Reaction wheel - Wikipedia

A reaction wheel (RW) is used primarily by spacecraft for three-axis attitude control, and does not require rockets or external applicators of torque. They provide a high pointing accuracy, and are particularly useful when the spacecraft must be rotated by very small amounts, such as keeping a telescope pointed at a … Zobraziť viac Reaction wheels are used to control the attitude of a satellite without the use of thrusters, which reduces the mass fraction needed for fuel. They work by equipping the spacecraft with an electric … Zobraziť viac For three-axis control, reaction wheels must be mounted along at least three directions, with extra wheels providing redundancy to the attitude control system. A redundant mounting configuration could consist of four wheels along tetrahedral axes, or a spare … Zobraziť viac • Collins Aerospace, the owner of Ithaco Space Systems, Inc., the builder of the ill-fated reaction wheels for (among others) the Kepler, Zobraziť viac Beresheet Beresheet was launched on a Falcon 9 rocket on 22 February 2024 1:45 UTC, with the goal of … Zobraziť viac The failure of one or more reaction wheels can cause a spacecraft to lose its ability to maintain attitude (orientation) and thus potentially cause a mission failure.
