Abstract:
A method for directing a vehicle, said method comprising the steps of:propelling said vehicle by reaction forces attributable to the flow of high-temperature propulsion fluid through a nozzle; heating the fuel grain of a secondary exhaust fluid generator by one of (a) heat from said high-temperature propulsion fluid and (b) a trickle of oxidizer applied to said fuel grain, to thereby maintain said fuel grain of said secondary exhaust fluid generator ready for combustion with a flow, greater than said trickle, of said oxidizer, for thereby generating significant amounts of said secondary exhaust fluid when a flow of said oxidizer, greater than said trickle, is applied to said grain; and injecting said secondary exhaust fluid into said nozzle in an asymmetric fashion, for altering the thrust vector.
