Paper Abstract

A temperature sensor network basing on 20 multiplexed fiber Bragg gratings has been developed to perform gas temperature distribution monitoring within the 60-m diameter helium gas fill of a novel cargo airship CL75 for loads of up to 75 metric tons providing a long-term repeatability of temperature measuring results of 0.15 K. The fiber optic temperature sensors overcome problems with lightning protection in the all-plastic airship and allow to measure true gas temperatures through the whole balloon volume. The gas temperature data of the sensor network are used in airship lifting control to improve the flight height stabilization.
