Thrust measurement of the most advance ion space thruster. This technology is a breakthrough in space propulsion thrusters. The thrust is shown in milligrams. The average thrust level is between 2 and 4mN at 15W supply power with 6kV accelerating voltage, 2.5mA ion current, 85% of ionization of Krypton propellant, ISP is about 10000s. There are fluctuations of the thrust level between 2.5mN and 4.3mN because the thruster produces some special “pumping effect” of the propellant. Also the pipeline of gas supply is too long as the result of the “pumping” effect the pressure of the gas supply fluctuates. The ion/power supply current fluctuation corresponds in right proportionality of the thrust fluctuation. For this measurement a highly sensitive scale is used. The resolution is about 1milligram that corresponds to 10microN. iongaspropulsion is a part of Starskite, www.starskite.com
