Abstract:

Fibre Optic Sensors For Flight Test Instrumentation

One of the main challenges encountered by flight test instrumentation is to offer adequate means to deliver accurately the continuously increasing amount of data requested by design offices while minimizing the intrusiveness on the test vehicles. This contradictory trend applies to all stages of the instrumentation chain: sensing part, cabling, data acquisition units and communication.

Nowadays, new Fibre Optic sensors are gaining ground in various industries due to their unique characteristics. However, their optical interrogation has been very challenging, particularly for the demanding environments found in aerospace applications.

To overcome requirements interlinked between performance and miniaturization, a new innovative fibre-integrated approach is presented in this white paper, with a focus on the reduction and optimization of all necessary materials and components.

This paper aims at highlighting the benefits of Fibre Optic Sensing technology compared to legacy sensing methods as well as sharing an initiative to integrate this technology in an existing compact and modular data acquisition unit compliant with harsh environments.
