Abstract:

The use of the low temperature LT flowability-improving additive developed in the JP-8100 LT program was studied for use in Jet A fuels. The results indicate that the LT additive does improve the flowability of near specification maximum freeze point FP Jet A fuels near -40 deg C when employed at a concentration of 2,000 mgL to a flowability equivalent to near specification maximum FP JP-8 fuels near -47 deg C. Viscosity measurements demonstrated that the LT additive increases the fuel viscosity at temperatures above incipient fuel crystallization, where the fuel remains a liquid. It is recommended that further work be performed before the LT additive is fielded for use in Jet A fuel. In particular, the effect of the increased fuel viscosity at liquid fuel temperatures needs to be evaluated in the particular aircraftengine platform being employed.
