T. I. Eklund; FEDERAL AVIATION ADMINISTRATION TECHNICAL CENTER ATLANTIC CITY NJ
|
| The purpose of this analysis is the development of a model that relates polymeric material properties to ignitability. The model is developed for an idealized fire test for ignitability of large-scale aircraft honeycomb panels in a vertical orientation. Transport relations for radiative heat transmission and turbulent mass and energy transfer are applied to an idealized piloted ignition of a vertical aircraft panel. The incident radiative energy required for panel ignition ... |

|
| Authors:
Hector Daiutolo; Charles R. Grisel; FEDERAL AVIATION ADMINISTRATION TECHNICAL CENTER ATLANTIC CITY NJ
|
| Braking tests were conducted to determine if large aircraft tires with laterally-cut sipes in the tread improve the braking performance on a wet surface. A tire with 1/4-inch deep by 3/16-inch spaced sipes showed improved braking performance over the nonsiped tire when tested on a wet surface. The improvement, however, becomes insignificant when the depth of the sipes is reduced to 1/8-inch, and there is no improvement when standing water ... |

Satish K. Agrawal; Hector Daiutolo; FEDERAL AVIATION ADMINISTRATION TECHNICAL CENTER ATLANTIC CITY NJ
|
| Introduction of transverse grooves on runways improves braking and cornering performance of aircraft during operations in wet weather conditions and helps to alleviate hydroplaning. The Federal Aviation Administration (FAA) has recommended 1/4-inch square grooves spaced at 1-1/4 inches for installation on runways where the potential of hydroplaning exists. However, a large number of runways remain nongrooved. The major reasons are the high cost of groove installation and limited evidence as ... |

Gary Frings; FEDERAL AVIATION ADMINISTRATION TECHNICAL CENTER ATLANTIC CITY NJ
|
| Five General Electric (GE) CF6-50 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. ... |
