Students are expected to have completed
Advanced Aircraft Design and Certification II Advanced Aeroelasticity Propulsion Systems Performance and Design It is needed to have a good knowledge, at grade-level, of: Aerodynamics Flight Mechanics
Competences and skills that will be acquired and learning results.
COMPETENCES Capacity to project, build, inspect, certify and maintain any type of aircraft, including its particular subsystems. Aptitude for projecting, building, inspecting, certifying and maintaining any type of aircraft. Necessary knowledge and capacities to perform the analysis and structural design of aircrafts, including skills in advanced aircraft structural design and analysis SW tools. Capacity to design, execute and analyze Flight and Ground Tests of Aircrafts. Capacity to carry out the complete process of Aircraft Certification. Suitable knowledge of the different Aircraft Subsystems. EDUCATIONAL ACHIEVEMENTS When concluding the course the student must be capable of: Sizing the aircraft based on its mission and the adequate flying qualities criteria. Calculating the design structural loads acting on the aircraft, as well as the fatigue conditions. Based on this, to estimate the structural and operational weights. Knowing the aircraft certification requirements and specifying the means of compliance associated to them, judging their levels of acceptance. Specifying the means or tests necessary to demonstrate that the aircraft fulfills the certification requirements. Knowing and specifying and/or designing the subsystems of the aircrafts. Evaluating the operational costs of the aircraft. Evaluating the interaction between systems, flying qualities and structural loads, including failure cases. Knowing the specific design constraints of special aircraft types.
