Advanced Aircraft Design and Certification I Advanced Aeroelasticity Propulsion Systems Performance and Design It is needed to have a good knowledge, at grade-level, of: Aerodynamics Flight Mechanics

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.
