Competences and skills that will be acquired and learning results.
At the end of the course the student should be able to: -Identify manufacturing process capabilities. -Select properly the technology or group of technologies to product a piece, component or mechanism attending to its application. -Select the type of material to manufacture a piece, component or mechanism considering different aspects as service life, machinability and maintenance. -Recognize and predict a potential failure in aerospace structures and propulsion systems with analytical and numerical techniques.
Description of contents: programme
REQUIREMENTS TO MANUFACTURING PROCESSES: PROCESS CETIFICATION, DESIGN Engineering requirements: data for manufacturing Quality requirements. Cost requirements Environmental requirements Lead time Plant lay-up Stability of the process: development vs production. Certification of manufacturing processes. MANUFACTURING PROCESS CAPABILITIES. Why we need to fix these capabilities How to define process capabilities Repeatability of the process Statistical analysis of manufacturing capabilities Tolerances Defects (composite materials) CONCURRENT ENGINEERING: MATERIALS, DESIGN AND PRODUCTION INTEGRATION Why concurrent engineering Product view from different company areas: local target vs global target Thinking out of the box. Mutual challenge and collaboration Concurrent engineering vs technologies Advanced Composite Materials MANUFACTURING PROCESSES FOR ADVANCED COMPOSITE MATERIALS: AUTOCLAVE PROCESS, RTM, FILAMENT WINDING. Processes Tooling (thermal effects) Vacuum bag Sandwich Defects Drilling Bonded Final trimming Joning FEM (Machining process simulation) MANUFACTURING PROCESS FOR POLYMERIC MATERIALS MANUFACTURING PROCESSES FOR SUPERALLOYS. FEM (Machining process simulation) INFLUENCE OF MACHINING AND ASSEMBLY PROCESSES ON SERVICE INSPECTION. Maintenance and inspection activities for in Service aircrafts Accessibility Design/production for maintenance In service damage. Allowable damage definition.
