaluate target's damagablecharacteristic, and lists the datum of a representative target's. This dissertation establishsthe mathematic model of the opening cabin distance and the setting time for fuze.Moreover, by physics-math analysis, dynamic impact process between the damage fieldand the target is studied deeply. Finally, in accordance with the researchful result above,and the error analysis theory of antiaircraft gun shooting, this dissertation educes thecoordinate damaging law of the AHEAD ammunition system, the AHEAD ammunitionsystem's damaging probability mathematic model in all sorts of shooting conditions.Based the above theory model, this dissertation makes numerical simulation analysis,makes programme by using MATLAB language. We runs the programme to get thedamaging probability when the AHEAD ammunition system warhead shoot arepresentative target antiradialization missile in all kinds of shooting conditions.
