7. 20 th June 2013 Rolls-Royce proprietary information Success Speed is needed Speed gives you options

8. 20 th June 2013 Rolls-Royce proprietary information Design is Complex The design process feels a bit like this, but

9. 20 th June 2013 Rolls-Royce proprietary information Actually it looks like this One subsystem, x8 for whole engine Many inter-dependencies between subsystems

10. 20 th June 2013 Rolls-Royce proprietary information Challenges It is now not possible to design a competitive gas turbine without the extensive use of Simulation To keep competitive requires us to develop our capability at an increasing rate. Hence we Need Speed in automation and integration of simulation tools, methods & the embedding of knowledge. ie the creation of ‘Design Systems’ 10

11. 20 th June 2013 Rolls-Royce proprietary information 11 What’s the motivation for Simulation? Design better products – higher performing, lighter, cheaper, more reliable, less polluting…… Design more effectively and efficiently – speed through automation, better accuracy…… Replace testing by Simulation to cut development costs. Make more effectively and efficiently - reduce scrap and rework in production. Over to Craig 

13. “Virtual Engineering is aimed at allowing the synthesis, analysis, evaluation and optimal development of a product in a computer environment that mimics the understanding and behaviour of the solution to the realization of that solution in reality”. Virtual Engineering Consider all the other required models - FEM, Physics, cost, process – are they coupled Knowledge Based Engineering Lab

14. Legislative standards Multiple topologies Its never really been about the ‘Geometry is the Master Model’ & associated documentation - Consider a Simple Shaft Cost Rules Standard bar size Material cost (type, volume, economic batch size) Direct labour costs Overhead costs per machine (machine/hr rate) Lowest cost route Extras pricing band Manufacturing Rules Machine capacities Machine capacity (tolerance) Machine set-up times NC tool path information Grinding allowances Tooling availability Material availability Fastest throughput, route Material type Engineering Rules Bearing size to suit shaft diameter Bearing life to suit load and life requirements Calculation of bearing life Tapped end hole to suit shaft diameter Tap length to engineering standards Surface finish to suit auxiliary components e.g. Oil seal Calculation of max permissible load (load type: radial, axial, combination) Weld calculations (possible/strength) for hybrid shafts Shaft diameter for brake size Fan or non-fan vented Keyway size to suit diameter Tolerance to suit required standard and final assembly Material properties Thread and keyway standards Motor output and phase Geometric Rules Extension overall length Shaft overall length Extension diameter Keyway length Keyway width Bearing diameter Rotor groove positions Fan area diameter Chamfer dimensions Fillet dimensions Undercut dimensions Number of extension segments Multiple Model Requirements Engineering Processes Knowledge Based Engineering Lab

18. Chrysler uses a system known as Knowledge Based Engineering, a combination of software tools and engineering data. The program can run simulations to test parts and then adjust those parts instantly. But it goes further than most computer- assisted design programs; it can also adjust every part a new piece touches -- looking at the entire vehicle. Chrysler's new Dodge Challenger was completed in 21 months, trimming nearly a year off the time it takes to complete most vehicles. "What literally took months can now be done in weeks," said Pamela Larson, manager of rear-wheel drive virtual development. "Instead of spending our time developing many things, we're refining it."
