Abstract:

The migration of smoke from in-flight fires and possible measures to improve its removal have been studied in ground tests on a Comet 4B. Under normal conditions, smoke generated in various sections in the fuselage followed the air flow and dispersed throughout the fuselage before passing overboard. Biasing discharge to the front or rear affected smoke clearance only slightly but directing the total air supply to the compartment in which the smoke was generated had a beneficial effect locally, at the expense of adjacent cabins. Better clearance might be obtained in a more modern aircraft. Tests in the flight deck showed that, in smoke laden conditions, flight instruments were best viewed with individual illumination in low ambient light. Further work with higher smoke densities is recommended. Author
