Evaluation of the Effects of a Pipeline Flow Improver on Aircraft Fuel Systems
Abstract
The US Air Force Reduced Scale Fuel Systems Simulator (FSS), the Extended Duration Thermal Stability Test (EDTST), and the Augmentor Vaporization Fouling Rig (AVFR) were used to evaluate the effect of pipeline drag reducing additives on aviation turbine fuels and aircraft fuel systems. The additive selected for this work was provided by Conoco Specialty Products and was designated CDR 102M. The additive was prepared in JP-8, JP-5 and Jet A and evaluated. In the first three runs on the FSS, a baseline JP-8 was used and additive concentrations were 50 parts per million by weight (wppm). The remaining test runs used either the JP-5 or the Jet A at 15 wppm additive. The bulk of this effort was completed using the Jet A fuel. Deposition quantification was determined through use of a Leco RC-412 Carbon Analyzer. Data obtained during this program indicate that the presence of CDR 102M increases thermal stability deposition in areas where metal wetted-wall temperatures are 450 deg F or greater. In areas where wetted-wall temperatures were 425 deg F or lower, the presence of the additive had no conclusive effect on fuel deposition.
