Vacuum test rig for fire tests of liquid rocket engines for space applications

Abstract

This utility model is a test bench and can be used for testing liquid rocket engines (LRE) for space applications, with automatic determination of the thermal conditions of LRE components. The technical result of using the proposed utility model is expanded functionality and improved technical characteristics.The links included in the assembly device for sealing the joint are made in the form of an inclined link interacting with the side face of the RON and facing downwards with its apex, and a second rod link pivotally connected to it and configured to be displaced in the axial direction, the cantilever end of the second rod link is connected to a full-circle elastic element located on the disk flange, the shoulder of the inclined link interacting with the side face of the RON and the second rod link displaced in the axial direction are configured to be displaced along mutually perpendicularly oriented guides, the latter are attached to the disk flange, primary measuring transducers are placed in places of the greatest elastic deformations of the full-circle elastic element.
