Solid propellant charge for combined rocket-ram-jet engines and process for making the same
Abstract
Abstract A SOLID PROPELLENT CHARGE FOR COMBINED ROCKET-RAM-JET ENGINES CONTAINS A COMBINATION OF COMPOUNDS CAPABLE OF YIELDING UPON COMBUSTION AN EXTREMELY HIGH PERCENTAGE OF HYDROGEN AND A HIGH PERCENTAGE OF NITROGEN, BOTH CALCULATED ON THE CARBON PRESENT, SAID NITROGEN-CONTAINING COMPOUND HAVING CYANO- OR HYDRAZINE GROUPS CAPABLE OF RELEASING HIGH ENERGY, SAID COMBINATION ALSO INCLUDING AN OXIDIZER IN AN AMOUNT INSUFFECIENT FOR COMPLETE COMBUSTION. THE PROPELLENT CHARGE HAS NOT ONLY AN UNUSUALLY HIGH EFFECTIVENESS, BUT EXHIBITS AMONG OTHERS THE ADVANTAGE THAT DURING THE ROCKET PHASE NO CARBON WILL BE DEPOSITED AS SOOT, INCLUDING OTHER COMBUSTIBLE RESIDUES. THE INVENTION ALSO DISCLOSES A PROCESS FOR PRODUCING THE PROPELLANT CHARGE.
