The JWST (Telescope), with its tennis-court size sunshield, is subject to solar radiation pressure. that exerts a tiny torque about its center of mass (cm). The JSWT attitude-control system uses system of six reaction wheels (RW) to counter this torque. Eight thrusters are available and operate occasionally to dump angular momentum that accumulates in the RW system. The force associated with the radiation pressure is 0.00125 N and its perpendicular offset from the cm is 0.13 m. the angular momentum storage capacity of the RW system is 98 Nms. One thruster provides 4.5 N of thrust, with perpendicular offset from the cm of 1.5 m. For how long do the thrusters need to fire? (5 points) How often do the thrusters need to fire to de-saturate the RW system (to zero) The JWST (Telescope), with its tennis-court size sunshield, is subject to solar radiation pressure. that exerts a tiny torque about its center of mass (cm).
