Hall-effect electric Thrusters

The Hall-effect Thrusters (Magnetic-layer type or Stationary) generate thrust by creating and accelerating ionized working gas over magnetic and electrostatic fields. The LAJP develops and manufactures the Hall thrusters within thrust level 2…100mN. The LAJP has developed a number of Hall thrusters, each of which are capable of a range of power and thrust levels.

Plasma jet propulsion have been studied during many years. Basing on the experience our team started from August, 2007 the commercial developments of the plasma Hall-effect thrusters and propulsion systems using Xenon as a propellant.

HEET-05&10 are designed to support orbits for the satellites, to perform orbit control tasks for small-, mini- and micro-satellites.
