摘要

In the frame of the ESA flight experiment EXPERT thernmajor aerothermodynamic phenomena around tworncontrol surfaces and their cavities have beenrninvestigated with experimental and numerical methods.rnThe flow upstream of the flap is characterized byrnPayload 7 of CIRA using heat flux sensors. Therninstrumentation of the C/SiC flap and cavity will allowrnmeasuring the surface temperature, pressure and thernheat flux rate using high temperature sensors (Payload 6rnof DLR). The rear surface temperature distribution ofrnone of the flaps will be measured with an infrared (IR)rncamera (Payload 8 of RUAG). This data will be used torncompute the front surface heat flux distribution using anrninverse method analysis. Characterization tests in thernSCIROCCO facility will allow calibrating the completernmeasurement system and data reduction software, sincernin contrast to the flight the front surface temperature ofrnthe flap will be measured with an additional IR camerarnof the facility.
