SWINGING ASSEMBLY OF LIQUID-PROPELLANT ROCKET ENGINE Russian patent published in 2000 - IPC

FIELD: liquid-propellant rocket engines. SUBSTANCE: swinging assembly has chamber and pipeline carrying engine products of gas generation and running from turbine to chamber. The latter is mounted relative to pipeline for spatial displacement about point in vicinity of or on chamber axis at preset solid angle. Movable spherical sealing joint incorporating head and shell is provided between chamber and pipeline. Either head or shell has spherical sealing surface and other one has seat accommodating annular sealing member held tight against spherical sealing surface, for example, by means of spring; this member is made of sealing material such as polyfluoroethylene possessing low coefficient of friction on mentioned spherical sealing surface; head and shell are provided with through channels directly communicating on inlet side with gas-generation product delivery pipeline and on outlet side, with engine chamber. EFFECT: facilitated manufacture, reduced cost and size of combustion-chamber swinging assembly. 9 cl, 6 dwg
