TEST SYSTEM OF HYDRAZINE-LIQUID THRUSTER

摘要

PROBLEM TO BE SOLVED: To provide a test system of a hydrazine-liquid thruster capable of visualizing and acquiring accurately a fluidization state on a catalyst layer of a propellant.;SOLUTION: This test system of the hydrazine-liquid thruster is equipped with a feed tube 14 for supplying a colored simulated propellant having lower toxicity than hydrazine, an injector cover 16 penetrated by the tip part of the feed tube 14, a cylindrical transparent test cell 18 having one end blocked by the injector cover 16, transparent simulated catalyst particles 28 filled in the test cell 18, and a photographing device 30 arranged outside the test cell 18 and photographing the inside of the test cell 18.;COPYRIGHT: (C)2009,JPO&INPIT
