LIQUID-PROPELLANT ROCKET ENGINE GAS GENERATOR Russian patent published in 2002 - IPC

FIELD: liquid-propellant rocket engines. SUBSTANCE: gas generator has cooled combustion chamber, injector head, front, center and injector faces, oxidizer and fuel injectors and excessive component distributor mounted along axis of gas generator and made in form of hollow cylinder closed by longitudinal face. Distributor is provided with mixing members for delivery of excessive component to mixing zone; mixing members are made in form of hollow perforated cylinders closed by perforated tent-shaped heads; they are arranged in staggered order over lateral surface of distributor at reducing height in way of gas flow. Radial profiled plates located on distributor between injector face mixing members are provided with passages for delivery of component from cavity of distributor to cavity of gas generator chamber; they extend over entire height of plate. Distributor face is made in form of truncated cone with its vertex directed towards injector face. Holes are provided at area where cylinder changes to face and in vertex of cone. EFFECT: enhanced reliability of gas generator; possibility of obtaining smooth temperature field at outlet; enhanced operational stability. 3 dwg
