N2 - This work is motivated by the need for thermal properties in order to perform thermal stress analysis of aircraft structural members. For the particular titanium-core honeycomb panels of interest, the effective conductivity was previously underpredicted by established theory compared to a steady experiment. In the present study the thermal properties panel were measured by transient heating experiments. The transient data is analyzed with a parameter estimation method, in which a non-linear regression is carried out between the experimental data and a transient finite-difference model of the heat transfer in the honeycomb panel. A lumpedparameter analytical model is also discussed. The experimental results show that effective thermal conductivity agrees with the previous steady measurement, which indicates that additional work is needed to understand why the steady predictive method underestimates the effective conductivity of this type of honeycomb panel.
