0 GENERAL INTRODUCTION Historically, the Aeronautics and Aerospace specialization is the oldest one offered to students by EPF, in fact, Aeronautical studies were introduced in 1933 and are still part of the program. The educational objectives of the Aeronautics and Aerospace specialization are to enable our engineering students to reach their maximum potential in order to challenge problems encountered in the design of space vehicles, especially focusing on environment and sustainable development issues. This specialization gives the requisite and necessary knowledge in aerodynamics, space mechanics, materials, structural analysis, propulsion, flight mechanics applied to design of different types of vehicle: aircraft, helicopter, missile, launcher, drone and satellite. These courses are represented by design offices and 2 major projects: >> Project of design and performances analysis of military aircraft >> Project of satellite launcher design By the end of this specialization, the graduates have been able to take full advantage of their engineering studies, to develop and acquire operational and technical skills, using the techniques, methods and constraints characteristic of a professional course.
