PURPOSE: A micro thrust measuring device for an artificial satellite thruster is provided to obtain thrust accurately by measuring the displacement of the thruster with a laser displacement measuring device. CONSTITUTION: A micro thrust measuring device for an artificial satellite thruster comprises a base plate (100), a fixing table (110), a rotating bar (200), a support unit (210), a laser displacement measuring device (300), and a weight loading unit (400). The base plate is seated on the ground surface or the top surface of a working table. The fixing table is fixed on the top surface of the base plate perpendicularly. The upper part of the rotating bar is joined to the top surface of the fixing table, and the lower part thereof is moved horizontally. The support unit is installed in the lower part of the rotating bar, and the thruster is placed on the support unit. The laser displacement measuring device senses the movement of the support unit in a horizontal direction. The weight loading unit applies loads of weights (430) successively on the support unit. |
