Flywheel satellite
WebDue to the micro-vibration of flywheels, the imaging quality of a high-resolution optical remote sensing satellite will be deteriorated, and the micro-vibration effect on the payload is complicated, so it is essential to establish a reasonable and accurate theoretical simulation model for it. This paper presents a method of full-closed-loop time-domain integrated … WebIn the case of Kepler, one of the four reaction wheels was lost because of erratic friction over several months. In an exercise of caution, mission managers switched off Kepler's reaction wheels for 10 days in January, hoping the break would redistribute lubricant inside the wheel assemblies, reducing friction and allowing the units to cool down.

Aluminum flywheels are used in some vehicles. An aluminum flywheel is lighter in weight than a steel flywheel, allowing an engine to shift faster. Aluminum flywheels expand at twice the rate of steel, so they must be tightened properly at ambient temperatures to ensure optimum functionality when the engine is running.
WebExplanation and analysis of the use of reaction wheels in satellites and in the ESAT Nanosatellite. WebThe flywheel's infrastructure should be more inflexible especially around 90-100 Hz. For this target high resolution optical satellite, there should be effective damping measures around 48.6 Hz, 190.4 Hz and 285.4 Hz to decrease the flywheel disturbance to guarantee the high precision of the satellite.
