FUTURE AIR FORCE REQUIREMENTS FOR HYDROCARBON FUELS
Abstract
The two hydrocarbon structures exhibiting the most promise as candidate high temperature fuels are the alkyl-substituted monocyclics and the alkylsubstituted condensed bicyclics. For specialized fuels, the isoparaffin structure best suits the requirements for a weight-limited fuel application whereas for an extreme high density fuel the condensed tricyclic structure exhibits the best compromise of properties. The preliminary results of a vapor fuels study indicate that the basic condensed bicyclic structure once again offers the most promise for an advanced vapor fuel. Research has indicated that a vapor fuel will extend the flight speed of advanced systems beyond mach 5. For greater speeds or for desirable additional cooling below mach 5, a type of endothermic fuel will be required. The primary contribution of the endothermic fuels program is that the feasibility of conducting this type of reaction under conditions to be encountered in advanced air-breathing systems is established and that the reaction products will perform satisfactorily in the combustor.
