Engine Model: Cold Gas Thruster Module. Propellants: Nitrogen gas. Thrust(vac): 111 N (25 lbf). Isp: 68 sec. Mass Engine: 0.0860 kg (0.1890 lb). Diameter: 0.0254 m (0.0833 ft). Length: 0.0635 m (0.2083 ft). Chambers: 1. Chamber Pressure: 138.00 bar. Thrust to Weight Ratio: 132.55. Country: USA. Status: In Production. 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.. Manufacturer: Parker Bertea Aerospace. Operating Pressure Range: 136 - 13.6 atm. Thrust at 136 atm: 4.5 - 111.2 N and 8.9 - 55.6 N. Voltage: 28(4 Vdc. Response Time: 8 millisec max. Mass: 0.086 kg per thruster. Size: 25.4 mm diameter X 63.5 mm per thruster.
