Applications du calcul formel à la balistique

Abstract

AbstractThis paper gives an overview of various forms of the differential equations of exterior, interior and terminal ballistics, as well as a presentation of the problems they induce in computer algebra. Some of these problems have been investigated at ISL (French-German Institute of Saint-Louis):—through the quasi-monomial transforms (QMT) of Brenig, for the ordinary differential equations (ODE's) of exterior ballistics that have been implemented in REDUCE and led to numerical applications—asymptotic expansions of solutions of the ordinary differential equations in the “Winter thermodynamic” model of interior ballistics.In the prospects, we quote the application of the quasi monomial transform for solving ordinary differential equations, resulting of a separation of variables (by consideration of symmetry groups) of the partial differential equations of interior and terminal ballistics (with a first application concerning nuclear explosions).RésuméAprès avoir rappelé diverses formes des équations différentielles de la balistique (extérieure, intérieure et terminale), ce mémoire expose les problèmes de calcul formel qu'elles induisent. Une partie de ce vaste programme a été ébauchée: 1.avec la méthode des transformations quasi-monomiales (“TQM”) de Brenig, pour les équations différentielles ordinaires (EDO) de la balistique extérieure, implantée en REDUCE, application qui a fait l'objet de calculs numériques2.par des développements asymptotiques des solutions des équations différentielles or dinaires de la balistique intérieure “thermodynamique” dans le “cadre Winter”.Dans les perspectives, on mentionne l'emploi de cette méthode des transformations quasi-monomiales pour les équations différentielles ordinaires résultant d'une séparation des variables (par considération des groupes de symétrie) des équations aux dérivées partielles de la dynamique des gaz que l'on rencontre en balistique intérieure et terminale (avec une première réalisation sur les explosions intenses d'origine nucléaire).
