Fuel Tank Deposits in an SST Environment

Fuel temperatures resulting from the SST environment may cause Jet A kerosene to form solids which can adhere to fuel tank surfaces in localized areas. The environmental conditions influencing the formation and accumulation of deposits within the SST fuel tanks are examined and the potential problems with these deposits assessed. Methods of reducing the accumulation of deposits are investigated. The results of these investigations with the proposed SST fuel tank structure have led to the conclusion that the accumulation of deposits with Jet A kerosene fuel would not be excessive.
