Contactless and high rotational speed sensor data transmission
A maintenance-free, fast-rotating measuring system for a wind tunnel model capable of handling 8400 rpm. No such system existed yet, although it was required back in 2013 to conduct measurements with the wind tunnel model for the Z-08 Counter-Rotating Open Rotor (CROR), a next-generation concept for sustainable engines that can significantly reduce fuel consumption and CO2 emissions. To address this, NLR developed a highly advanced measuring system with a Contactless Rotating Power and Data Transfer (CRPDT) module, for which it has now been granted a patent. With the CRPDT module, NLR has cleared the way for ever higher rotational speeds, not only for wind tunnel models but also for airborne on-board applications.
