Skylab Zero G Flammability Studies

The goal of the study was to obtain photographic data of various combustible materials ignited under controlled conditions in a zero-gravity environment to determine the extent of flame propagation and flashover to adjacent materials, rates of surface and bulk flame propagation under zero-convection, self-extinguishment characteristics, and extinguishment characteristics by vacuum or water spray. The combustion chamber and controls for this experiment are provided by Experiment M512. The combustion chamber is stainless steel with a low emissivity interior. A large opening on one end permits the installation of igniter-fuel assemblies. Chamber connections are provided for venting either to the vacuum of space to exhaust smoke and products of combustion, or venting to the vehicle interior to equalize pressure and to permit opening. Interior work lights are provided as well as means to remove solid ash particles by a vacuum cleaner equipped with a filter trap. Provisions are also made to spray water to evaluate extinguishment by that means. The igniter-fuel assemblies are housed in a separate container which serves both as a protection to the assemblies and as a place to dispose of used assemblies after testing. Data will be recorded on motion picture film to be returned to Earth for analysis. The astronaut will provide voice comments while performing the experiment.
