Web23. nov 2024 · The reaction wheels cause the spacecraft to react to the spinning action of the wheels. Here’s one way to visualize how reaction wheels work: Imagine you are sitting in a swivel chair and lift your feet off the floor so that you are free to rotate. If you jerk your torso one direction, the chair and your legs will rotate the opposite direction. WebReaction wheels are the most common approach for small spacecraft. Gyroscopes are the most common approach for medium to large spacecraft. Reaction wheels are simpler mechanically and computationally, making them more cost effective and reliable.

Web26. apr 2010 · The working principles of RW, CMG, and VSCMG are very similar. When a torque is exerted on the wheel, an equal and opposite reaction torque is applied to the spacecraft. RWs are electric motor driven rotors made to spin in the direction opposite to that required to re-orient the spacecraft [22,23]. Their limitations are bearing friction and ...
