DEVICE FOR TAKING THRUST AND FLOW OF TWO FUEL COMPONENTS Russian patent published in 2015 - IPC F02K9/44 F02K9/66 

FIELD: engines and pumps.

SUBSTANCE: invention relates to rocket engineering, namely to devices taking thrust of a liquid-propellant engine (LPE) and allowing to provide a flow of fuel components from rocket tanks in the main engine line and engine rocking. In the device taking thrust and flow of two fuel components, which includes a two-degree suspension and a bellows assembly for flow of two fuel components; with that, as the above suspension there used is a cardan suspension having a frame of a cardan mechanism, two pairs of axes with bearings arranged in the frame in two mutually perpendicular planes, and two pairs of forks connected to the axes; with that, one pair of forks is rigidly attached to the engine frame, and the other one is attached to the head of the engine combustion chamber; with that, the above bellow assembly is arranged inside the frame of the cardan mechanism and made in the form of two bellows - an internal one installed on the engine axis and the axis of the cardan suspension and an external bellow concentrically arranged relative to the internal one, which form an annular channel between each other; the cavity of the internal bellow is connected on one side to the cavity of the rocket rank of one of the fuel component, and on the other side it is connected through a manifold to the inlet main line of the engine; the cavity of the annular channel is connected through a bent pipeline to the cavity of the rocket tank of the other component; on the other side, this cavity is connected through the manifold to the inlet main line of the engine.

EFFECT: invention provides improvement of reliability, reduction of mass-and-dimensional characteristics.
