Available in PDF, EPUB and Kindle. Book excerpt: This book, a translation of the French title Technologie des Propergols Solides, offers otherwise unavailable information on the subject of solid propellants and their use in rocket propulsion. The fundamentals of rocket propulsion are developed in chapter one and detailed descriptions of concepts are covered in the following chapters. Specific design methods and the theoretical physics underlying them are presented, and finally the industrial production of the propellant itself is explained. The material used in the book has been collected from different countries, as the development of this field has occurred separately due to the classified nature of the subject. Thus the reader not only has an overall picture of solid rocket propulsion technology but a comprehensive view of its different developmental permutations worldwide.

Available in PDF, EPUB and Kindle. Book excerpt: L’ouvrage présente avec clarté et précision les différents aspects de la propulsion anaérobie. Il s'adresse aux étudiants en formation initiale d'ingénieurs et de master ou complémentaire dans un cycle doctoral. L’exposé reprend d’abord les concepts de base en mettant l'accent sur les points clefs en relation avec la propulsion aéronautique. Les concepts développés doivent permettre au futur ingénieur de comprendre les aspects qui prévalent à la conception et au calcul des performances des fusées. Il s’agit de l’architecture des fusées et des fluides (ergols liquides ou propergols solides). Ces concepts sont fondés sur la thermodynamique des systèmes réactifs, dont les lois générales sont rappelées, ainsi que les lois de la dynamique des fluides relatives aux écoulements dans les tuyères. Les auteurs font de nombreuses références à des systèmes propulsifs actuellement mis en œuvre dans le monde et plus spécifiquement aux USA et en Europe. Les outils numériques et les concepts présentés permettront au lecteur de réaliser des avant-projets réalistes, préalables aux développements technologiques ultérieurs.

Available in PDF, EPUB and Kindle. Book excerpt: This work concerns the conception, the realization and the characterization of solid propellant microthruster array integrated on silicon. These MEMS devices are devoted the stabilization of small drone and also be used as propulsion module for Micro/Nano-Satellites. This study was made within a national project financed by the French Military Agency (Direction Générale pour l'Armement 'DGA') in partnership between the LAAS-CNRS and the PROTAC of THALES group. The concept is based on the high rate combustion of solid propellant or explosive stored in a micromachined chamber. The ignition process is insured by heating effect of a polysilicon resistor micromachined on thin membrane. The generated gases are accelerated throw the micro-nozzle and supply the thrust force. In a first step, we estimated the propulsion forces needed for stabilize the small drone in flight. he solid propellant micropropulsion mode is chosen because it is not complicated technology, need low power supply and generate a large rang of trust. For a specified energetic material, the generated force is adjustable from few 100μN to N simply by modifying the nozzle throat dimension. In this manuscript, we present first of all, the DGA specifications used for conception, the technology of manufacturing and assembly developed at LAAS. Finally, the thrust characterization results are given.

Book excerpt: LA PHASE CONDENSEE PRESENTE DANS LES PRODUITS DE COMBUSTION A UNE INFLUENCE SUR LA STABILITE DE FONCTIONNEMENT D'UN MOTEUR A PROPERGOL SOLIDE. COMME DANS UN PROPULSEUR SEGMENTE, LES INSTABILITES RESULTENT DAVANTAGE D'UN COUPLAGE DES CHAMPS AERODYNAMIQUE ET ACOUSTIQUE QUE DE LA COMBUSTION PROPREMENT DITE, SEULE UNE SIMULATION NUMERIQUE DE L'ECOULEMENT A L'INTERIEUR DE LA CHAMBRE SEMBLE PERMETTRE DE DECRIRE LE COMPORTEMENT DU MOTEUR. L'APPROCHE RETENUE EST BASEE SUR UNE DESCRIPTION EULERIENNE DE CHACUNE DES PHASES AVEC TRAITEMENT DES INTERACTIONS MUTUELLES. CELLES-CI COMPRENNENT LES FORCES DE TRAINEE, DE PORTANCE ET DE VOLUME AINSI QUE LE TRANSFERT DE CHALEUR PAR CONVECTION. L'ARCHITECTURE DU CODE REPOSE SUR UN CONCEPT MODULAIRE. LE SOLVEUR DE LA PHASE DISPERSEE AINSI QUE LE MODULE DE COUPLAGE ONT ETE CONSTRUITS AUTOUR D'UN CODE MONOPHASIQUE DE L'ONERA.

LES COMPARAISONS SIMULATIONS-EXPERIENCES ONT SOULIGNE LA PERTINENCE DE L'APPROCHE NUMERIQUE RETENUE. LA FREQUENCE DU DETACHEMENT TOURBILLONNAIRE EST BIEN RETROUVEE. LES NIVEAUX DES OSCILLATIONS RESTENT EN REVANCHE DEPENDANTS DE PARAMETRES NUMERIQUES TELS QUE LE MAILLAGE OU LE SCHEMA DE VISCOSITE ARTIFICIELLE
