Ignition of Aircraft Fluids by Hot Surfaces under Dynamic Conditions
Abstract
Data are presented on the ignition characteristics of various aircraft fluids under conditions in which they impinge upon a hot surface in the presence of air flow similar to that possible in an aircraft enclosure. The fluids included two jet fuels (JP-4 and JP-8), two hydraulic fluids (MIL-H-5606 and MIL-H-83282), and an engine oil (MIL-L-7808). Generally, the ignition temperatures decreased with an increase in target diameter or surface area and increased with increasing air velocity. At all test conditions, the ignition temperatures of the fluids were noticeably highr than their minimum autoignition temperatures which are determined in uniformly heated vessels.
