Inverse hybrid rocket
Abstract
Abstract AN INVERSE HYBRID ROCKET WHERE A FLUID FUEL REACTS HYPERGOLICALLY IN A COMBUSTION CHAMBER WITH A NON-FLUID OXIDIZER TO PRODUCE ENERGY IN THE FORM OF HIGH TEMPERATURE GASES AS REACTION PRODUCTS, AND A MECHANISM THROUGH WHICH THE REACTION PRODUCTS ARE EJECTED TO PROVIDE POWER OR THRUST TO THE ROCKET. SEVERAL EXEMPLARY EMBODIMENTS ARE DISCLOSED, ONE OF THE EMBODIMENTS INCORPORATING A TWO-PART COAXIAL INJECTOR MECHANISM FOR CONTROLLING METERING OF THE FUEL TO THE COMBUSTION CHAMBER. THE INJECTOR MECHANISM HAS THE CAPABILITY OF EJECTING AN INNER PART OF THE TWO-PART INJECTOR WHEN A CONTROL DEVICE FOR CONTROLLING FUEL METERING ROTATES THE INNER PART OF THE INJECTOR A FULL SEMICIRCULAR DISTANCE, THEREBY DISPOSING OF THE REMAINING FUEL IN IGNITED FORM OVER A PREDETERMINED GEOGRAPHICAL AREA AT THE TERMINATION OF FLIGHT OF THE ROCKET. OTHER APPLICATIONS OF THE ROCKET INCLUDE PROPELLING A VEHICLE, DRIVING A TURBO GENERATOR, PROVIDING AIRCRAFT PROPULSIVE POWER AND PREVENTING FLAME-OUT OF AN AIR-BREATHING JET ENGINE.
