Concurrent Engineering
Concurrent Engineering Module SESA3002a; Aerospace Design 1 James Scanlan; School of Engineering SciencesCE Definitions: • “The application of tools, techniques, methodologies, and behavioral initiatives used to minimise product development timescales by maximising the degree of overlap of design activities.” • “A ‘buzzphrase’ with a limited shelf life” • “Optimal design.” Module SESA3002a; Aerospace Design 2 James Scanlan; School of Engineering SciencesS S Se e eq q qu u ue e en n ntttiiia a alll D D De e es s siiig g gn n n ( ( (“ “ “o o ov v ve e er r r ttth h he e e fffe e en n nc c ce e e” ” ” a a ap p pp p pr r ro o oa a ac c ch h h) ) ) C Ce en nttr ra alliis se ed d D De es siig gn n C Co on nc cu ur rr re en ntt D De es siig gn n Module SESA3002a; Aerospace Design 3 James Scanlan; School of Engineering SciencesConcurrent Engineering • Serial engineering: Good – control of two parameters Quick Cheap • Concurrent Engineering: – Attempt to control all three parameters Module SESA3002a; Aerospace Design 4 James Scanlan; School of Engineering SciencesCase Study Module SESA3002a; Aerospace Design 5 James Scanlan; School of Engineering SciencesStringer Manufacturing Early 1980’s A320 rate increase; Severe capacity problems Module SESA3002a; Aerospace Design 6 James Scanlan; School of Engineering SciencesStringer Forming Highly labour intensive, Long lead times, Quality critical. Module SESA3002a; Aerospace Design 7 James Scanlan; School of Engineering SciencesTwisting operation Concern over effect on Fatigue properties Module SESA3002a; Aerospace Design 8 James Scanlan; School of Engineering SciencesManufacturing Automation Extremely costly capital equipment; high maintenance costs, dedicated function Module SESA3002a; Aerospace Design 9 James Scanlan; School of Engineering SciencesSome historical perspective….. Module SESA3002a; Aerospace Design 10 James Scanlan; School of Engineering SciencesCE is not new; P51 DESIGNED + DEVELOPED IN 102 DAYS TECHNOLOGICALLY ADVANCED DESIGNED FOR LOW COST Module SESA3002a; Aerospace Design 11 James Scanlan; School of Engineering SciencesSupermarine Spitfire • Example of CE – Good – Cheap – Quick Module SESA3002a; Aerospace Design 12 James Scanlan; School of Engineering SciencesBf 109 7000 M/hours, much emphasis on design for Manufacture Module SESA3002a; Aerospace Design 13 James Scanlan; School of Engineering SciencesDH 98 Mosquito Arguably a good example of CE. Much emphasis on design for manufacture; Use of modular assemblies, split fuselage halves for easy equipping, minimal use of compound curves.
