Purpose of Flight:Science
Comments:This was the fourth ACCESS test fuel exhaust emissions sampling flight with LaRC HU-25C. Fuel management procedures were modified with particular care to avoid pressurizing of the crossfeed manifold with center aux fuel except when all four engines were to operate on HEFA blend fuel. However, a rising fuel level was again detected in tank #3 when operating on HEFA blend fuel. It is now understood that the two center aux tank boost pumps that are located and submerged in tank #3 supply fuel at a greater volume than it is consumed and the pumps bypass the excess into tank #3. We now believe that all engine #2 data is valid but all engine #3 baseline JP-8 data suffers from some unknown quantity of contamination by HEFA blend fuel.
