Latest Patents

Chernikova holds a patent for a "Method for producing a welded-brazed combustion chamber." This invention involves a combustion chamber for a liquid-propellant rocket engine that includes an injector head jointed to a combustion chamber casing with an exhaust head on a nozzle output. The casing is constructed from a steel jacket and a bronze-steel internal fire wall, which are joined together and contain shells connected in series. The exhaust head and shells of the casing are brazed using a solder based on nickel, chromium, and manganese. Additionally, parts of the injector head and other members of the combustion chamber casing are brazed using a copper-silver solder. The shells of the fire wall are connected by electron-beam welding, directing an electron beam into axial gaps left while brazing between the shells of the jacket. Finally, the shells of the jacket are sequentially connected by automatic gas-shielded arc welding through corresponding ring spacers. Chernikova's innovative approach has led to advancements in the reliability and performance of rocket engines.
