The current ELLEA personnel took part in the following programs, preserving the related expertise and know how
Preliminary structural analysis of an aluminum Engine Block of a Diesel Engine for aeronautical application.
Creation of the FE model of a slice of the engine, including Engine Block, Bedplate, Cylinder Barrels, Cranckshaft, Bearings and connecting screws; modelling of the contact regions between components;
Non linear static analysis with application of screw pretensions and operating loads due to internal combustion;
FE analysis postprocessing and hand calculation for endurance evaluation; reporting.
Involvement in multiple projects as Tier 1 Supplier. Main activities:
FE modelling of the Engine System and Fuel System components; modal, static and dynamic (frf, psd) structural analysis for static strength and endurance evaluation under operating loads of metallic and plastic components (brackets, tanks);
CFD biphasic (air & fuel) analysis of the fuel system for the evaluation of Premature Shut-Off and Splash Back phenomena during refueling; creation of dedicated FE models and calibration based on test results.
Thermofluidodynamic biphasic simulations for De-Icing evaluation;
Refuelling System design (plastic and metallic components);
Quick Connector for the Urea Tank refuelling (plastic injection components): conceptual design, development, 3D and 2D drawings;
Urea Tank Valve for spilling prevention and venting (plastic injection components): conceptual design, development, 3D and 2D drawings;
Urea Filler Neck (plastic injection components): conceptual design, development, 3D and 2D drawings
Concept and design for the NEF engine family components (ValveTrain, Cyilinder Head, Coil Support, Harnessing)
