 | Over the past two decades, several fuels have been tested in pulsed detonation engines (PDEs) throughout the world. This research focuses on developing a baseline set of ignition and detonation performance measures for six distinct fuels in air: Hydrogen, ethylene, propane, aviation gasoline (avgas), JP-8, and Fischer-Tropsch JP-8 (S-8). To quantify the ignition and detonation performance, four parameters are examined: Ignition time, deflagration- to-detonation transition (DDT) time, DDT distance, and ... |

| The purpose of the research described herein is to compare the ignition delays in an experimental pulsed detonation engine produced by thermal and non-thermal ignitions. The commercial thermal ignition has a pulse duration of about 1 microsec, whereas the non-thermal ignitions have pulse durations of 100 nanosec. Ignition delay is an important factor, along with fill and purge times, that limit the maximum repetition rate and thrust of pulsed detonation ... |

|
| Current research by the US Air Force and Navy is concentrating on obtaining detonations in a pulse detonation engine (PDE) with low vapor pressure, kerosene based jet fuels. These fuels have a low vapor pressure and the performance of a liquid hydrocarbon fueled PDE is significantly hindered by the presence of fuel droplets. A high pressure, fuel flash vaporization system (FVS) has been designed and built to reduce and eliminate ... |

 | Aviation and air breathing missile fuels are characterized and controlled by specifications and by contract. Specifications for aviation fuels have historically been based primarily on usage requirements as opposed to detailed chemistry. Exceptions would be chemically derived, military fuels such as JP-10, as well as certain other missile fuels. Over the years aviation gasoline (Avgas) has become composed primarily of synthetic components, while turbine fuels are largely straight-run distillates and ... |

| The original release at the BX Service Station was thought to have occurred via the UST appurtenances (i.e., valves, piping) which were replaced in early 1989 (see Exhibit A) (designated as the "UST release"). An inventory record examination revealed that between 200 and 2,000 gallons of fuel had potentially been released prior to the summer of 1987. In 1989, all of the USTs passed tank tightness ... |

| Site S-5 is located behind Building 1618 along the eastern side of the Kelly AFB Flightline. An aqua-fuels system, which is believed to be the major source of contamination at Site S-5, is located in the vicinity of Building 1617. Petroleum products stored in the Building 1617 fuel farm included aviation gasoline (Avgas), jet fuel, control unit calibrating fluid, and waste oils. Potentially, any of these ... |

| Automotive gasoline (Mogas), Aviation turbine fuel (JP-4), and Diesel fuel oil (DF-2) were exposed for two years in 55-gallon steel drums at the USATTC Fort Clayton POL Tank Farm. The number of Mogas samples found failing the distillation, unwashed gum content and color tests increased with increased exposure. Results were basically similar for samples exposed in both shaded and unshaded exposure modes. JP-4 samples exhibited low Reid Vapor Pressure ar ... |
