1D system simulation is now well deployed over the engine development cycle, especially for engine and component design. 1D codes have been used for years in two very distinct areas: for the simulation of gas dynamics in the air path in order to evaluate engine performance, and as a support for the design of the actuators allowing the connection of hydraulic and pneumatic, mechanical and electrical components. During the engine integration stage, the set-up of the actuator on the engine and the calibration of the associated control strategies are generally achieved on the test bench, which leads to a time and cost consuming process. The use of a dedicated model for the analysis and optimization of the integration of the engine actuation system represents a real added value.
