Abstract

The Hall-effect thruster KM-88 with nominal power equal to 1600 W and specific impulse more than 2000 s has been developed in Keldysh Research Center. The results of development tests are presented in this paper. The capability of the thruster to endure external impacts (vibration, shocks, transportation loads, changing of negative and positive temperatures, climatic factors) has been shown. The lifetime test has been successfully done with 1000 hour duration. The comparison of obtained results with tests of other thrusters is presented. The levels of loads during tests correspond with requirements called for flight experiments as part of spacecraft.
