Thrusters (LRE of small thrust) are intended for generation of steering forces in order to change attitude of space vehicles in orbit.
thruster of 100 N
thruster of 30 N
thruster of 30 N
Their advantages are:
• low mass and overall dimensions
• increased pressure tightness
• high response
• long service life
• high reliability
• operation in both continuous and pulse modes
• consumption of saturated and unsaturated propellants
• availability of pressure annunciator for telemetry control of the thruster operation.
