Modeling and simulation
Modeling and simulation: key stages in product development
As part of our product development process, Safran systematically uses 3D design technology to model all of the parts we design, from individual components to complete assemblies. To ensure that new product designs are optimized, good practices identified in previous development phases are integrated into our software.
Simulations are used to perform tests under "real" conditions, and to study complex phenomena such as turbine fan blade failure. All of the different stages of these significant events, from fragmentation of the component to engine vibrations, are modeled and analyzed. Simulation enables tailored solutions to be developed for specific situations, while limiting the number of destructive tests required.
Modeling also delivers significant reductions in development costs and lead times.
Dedicated modeling software
To ensure continuous improvement of its design methods, Safran uses a series of computational software tools, allowing complex systems to be modeled on the basis of simple geometric shapes. The tools also simulate the full spectrum of stresses to which individual parts are subjected, while applying corrections for modeling-related uncertainties.
Delivering benefits across the board
By cutting development costs and lead times, modeling and simulation act as a powerful driver of efficiency and competitiveness for Safran and our customers. Modeling and simulation technologies also enable us to propose completely new architectures, while delivering improvements in product performance (in terms of strength, endurance and fuel consumption) and reliability.
An open rotor engine demonstrator, for example, is currently being developed by Safran Aircraft Engines as part of the European Clean Sky program. This technology could potentially be used for the next generation of single-aisle aircraft. The revolutionary open rotor engine architecture uses a turbine to drive a pair of counter-rotating fans that are not enclosed within the engine nacelle – like propellers. The unshrouded fans considerably increase the engine's airflow, and cut fuel consumption by 30% compared with current designs, as well as reducing CO2 emissions.
