Abstract:

A method for rating the potential crash fire hazard of gelled and emulsified hydrocarbon fuels was developed since the use of thickened aircraft fuels may provide a significant reduction in the crash fire hazard. The rating system is designed primarily for screening candidate thickened fuels with respect to their overall flammability hazard under laboratory-scale conditions. The fuel properties included in the rating system are minimum autoignition temperature, flash point, volatility rate, self spread rate, regression or burning rate, flame spread rate, and fire ball size under impact conditions methods for determining these fuel properties are also described. Experimental data on such fuel properties are presented for JP-4 and JP-5 or Jet A thickened fuels that were formulated with an emulsifying agent or with one of three different gelling agents submitted for evaluation. The results of these determinations and the numerical ratings derived for each fuel composition are discussed.
