Lire la suite >Surge and rotating stall are unstable flow phenomena which can occur in aeronautical compressors operating at low flow rate. They represent serious concerns for flight safety as their arising can lead to some dramatic accidents. Consequently, the engine manufacturers and users introduce safety margin to avoid that surge and rotating stall set-in the compression stages of the engines they consequently deprive the machine from its higher pressure ratios and higher efficiencies. An improvement of the so-called ‘surge margin’ can directly allow to have a beneficial impact on the engine weight by reducing the number of the compressor stages and thus on its Specific Fuel Consumption.The present European financed project focus on the extension of the stable operating range of axial compressors by controlling the flow at compressor blade tip thanks to fluidic jets blowing at the machine casing. The final goals consist of reducing the surge margin by postponing the stall onset. More specifically, the objective of the ACONIT project is to design, manufacture, and test actuators for flow control to integrate in an aircraft engine. The actuators must, therefore, fulfill aeronautics requirement in order to increase the Technology Readiness Level (TRL) in this domain.Lire moins >
