Effects of Cargo Loading and Active Containers on Aircraft Cargo Compartment Smoke Detection Times

The purpose of this project was to evaluate how smoke detection times are affected when the same quantity of smoke is released in either an empty or fully loaded cargo compartment. It also evaluated the effect on smoke detection times from active cargo containers that produce additional airflow patterns. Active containers are equipped with climate control systems that maintain the containers temperature and humidity for the duration of the flight. Tests were conducted in the main deck cargo compartment of a Boeing 727 and in the aft, below-floor cargo compartment of a B-747SP. Although there was some variability in the test results, in general, the smoke detectors alarmed quicker in loaded compartments than in empty compartments. In addition, the operation of the active cargo containers did not have a consistent influence on smoke detection times for the airflow conditions tested.
