Enhanced Scramjet Combustion

This effort is concerned with the design of CES, a rule-based expert system for forecasting vehicle corrosion and deterioration. Weight reduction and increased performances has driven the automotive industry to incorporate magnesium and aluminumcomponents in areas such as the engine compartment, frames and chassis. Unfortunately, these metals are highly active on the galvanic series and therefore have a strong tendency to corrode when in contact with other less active metals such as steel.Although the vehicles are being designed to insolate metal couples with high galvanic corrosion potential, the probability for corrosion during field operation is increased when the components or insulator is eroded or by-passed, particularly when combinedwith other forms of corrosion such as crevice and poultice corrosion.There is a general industry need for expert intelligent software that would aid the new vehicle and component designer as well as the engineer responsible for maintaining assets subject to corrosion or other deterioration. The CES product will addressfour areas of the vehicle life cycle. In the preliminary design of new vehicles it will be a design assistant providing general advice from assimilated
