Abstract: |
In order to study the operating performance of LHT-100 Hall thruster (diameter 100mm) belonging to Lanzhou Institute of Physics in the wide power range,LHT-100 Hall thruster was operated in the wide power range,that is,for operating conditions spanning 100~400V discharge voltage and 500~1800W discharge power. The operating parameters of LHT-100 Hall thruster were investigated experimentally. The experimental results show that,LHT-100 Hall thruster may operate in the extended power range. The discharge feature and thrust of LHT-100 Hall thruster are stable. Thrust varied from 30~95mN,specific impulse from 600~1950s,efficiency from 0.18~0.53,and power to thrust ratio from 14.3~18.4W/mN. |
