Canfield joint
From Wikipedia, the free encyclopedia
The Canfield joint is a mechanism that allows for full hemispherical motion from whatever connects to it. Invented by Dr. Stephen Canfield of the Tennessee Tech University, this revolutionary joint was developed specifically for spacecraft thrusters and solar panels. Its gimbal mount simplifies the roll maneuver performed when the space shuttle launches and allows for greater overall maneuverability from the Reaction control system.[1]
When applied to solar panels, the Canfield joint tracks the Sun more of the time and will not tangle the power cords attached to them. This is especially valuable to spaceflight when the spacecraft is performing complicated maneuvers. Its applications will be incorporated into the Constellation Program as a key element.[2]
[edit] Advantages Over Fixed Thrusters
- Fewer parts resulting in fewer mechanical failures and less weight
- Twelve fewer thrusters
- Simplifies movement for roll maneuver
- Allows greater maneuverability
