Aluminized Coding Study for Retrofitting In-Service Slide Materials |
| Author: |
R.J. Cole, G.S. Sims |
| Abstract: |
This report describes the work performed by the BF Goodrich Company, Akron, Ohio under contract to the FAA Technical Center to develop a thermal resistant reflective coating for the retrofit of in-service slides and slide/rafts. The report includes the experimental evaluation of commercially available reflective coatings and paints, ingredient-modification experiments, methods of application, physical properties tests and retrofit cost estimate. The end product of this study resulted in a new aluminum polyurethane coating, BF Goodrich coating KE7620, suitable for retrofit purposes. |

Exhaust Emission Characteristics And Variability For Maintained General Electric CF6-50 Turbofan Engines |
| Author: |
Gary Frings |
| Abstract: |
Five General Electric (GE) CF6-S0 turbofan engines were tested at the GE overhaul facility in Ontario, California, to quantify and determine the variability of the exhaust emission levels. The effects of heavy maintenance on these emission levels were also studied. Only two of the engines tested actually received major maintenance. Consequently, the data collected is limited in quantity. Conclusions, observations, and recommendations are presented based on this limited data base. No correlation of exhaust emission levels and type of maintenance was possible. The exhaust emission levels of carbon monoxide (CO) and oxides of nitrogen (NOx) have been determined; total hydrocarbon (THC) levels are not quantified. The variability of the CO and NOx species is less than five percent, THC variability a almost 30 percent. The engine emissions did not meet the current or proposed federal standards. Ninety percent of the turbine engine exhaust emissions are produced at the idle power mode. The operational parameters for this important (from the stand-point of emission ion data collect ion) mode are vague and should be more defined. The type of fuel used for emission testing has a significant effect on the resultant exhaust emission levels.

Exhaust Emissions Characteristics And Variability For Pratt And Whitney JT8D-7A Gas Turbine Engines Subjected To Major Overhaul And Repair |
| Author: |
Eric E. Becker, Gary Frings, William C. Cavage |
| Abstract: |
Seven Pratt and Whitney Aircraft (PWA) JT8D-7 A turbofan engines were tested at Kennedy International Airport, New York, to evaluate exhaust emissions characteristics and data variability after overhaul. The measured data show that the engines tested did not meet the Environmental Protect ion Agency (EPA) emission standards. A comparison of the measured data, obtained from the seven overhauled engines evaluated under this program, with new engine data obtained from PWA show that there is a great deal of similarity between the two sets of data. Differences shown in this report between new engine and overhauled engine data are due to the quantity of the engines sampled; the new engine data represent a larger sample size. Satisfactory data can be measured by using the test procedures, instrumentation, and equipment defined in this report. |

Special Aviation Fire and Explosion Reduction (SAFER) Advisory Committee |
| Author: |
J.H. Enders, E.C. Wood |
| Abstract: |
The Special Aviation Fire and Explosion Reduction (SAFER) Advisory Committee and its technical supporting groups spent nearly 13 months from May 1979 through June 1980 examining the factors affecting the ability of the aircraft cabin occupant to survive in the post-crash fire environment and the range of solutions available. Having only a limited amount of time available, the Committee confined its examination to large transport category aircraft, reasoning that recommendations developed could provide the necessary guidance for the FAA to address the broader spectrum of airplane and rotorcraft fire safety improvement. During the course of this assignment, certain topics that were outside the scope of the Committee yet have some bearing on aircraft fire in general, were identified but not discussed by the Committee. Some of these topics were felt to be worthy of further examination by the FAA or by some other body of advisors constituted for that purpose. These topics are not addressed in this report. Presentations were made to the SAFER Committee by Committee members, technical supporting groups, the FAA, citizens and private firms. . The broadly-constituted body of information developed and presented to the Committee formed the basis for Committee Findings and Recommendation. The Committee focused its recommendations on solutions or interim improvements |
