For that we use Fahrenheit in outside air temperature. Simcenter Amesim and its supercomponent capabilities to design Our first objective was to design asome of our components.rough architecture of a hydraulic circuit, says Genot. Each hydraulicSecondly, it is crucial to understand the power supply unit is composed of athermal influence of the hydraulic tank, sensors (temperature/pressure/ system on some of the helicopter parts. fluid level), pumps and an emergencyIndeed, once integrated into the pump in case of a failure of one of thehelicopters, the hydraulic circuit mainlyOne of the questions that Simcenter Amesim helps us clarify is whether it is required to cool the fluidin that case we need to use a heat exchanger.Jean-Baptiste Lopez-Velasco Thermal management expert Airbus Helicopters44'
