Abstract : The objective of this project was to provide estimates of the availability, cost and quality of naphthenic hydrocarbon fuels for advanced hypersonic vehicle propulsion as a function of time. To accomplish this objective a proposed specification of the fuel was established. Potential sources of feedstocks were surveyed with particular attention to petroleum based refinery streams. Three promising feedstocks were identified in addition to purchased petroleum derived naphthalene, which served as the bases of comparison. Processing routes to convert the identified feeds to specification fuel were identified. These are based on existing refining technology and require no process innovation or research for successful fuel production. The samples of the proposed fuel substantially met the desired properties of the advanced fuel. In addition rate constants were derived for the hydrogenation of naphthalene and the cis--trans-isomerization of decalin. Other rate constants relevant to the production of advanced fuel from refinery feedstocks were also measured. The requirements for the design fo the aircraft system to use these fuels were estimated. The availability and cost of advanced fuels form the identified refinery streams were estimated and a possible scenario for supplying this fuel through the year 2000 was developed. The advanced fuel in question is intended for application in hypersonic aircraft of the future, particularly those intended for high mach flight with extensive fuel cooling of the airframe and engine.
