Assembly line covering the complete lubrication system.
Groups the oil pan, gasket, pickup, baffle system, cooler, adapter, fan, shroud, duct and catch can. Design Philosophies and Processes: Inherited from the Cooling, Aerodynamics subsystem design process: 1. Powertrain sets the required heat rejection from previous-year endurance data; that becomes a target mass airflow (CR26I: 0.265 kg/s water, 0.060 kg/s oil). 2. Characterise the core on the flow bench to get pressure drop against velocity, and fit Darcy-Forchheimer coefficients (water radiator viscous 1,919,749.6, inertial 52.945; oil cooler viscous 7,387,951.3, inertial 132.358). 3. Model the core in ANSYS Fluent as a porous region and the fan as a pressure jump over a fan boundary, using the manufacturer fan curve. 4. Sweep radiator angle. CR26I found 0 deg gave 0.459 kg/s with 0.78 lbf drag, +45 deg forward lean gave 0.343 kg/s with 0.31 lbf drag. Forward lean was accepted because it still beat target and cut drag and lift. 5. Design the duct and shroud around the chosen core position, then validate the assembled system with tufting and coast-down testing.
