Vliegwiel

Flywheel system include its high precision in controlling spacecraft orientation with minimal power consumption. Its maintenance-free operation, due to the lack of moving fluids or mechanical parts, ensures long-term reliability and low operational costs. Flywheels provide high efficiency in momentum storage and can deliver continuous, fine-tuned control over a spacecraft's attitude, making them ideal for missions that require autonomous and cost-effective control. Additionally, their compact design and ability to function without external fuel make them ideal for long-duration missions in deep space or low Earth orbit (LEO). The flywheel system is a proven, robust solution for precise attitude control, offering both cost efficiency and reliable performance for modern spacecraft.

The Flywheel is a mechanical device used in spacecraft and satellite attitude control systems to store and release angular momentum, providing precise control of the spacecraft's orientation. The flywheel operates by spinning at high speeds to store rotational energy. When a change in the spacecraft's orientation is required, the flywheel's rotation is adjusted, either by accelerating or decelerating the flywheel, to produce a torque that alters the spacecraft's attitude. The system is composed of a high-inertia wheel mounted on a bearing and driven by an electric motor. Flywheels are particularly advantageous in spacecraft applications because they offer precise momentum control without relying on consumable fuel. The system is typically maintenance-free, has no moving fluids, and is highly reliable. Flywheels are commonly used in geostationary satellites, scientific missions, and deep space exploration where long-term attitude control is required. Their ability to function without propellant makes them a cost-effective solution for spacecraft that need to maintain their orientation over extended periods without the complexity of traditional reaction control systems.
