2.2 High quality measurements for helicopter applications using sensor telemetry

: More and more players on the market try to get in the game of sophisticated helicopter manufacturers. There are several interesting industries that helicopters are needed for. The famous ones like military and air transport for air lifting are now extended by new mobility concepts like the electrical urban air mobility. But all have the same challenges with innovations on drives and transmission leading to many newly designed critical rotating components where temperature, strain, force or acceleration measurements for durability and operational strength need to be exercised. In this paper, MANNER shortly sums up the challenges that come with the engineering and development of a high-quality, high accuracy telemetry measurement system. A system withstanding all environmental constraints and mechanical challenges but being flexible for the customer as well as for the different measurement tasks in every mean. Sample timestamping and data structure need to be taken into account for accurate measurements in such big measurement tasks. The request for IENA and Precision time protocol (PTP V2) has been realized as one way to go with the new generation of telemetry systems. The aim of this paper is to provide the reader a good insight on the challenges of telemetry systems on helicopters and the solutions that have been found to realize a highly reliable, highly accurate yet very flexible measurement system that now is an answer to all measuring tasks on a helicopter.
