Density, speed of sound, and viscosity have been measured for samples of RP-1 and RP-2 that were stressed for 0.5 min at 475 °C and 510 °C at a pressure of 17 MPa. Density and speed of sound were measured from 5 °C to 50 °C for the samples stressed at 475 °C and from 5 °C to 35 °C for the samples stressed at 510 °C. Viscosity was measured from -10 °C to 50 °C and to 35 °C for the samples stressed at 475 °C and 510 °C, respectively. All measurements were made at ambient atmospheric pressure (~ 83 kPa). Additionally, the density and sound speed data were used to derive adiabatic compressibilities and those results have also been included. Current results for the thermally stressed samples were compared to previously reported measurement results for unstressed RP-1 and RP-2. For all reported properties, increased thermal stressing resulted in increased fuel decomposition and increased deviations from unstressed values.
