Abstract
A high density liquid hydrocarbon fuel composition singularly suited for propelling turbojet limited volume missile systems designed for shipborne deployment. The contemplated fuels are basically composed of the saturated analogues of dimers of methyl cyclopentadiene and of dicyclopentadiene and optionally include the saturated analogues of the co-trimers of said dienes or the trimers of cyclopentadiene. The various dimers and trimers are combined in a relative relationship to provide optimal performing fuels for the indicated purpose.
Claims4
A composite high density fuel having a net heat of combustion of at least 140,000 BTU/gal., a flash point between 140.degree. and 150.degree. F. and a viscosity not in excess of about 30 cps at 0.degree. F.;
- said fuel consisting essentially of (a) 35-90 wt. % of an isomeric mixture of tetrahydromethylcyclopentadiene dimers conforming to the physical property specifications for RJ-4;
- (b) 10-40 wt. % exo-tetrahydrodicyclopentadiene;
- and (c) 0-30 wt. % of the hydrogenated derivatives of a co-trimer of cyclopentadiene and methyl cyclopentadiene or a trimer of cyclopentadiene.
