METHOD OF MAKING CHAMBER OF LIQUID-PROPELLANT LOW-THRUST ROCKET ENGINE Russian patent published in 1995 - IPC

Abstract SU 1762603 A1

FIELD: rocket engineering. SUBSTANCE: chamber is intended for operation at high degree of completeness of fuel combustion (ϕo=0.95-0.97). The chamber is integrated from case 1 heat-proof nozzle insertion 2 disposed along the mounting surfaces; then the insertion is fixed inside the case. Insulating heat-proof material 3 is preliminary applied to external concave surface of insertion 4. Fixation is carried out by reduction (running-in) of external surface of the case at the area of insertion. Case is made of stainless steel. Nozzle insertion is made of heat-resistant and high-temperature alloy. It may also be made of ceramics or graphite. EFFECT: improved efficiency. 1 dwg
