Abstract

The density of a flightline jet fuel (JP-8) was measured with two vibrating-tube densimeters. The combined range of the data is from 270 K to 470 K with pressures to 40 MPa. The speed of sound in the fuel was measured with a propagation time method at ambient pressure from 278.15 K to 343.15 K. The estimated uncertainties of the density and the speed of sound data are each 0.1 %. The density and speed of sound results at ambient pressure were combined to obtain the adiabatic compressibility. Correlations are reported that represent the temperature and pressure dependence of the experimental data within their estimated uncertainty and can be extrapolated meaningfully beyond the data range. The data from this jet fuel are compared with those of four previously measured jet fuels to examine the compositional variability of the properties.
