| description | A rocket propellant includes a hydrocarbon blend having a total aromatic compounds content less than 0.5 mass percent, a specific energy of at least 18.4 KBtu/lb, and a mass density of at least 0.8150 grams per cubic centimeter. The propellant, which can be prepared by blending a refined kerosene with an isoparaffin and/or a cycloparaffin, exhibits a high volumetric heat of combustion and excellent thermal stability. This combination of properties is especially useful for fueling reusable launch vehicles employing regenerative cooling of engine components.
L'invention concerne un propergol qui comprend un mélange d'hydrocarbures ayant une teneur en composés aromatiques totale inférieure à 0,5 pour cent en masse, une énergie spécifique d'au moins 18,4 kBtu/lb, et une masse volumique d'au moins 0,8150 gramme par centimètre cube. L'agent propulseur, qui peut être préparé en mélangeant un kérosène raffiné avec une isoparaffine et/ou une cycloparaffine, présente une chaleur de combustion volumétrique élevée et une excellente stabilité thermique. Cette combinaison de propriétés est particulièrement utile pour le ravitaillement de véhicules de lancement réutilisables utilisant le refroidissement régénératif d'éléments constitutifs de moteur. |
