Innovative and Affordable Materials/Concepts for Improving Rotorcraft Slip Ring Reliability

Diamond Antenna proposes to use Roll-Ringr technology and create a form, fit, and function Roll-Ringr replacement for the V22 slip ring. Unlike slip rings with a sliding electrical interface, Roll-Ringsr employ a rolling, non-sliding, electrical interface. The rolling, non-sliding, interface is a non-wearing, metal-to-metal, electrical interface that does not generate wear particles. Because there is virtually no wear, the Roll-Ringr will meet the 10,000-hour operating requirement and the 3000-hour MTBF requirement. Testing to date shows that Roll-Ringsr without maintenance will surpass the V22 life by 40%. In addition, because there is no wear or debris, the Roll-Ringr maintains its electrical characteristics over the life of the product. The Roll-Ringr has the following advantages over slip rings that use brush blocks. 1. No maintenance 2. Long life 3. Consistent electrical parameters throughout the life of the product 4. Low resistance 5. Low noise, i.e. low variation in circuit resistance due to rotation
