Abstract:A simulated model of a full-sized aircraft cargo compartment was used to determine the effect of active cargo containers. Physical testing in conjunction with the simulated cargo compartment was used to validate the accuracy of the Fire Dynamics Simulator model which included an artificial smoke generator. The artificial smoke generator is currently used in certification of smoke detectors in aircraft cargo compartments. It consisted of heaters that vaporize oil to create smoke. Arranging cargo containers with the smoke generator gives a baseline for smoke movement in the compartment. The smoke was measured using lasers and light meters which were partially obscured by the moving smoke. Fans were added to the containers as a stand-in for temperature-controlled cargo containers (TCC), also called “active” cargo containers, that had condenser cooling fans.
