b'Aerospace | Engineer Innovationthe check list. First, Airbus Helicopters has to assess the integration of the circuit in the aircraft zones with the thermal impact without exceeding maximum defined temperatures. Further, it has to be certified there is a well-designed and working hydraulic circuit that can support proper flight command functioning even in case of failures (leakage, pump failure, etc.).Based on these observations, there are two common problems that engineers must consider: the first one is development time. Indeed, getting certified is a long process. The earlier Airbus Helicopters can obtain certification, the faster it can get to market and the more competitive it can be. The second is the cost of prototypes incurred by test campaigns. So time and cost are a big part of theFigure 2: Simcenter Amesim thermal-hydraulic modelchallenge, and that is something Airbus Helicopters considers when putting together its developmentThats what Benoit Genot, hydraulic programs. and flight control engineer, and Jean-Baptiste Lopez-Velasco, thermal Predict and verify thermal-hydraulicmanagement expert, and their teams system performance decided to opt for when they were Of course, Airbus Helicopters cannotdeveloping the Airbus Helicopters even consider bypassing the prototypeH160, its six-ton, new-generation, test phase, whether it is for the systemmedium-sized rotorcraft.

For that we use Simcenter Amesim and its supercomponent capabilities to design some of our components.Benoit Genot Hydraulic and flight control engineer Airbus Helicopters43'
