Aerospace engineering

Design philosophies Design philosophies for aeronautical systems: Top-down, Bottom-up Certification bodies and certificates Certification bodies: FAA, EASA, ENAC Certificates: type, airworthiness Risk analysis and failure models for aeronautical components Models for the failure of aeronautical components Fail-safe, safe-life design philosophies, infant mortality and modeling Risk analysis: Fault Tree Analysis, Markov Analysis, trace of more advanced methodologies for failure prediction (FMEA, FMECA) Exercise: risk analysis, Fault Tree Analysis, Markov Analysis Onboard systems Electrical system Generators Converters: rectifiers and alternators: CSD, IDG, VSCF Batteries Power bus and aircraft AC/DC power system architecture Bus bars and load management Ram Air Turbine and emergency bus Hydraulic system Control surface management: before the hydraulic system Hydraulic power generation Piping Actuation Valves, selector valves Back-to-back pumps and emergency systems Oil characteristics for the hydraulic system In-depth: More Electric and All-Electric aircraft and elimination of the hydraulic system: Electro-hydrostatic actuators Exercise: evaluation of pressure losses on hydraulic line for Boeing 747 Pneumatic system Bleed air from engines Control of the pneumatic system Loads: air conditioning system and anti-ice system Air Conditioning System (ECS) Optimal comfort conditions for passenger transport, risks, hypoxia, cabin altitude profile as a function of flight altitude and mission profile for commercial aircraft Structure of the air conditioning system: bootstrap cycle, heat exchangers Air delivery in cabin, air conditioning packs Exercise: sizing of restrictions for constant flow air delivery in cabin Oil hydraulic system (Engine oil) Engine lubrication and combustor turbines Structure of engine oil system Oil characteristics Heat exchange with fuel
