Electric propulsion thrusters are called rocket engines, a feature of which is the conversion of electrical energy into kinetic energy of the thruster beam. Separation of the primary energy source and the actuator (propulsion device) in electric propulsion systems allows obtaining specific impulse values that are significantly higher than in chemical rocket engines.
These thrusters are designed to correct the orbits of artificial Earth satellites and also to study objects of the Solar system, to create means of intercepting space bodies potentially dangerous to the Earth, reusable vehicles for inter-orbital operations in the vicinity of the Earth, etc.
Due to the fact that the transformation of electrical energy from an external source into kinetic energy of the engine beam can occur in several stages, electric propulsion thrusters represent a wide class of devices that differ significantly both in design and in physical processes occurring in them.
Projects of application and development of electric propulsion systems for spacecraft began shortly after the launch of the first satellite.
We are the translation of advanced science to Real in hand technologies.
As a result of many years of work by scientists around the world, several types of electric propulsion thrusters were created, different in design, operation mode and values of thrust and specific impulse, the main ones:
Gas-dynamic acceleration in the nozzle, but unlike liquid propellant rocket engines and solid propellant rocket engine, heating is electric – electricity is only for heating. Now molecular propellants are considered as the most appropriate, for example: NH3 и N2H4
Specific impulse Is=8000-12000 m/s (800-1200 “s”).
- Resistojet: heating from ohmic heater.
- Arcjet: arc heated
with the acceleration of the ion component in the direction of the electric field: for example, plasma-ion thruster and Hall-effect thruster;
with the acceleration of the ion component in the direction transverse both to electric and magnetic fields: for operation in both stationary and pulsed modes – like pulsed plasma thruster
using variable in time perpendicular electric and magnetic fields to accelerate a propellant with no electrode, like Pulsed inductive thruster, and Helicon Plasma Thrusters.
