These cover a wide range of capabilities including modelling of fluids, structures, systems and costs. The Rolls-Royce Engineering System (RRES) is a system of tools, processes and ways of working, which will harness the power of Computer Aided Design (CAD), Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) codes, in conjunction with new techniques for cost engineering, manufacturing process modelling, complex system modelling and process automation to allow robust engine optimisation prior to customer commitment. Computational Fluid Dynamics (CFD) We use CFD codes to simulate the flow of fluids in and around all products, including the flow of air through all components of our diesel or gas turbine engines and their installations. Rolls-Royce actively develops its own simulation codes HYDRA and PRECISE in the UK and US and works with a number of leading universities. The HYDRA code is able to simulate the three-dimensional unsteady flows through an engine using sophisticated models of turbulence, some of which are able to capture the fine-grain chaotic structure of the turbulence. This requires the use of very large computers and HYDRA is able to utilise PC clusters of 1000’s of processors. Most of our products now make full utilisation of the 3D design space and HYDRA has been used extensively in the design of recent products such as the Trent 1000. Finite Element Analysis (FEA) FEA is the cornerstone of Mechanical Analysis and Simulation technology and is utilised from preliminary design through to in-service support and on individual components through to whole engine models. FEA is used directly for: stress, structural, life, vibration, dynamics, thermal, thermo-mechanics, aeromechanics, optimisation and robustness analysis. The specific FEA technology developed by Rolls-Royce is approved by the Certification authorities for producing Life, Integrity & Certification Statements. FEA is one of the most widely used technical capabilities in Rolls-Royce (second only to Computer Aided Design).
