Investigation of a Fiber Optic Strain Sensing (FOSS) Distributed Load Calibration Methodology

Completed Technology Project

Project Introduction

Investigation of a Fiber Optic Strain Sensing (FOSS) Distributed Load Calibration Methodology
FOSS is a relatively newer technology that needs to be explored for application to load calibration and loads monitoring efforts. Load calibration opportunities are rare and typically expensive. MQ-9 wing testing in FLL provides a rare opportunity to advance the sate of the art in aircraft load calibrations. Instrument a MQ-9 wing with FOSS and conventional strain gages to measure wing shear, bending moment, torque and section properties along the span. Perform a loads calibration of the wing to determine load equations for measuring wing shear, bending moment, torque, and section properties along the span. Demonstrate through test the viability of developing a more cost effective and faster method of doing wing loads calibration using FOSS technology by comparing a FOSS load calibration test to the traditional technique using conventional strain gages. Utilize existing partnership with KSC Launch Services Program (LSP) to define technology infusion plan to effectively transition real-time flight loads monitoring techniques from aeronautics to space applications.
