BRE

 

Burning Rate Emulator (BRE)

normal gravity flame

Image of a normal-gravity flame ext- ending from a flat burner facing downward at an angle. In this conceptual test, a liquid fuel is being burned with a porous wicking burner.

Unlike the other current ACME experiments, the Burning Rate Emulator (BRE) experiment is focused on fire prevention, especially in spacecraft.  Specifically, BRE’s objective is to improve our fundamental understanding of materials flammability, such as ignition and extinction behavior, and assess the relevance of existing flammability test methods for low and partial-gravity environments.  The burning of solid and liquid fuels will be simulated by using a flat porous burner fed with gaseous fuel.  The fuel flow rate will be controlled based on the measured heat flux (at the burner) and surface temperature, mimicking the dependence of condensed-phase fuel vaporization on thermal feedback.  A small number of gaseous fuels will be used to simulate the burning of fuels such as paper, plastic, and alcohol by matching properties such as the surface temperature and smoke production.
