( Promoteur); LAGHA, Mohaned. ( Promoteur) This study focuses on the development of a flight controller for drones, utilizing both classic PIC microcontrollers and dsPICs to optimize performance. The main objective is to design and implement an embedded system capable of ensuring stable and precise control of a drone in flight. The approach includes the integration of inertial sensors (accelerometers, gyroscopes) through the I²C communication protocol, the implementation of PID control loops, and programming the microcontrollers using MikroC and MikroC Pro for dsPIC. Data acquisition and interaction with sensors were handled via I²C and UART, ensuring accurate and synchronized measurements essential for flight stabilization. Tools such as SerialPlot, Docklight, and Advanced Serial Port Terminal were used for real-time data visualization and analysis during the testing phases. The project combines modeling, simulation, and hardware/software implementation, with successive tests conducted to validate the controller’s stability and responsiveness. The results demonstrate that the developed system effectively stabilizes the drone’s main axes while addressing real-time processing constraints and precise sensor calibration. This study highlights the complementarity between PIC and dsPIC microcontrollers in meeting the demands of complex embedded systems, providing a concrete contribution to the development of compact, reliable, and scalable flight controllers applicable in aeronautics and robotics. ill., Bibliogr.

This numerical study focuses on analyzing the effect of central secondary injection in a planar divergent nozzle. The main objective is to evaluate the influence of this injection on the supersonic flow, by examining changes in jet structure, pressure distribution, and the possible alterations in internal shock waves 019/2025 option: Propulsion 2025-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/40490 Étude théorique, numérique et expérimentale d’une éolienne HAWT : de la modélisation BEM à la simulation CFD TAMADARTAZA, Amayes;; LOUAZANI, Mustapha Younes;; Dr. ALLOUCHE, Rachid (promoteur);; Dr. RENANE, Rachid (promoteur); Ce mémoire traite de la conception et de l’optimisation aérodynamique d’une éolienne à axe horizontal adaptée aux conditions venteuses en Algérie. Une approche multiétape a été adoptée, comprenant une modélisation théorique par la méthode des éléments de pales (BEM), une optimisation sous QBlade, et une validation numérique par simulation CFD sous ANSYS Fluent. L’analyse a permis de sélectionner un profil aérodynamique performant )S803(, d’optimiser la géométrie des pales )corde, vrillage( et d’évaluer les performances sous différentes conditions de vent et d’angle d’incidence. Les résultats CFD ont été comparés aux simulations BEM, et validés partiellement par des données expérimentales. Le travail met en évidence l’importance de l’analyse paramétrique et de la qualité du maillage sur la précision des prédictions numériques. Des recommandations de conception sont proposées pour améliorer les performances globales. 012/2025 option: stucture 2025-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/40474 Analyse modale et étude des fréquences propres des réservoirs de carburant pour moteur-fusée Mellouk, Islem Hafedh;; Abada, Omar(promoteur);; Abdallah Elhirtsi, AHMED( Promoteur); In this study, two types of rocket fuel tanks were analyzed: a cylindrical tank, a spherical tank and a wing profile containing an integrated tank. Modal analysis was performed using ANSYS and COMSOL to evaluate the impact of various parameters (shape, material, thickness, etc.) on the natural frequencies. The results showed that some factors have a significant influence on the frequencies, while others have a limited effect. A good agreement was observed between the results from both software tools. 006/2025 option: structure 2025-01-01T00:00:00Z
