REVERBERATION CHAMBER Russian patent published in 2017 - IPC F02K9/96 G01R29/08 B64G7/00 

FIELD: physics, instrumentation.

SUBSTANCE: invention refers to radio engineering testing equipment intended for bench tests of spacecraft rocket engines, in particular for electromagnetic radiation measurement. The reverberation chamber comprises a housing, a source of electromagnetic radiation, a measuring antenna, a screen made of electrically conductive material, fastening elements for chamber structure elements attachement to the camera housing, a rotatable re-radiator of electromagnetic radiation, and a re-radiator rotary motion assembly. The screen is located inside the chamber between the electromagnetic radiation source and the measuring antenna. The re-radiator is made in the form of cylindrical shell with slots arranged on its surface. A rocket engine that generates a directed flow of charged particles is used as the source of electromagnetic radiation, and an axially symmetric body of the vacuum chamber is used as the housing. The output channel of rocket engine is oriented in the direction of the longitudinal symmetry axis of the vacuum chamber housing. The re-radiator is located on the side of the rocket engine output channel, and can be rotated about the longitudinal symmetry axis and is connected to the rotary motion assembly. The inner diameter of the re-radiator exceeds the transverse dimension of the rocket engine, and the longitudinal symmetry axis of the re-radiator is oriented along the direction of the charged particles flow motion generated by the rocket engine.

EFFECT: invention improves reliability and accuracy of measurement of electromagnetic oscillations excited by the rocket engine during testing of electromagnetic compatibility with spacecraft radio equipment.
