Control Thrusters
The module is designed to provide triaxial attitude control for small
launch vehicles. The module itself comprises three cold gas thrusters
operated by integral independent solenoid valves. The central thruster
generates 111.2 N and the two lateral thrusters provide 55.6 N, each when
operated with a 136 atm dinitrogen gas supply. Each has an Isp of 68 sec.
The solenoid valves are pilot operated and have a response time of <5
millisec at max gas inlet pressure.
