Experimental studies of Pre-X vehicle heat transfer in PGU-7 test facility
A number of on-ground tests on aerothermodynamics (ATD) of the Pre-X flight demonstrator at cold supersonic flow regime was made in 2006 in Central Research Institute of Machine Building (TsNIImash, Russia) together with Centre National d'Etudes Spatiale (CNES, France). Objectives of these ATD tests were to obtain experimental data on heat transfer to the Pre-X scaled (1:15) model surface under on-ground experimental conditions to contribute them into the ATD database. The ATD tests included experimental characterization of heat transfer to the model surface using infrared (IR) and calorimetric measurements and were carried out in a piston gasdynamic facility (PGU-7) of TsNIImash. Heat transfer measurements were conducted for a M∞ = 10 PGU-7 flow regime at three characteristic Reynolds numbers, three different angles of attack, two sideslip angles, and four flap deflection angles.
