Available in PDF, EPUB and Kindle. Book excerpt: Under simulated flight environments, fuel/air ratios at various locations of the ullage space were determined using in-line gas chromatograph measurement. Using the shallow tank experimental data showed that during ascent and cruise portion of the flight profile, uniform fuel/air mixtures were found to exist within the entire ullage volume. Significant fuel/air gradients existed during the descent portion of the flight profile, with mainly air near the vent inlet. Evaporation lag was observed during ascent and level flight when liquid Jet A fuel was maintained at 80 degree F. When the liquid fuel temperature was increased to 120F, evaporation rate was found to be rapid enough that the evaporative lag phenomena was no longer observed. By vibrating the fuel tank, it greatly increased the rate of off-gassing of dissolved air in the liquid fuel. This in turn significantly changed the fuel/air ratio in the ullage space. Two separate and complementary models were developed to predict fuel/air concentrations within the ullage.

This book was released on 1966 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problems associated with flight fires in supersonic transport aircraft include most of the factors present in conventional aircraft as well as some additional problems caused in part by the high temperatures produced by supersonic flight and new design concepts. The possibility that the major fuel storage areas may be in the fuselage poses probelms different from those associated with conventional wing tanks. This study constists of a laboratory investigation in three parts: (1) the study of luminous reactions and flames in the systems JP-4-air, JP-6-air, n-decane-air, and low volatility fuel-air as a function of fuel-air-ratio, temperature and pressure; (2) the investigation of ignition characteristics for these fuel-air mixtures during simulated descent patterns of the SST aircraft; and (3) a determination of the effects of additives on ignition and flame properties of these fuel-air mixtures under condition anticipated for the supersonic transport.

Download or read book Aviation Fuels with Improved Fire Safety written by National Research Council and published by National Academies Press. This book was released on 1997-09-18 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reduction of the fire hazard of fuel is critical to improving survivability in impact-survivable aircraft accidents. Despite current fire prevention and mitigation approaches, fuel flammability can overwhelm post-crash fire scenarios. The Workshop on Aviation Fuels with Improved Fire Safety was held November 19-20, 1996 to review the current state of development, technological needs, and promising technology for the future development of aviation fuels that are most resistant to ignition during a crash. This book contains a summary of workshop discussions and 11 presented papers in the areas of fuel and additive technologies, aircraft fuel system requirements, and the characterization of fuel fires.

This book was released on 1986 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the research conducted by the contractor on airplane engine compartment and fuel tank fire safety research. The value of ground testing, using the Aircraft Engine Nacelle (AEN) and the Simulated Aircraft Fuel Tank Environment (SAFTE) facilities, was clearly evident as the testing proceeded. Extinguishant tests of simulated nacelle fires indicated that current criteria for extinguishant concentration and duration were more than adequate for intact nacelles inert gas generator systems (OBIGGS) revealed that both the permeable membrane and molecular sieve adequately inerted the test fuel tank. However, some minor operational difficulties were experienced with both test units which would have to be corrected prior to producing flight hardware. Keywords: Engine fires; Fuel fires, Fire protection; Inerting; OBIGGS; Halon; Nitrogen enriched air.

Download or read book A Benefit Analysis for Nitrogen Inerting of Aircraft Fuel Tanks Against Ground Fire Explosion written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Cabin Safety Research Technical Group's Survivable Accidents Database was used to identify past worldwide transport aircraft accidents and extract detailed data for those accidents where explosion was an issue in the survivability of the occupants. Each of these accidents was analysed in depth to assess the number of lives and injuries that might be saved if the fuel tanks were protected with nitrogen inerting systems. The objective of this analysis was to assess the potential benefits, in terms of reducing fatalities and injuries, resulting from three methods of aircraft fuel tank inerting. The methods analyzed were ground nitrogen inerting in centre fuel tank only, ground nitrogen inerting in all fuel tanks, and onboard nitrogen inerting in all fuel tanks. Thirteen accidents to transport category aircraft were identified during the period from 1966 to 1995 that may have involved a fuel tank' explosion. A mathematical technique was used to model each accident scenario and a Monte Carlo simulation was used to assess a high, median, and low value for the total achievable benefits.
