A very interesting challenge which give confidence that an optical fibre sensor can be embedded on an aircraft. It has been used for speed and position measurement of blades on a turboprop. Thanks a lot to the Safran Helicopter Engine project team for their trust.
OPTEL-TEXYS tachometers take flight! As part of the EcoPulse™ proof of concept with Daher and Airbus, Safran was in charge of the hybrid electric propulsion system. One of the objectives of the project was to synchronize the speed of the six motors in order to safely manage all the power, and to study noise reduction through propeller synchrophasing. To achieve this, Safran Helicopter Engines (SHE) studied technical solutions from Optel-Texys based on its fiber-optic tachometers. The most important challenge was to accurately measure the position of the six electric motors throughout the entire speed range, combined with the ability to meet two main objectives: performance and reliability during flight, where safety is mandatory. Usually used by SHE for laboratory tests, the Optel-Texys team was able to respond appropriately to specific requests, such as: carrying out a FMEA, as the sensor is also used as a speed control device; qualifying the 152M’s electronics according to the DO160 vibration standard to verify its ability to maintain in-flight performance. Our customer finds that “this technology could be of interest for other aeronautical applications where precision is a key parameter or immunity against EMC emissions such as any alternative electric hybridization system including hydrogen or electric solutions or predictive maintenance applications.” Read the full customer success story here: https://lnkd.in/eD9W8P4u Optel-Texys offer top-of-the-range optical fiber tachometers for the specific field of measurement that meet the quality, reliability and ease-of-use requirements of engineers and test technicians.
