Periodic Reporting for period 3 - HADES (HADES - Optical Hot Air Leak DEtection System)
Berichtszeitraum: 2020-07-01 bis 2020-12-31
The POC2 was finalized and prepared for testing at the LTS site, as soon as the TRL of 4 was approved and COVID allows travelling. NKTP prepared a remote support for the test campaign, without any NKTP personnel from NKTP at the LTS site. Therefore, the spare parts (second chipset for testing) was used to establish a system for deep analysis and error testing during the potential remote test campaign.
The test-campaign however was cancelled due to missing the TRL of 4, as originally anticipated. LTS confirmed a great step forward for fiber optical sensing technologies in the aircraft industry.
This project has shown a great improvement in fiber based monitoring system, proving a spatial resolution of at least 2.5cm with a high interrogation speed and alarm processing. It also shows the capability of absolute temperature measurement, which improves the current system, by showing also the real temperature along the whole air bleed system in addition to the alarm triggering capabilities.
This approach is able to set new standards for distributed monitoring and security standards. Localizing a defect, such as a hot air leak in a light carbon structures, that fast and accurate can decrease the probability of consecutive faults and the down time for maintenance and repair works. This can lead to a safer and cheaper operation of aircrafts.
In addition, this technology can be used in a broader industry, where the precise spatial resolution is of importance, such as the process industry.
