CASE STUDY

ROTOCON Low Noise Slip Rings Have a Signal Quality that Remains Clean At All RPMs

ROTOCON Clean At All RPM's

Challenge

An American based manufacturer of helicopter blades approached Meridian Laboratory with challenges they faced in using conventional brushed slip rings during dynamic testing. The average slip ring creates electrical feedback that was interfering with readings during test trials. By converting their slip rings to ROTOCON low noise slip rings, the manufacturer received a custom made product to alleviate their problems within eight weeks of concept creation.

Helicopter blades require a high degree of accuracy during the quality assurance portion of testing. Helicopter blades rotate at about 350-500rpm, the outer reaches of what most conventional slip rings can tolerate. At these speeds, there is a significant amount of electrical feedback or “noise” created by conventional slip rings, which registers interference in quality tests and skews trial results data. Without accurate assessment of blades in a dynamic test run, which can run for as long as 18 months straight, there can be no assurance that the blades are free from imperfections that could be fatal under non-laboratory circumstances.

Solution

Faced with this challenge, they turned to Meridian Laboratory. Together a custom built ROTOCON slip ring design was rushed from concept to delivery in 8 weeks, despite the very specific needs required and process limitations.

  • The slip ring must be custom fitted to space and size specifications already predetermined by the testing requirements
  • The slip rings must produce no electrical feedback that would interfere with dynamic testing measurements

The requirements created by these constraints were more than a traditional slip ring could have met. From RPM range to range of temperature durability, nothing else besides a ROTOCON could have accomplished the task. The result was a successful round of trials, and quality helicopter blades known to be safe.

    I contacted Meridian Laboratory to obtain a slip ring for my Undergraduate Senior Capstone project. The project required … More a slip ring capable of highspeed data transfer with very little noise to drive an LED bar on a fan to generate images. Sven Krause was very knowledgeable and responsive and helped me figure out what product I needed. He even managed to get the slip ring donated to our team and had great advice on how to integrate it into our project. The project was a huge success thanks to Meridian Laboratory.

    I had a great experience working with Vance Nelson on a batch of custom polyurethane wheels. He provided fantastic design … More and material property advice related to my application and was able to deliver high quality wheels in a fast time frame at a reasonable price. I'd highly recommend working with Vance and Meridian Lab in the future

    I've had the pleasure of working with Meridian Laboratory for the past couple of years, and they have revolutionized … More our product with the parts they created for us. Not only did they create the part, they also gave us advice on which type of material to use, and the combination of those two things has helped us be more efficient and productive.
    Vance has been helpful at every turn, and I look forward to working with him and the team at Meridian Laboratory more in the future. They do superb work.
