FIELD: engine devices and pumps.
SUBSTANCE: stand for testing electric rocket engine operating on iodine working body consisting of vacuum chamber, evacuation system, electric-rocket engine, system for braking jet of iodine plasma released from engine, system for storing and feeding iodine equipped with heaters and connected through valves with electric rocket engine, a device for condensing iodine provided with a cryoagent supply system, and further includes an iodine vapour line. A braking system mounted coaxially with electric rocket engine and provided with cooling circuit has a central body in the form of truncated cone and a receiving cone covering it, which larger diameter faces the outlet section of the electric rocket engine, and the smaller diameter is connected with the iodine vapour line, the end section of which is connected to the device for iodine condensation and configured with a sealed jacket which is hydraulically connected to the cryoagent supply system, a reservoir which internal cavity has an elastic bag for collecting iodine and made of cold-resistant material and adjacent to its inner wall. The method of testing an electric rocket engine operating on iodine working body is thet the jet of iodine that is released from the engine is braked in the braking system and deposited in the iodine condensation device.
EFFECT: invention allows to increase the economic efficiency of stand operation.
