The design and fabrication of solid fuel(solid propellant) making system
A propellant grain composition for use in solid fuel rocket engines comprises a first reactant component consisting of an oxidizer, a polymeric barrier coating encapsulating the first reactant component and a second reactant component comprising a reducer fuel reactable with the oxidizer is coated in here,and a final polymeric coating is placed over the entire propellant grain to yield a single metal fuel-oxidizer propellant grain structure for use as a solid rocket fuel.It also relates to the method of preparing the propellant grain,and its fabrication. A method for preparing a solid propellant grain composition: First a first reactant component is provided which is then coated with a first encapsulating barrier material. A co-operating second reactant component, like as a metal fuel, is applied over the coated first reactant component. A second barrier material is then applied over the metal fuel reactant component to get a solid propellant grain composition. A method for preparing a shaped propellant composite includes filling a mold with a plurality of solid propellant grains, each of the grains including an oxidizer and metal fuel separately encapsulated. A curable binder component is then added to the mold. A vacuum is then applied to it for compressing the binder and solid propellant grain mixture. This mixture are cured by heat, catalyst or radiation to yield a shaped propellant composite. detailed seminar report download: The design and fabrication of solid fuel making system.pdf (Size: 356.67 KB / Downloads: 133) |
