- Canfield joint
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 spacecraftthruster s and solar panels. Itsgimbal mount simplifies theroll maneuver performed when thespace shuttle launches and allows for greater overall maneuverability from theReaction control system . [ [http://www.nasaspaceflight.com/content/?cid=4182 Nasa Spaceflight “CEV revolution mounted”] ] When applied to solar panels, the Canfield joint tracks theSun 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 theConstellation Program as a key element.

* Fewer parts resulting in fewer mechanical failures and less weight
* Twelve fewer thrusters
* Simplifies movement for roll maneuver
* Allows greater maneuverabilityReferences
