Aerodynamic Environment and Flight Measurement Techniques of EXPERT

[Abstract] This paper reports on the aerothermodynamic (ATD) environment of the EXPERT configuration associated with the planned first flight (5km/sec trajectory). A status report is given on the embarked flight measurement technique developments and qualification with emphasis on the thermal protection system (TPS) integration issues. Special attention is given to the design of the flight measurement sensors themselves, their integration into the TPS as well as to the measurement of the free stream parameters during re-entry using an Air Data System (ADS). The paper will address the numerical design work to optimise the location of sensors in order to enhance the phenomena of interest.
