As implementation of the burnthrough rule quickly approached, it was realized that there was a serious lack of availability of the Park Oil Burner that was specified in the Rule. The FAA sought to develop a burner that could be equivalent in performance to the Park Oil Burner and could be easily constructed from readily available materials. Compressed air and pressurized fuel would be used to replace the functions of the electric motor and shaft-driven fuel pump, removing much of the fluctuations caused by variations in voltage supply or environmental conditions, while increasing the level of repeatability and reproducibility.
The initial phase of burner development is primarily focused on providing industry with an equivalent burner in order for manufacturers to be compliant with the Rule. Successive iterations of burner development will be focused on analysis of the physics of the burner airflow, fuel spray dynamics, and combustion chemistry. A thorough understanding of these mechanisms will allow for development of a burner with tighter control of the flame and will be independent of the Park Oil Burner components.
