|
 | This report contains the results from the final phase of a three- phase research effort. Phase 1 of this research effort surveyed the procedures used by five aircraft manufacturers to develop maintenance documentation. Several potential human factors issues were identified in the processes used by these manufacturers to develop their maintenance manuals. The issues included the reactive rather than proactive use of user evaluations, the limited use of user input ... |

| This report contains the results from Phase II of a III-phase research effort. Phase I (Human Factors Survey of Aviation Technical Manuals Phase I Report: Manual Development Procedures) of this research effort surveyed the procedures used by five manufacturers to develop maintenance documentation. Several potential human factors issues were identified in the development processes employed by these manufacturers. They included the reactive rather than proactive use of user evaluations, the ... |

|
| An investigation of the temperature and moisture sensitive composite properties was conducted. Results provide an evaluation of the degree of conservatism of the 50 deg F margin from glass transition values commonly used to determine a material system's operational limit (MOL). A series of dynamic mechanical analysis (DMA) and static mechanical tests were performed using specimens conditioned at three relative humidity levels and tested at six different temperatures for two ... |

|
| This report contains the results from Phase I of a three phase research effort. Phase 1 examines aviation industry procedures for developing maintenance technical data. Phase 2 will document user problems with maintenance technical data. Phase 3 will identify maintenance technical data development improvements by applying human factors principles. Five aircraft manufacturers were surveyed regarding company policy, communication, data tracking, user feedback, and error reduction efforts. The five industry participants ... |

|
| This document presents a qualification plan that will provide the detailed background information and engineering practices to help ensure the control of repeatable base material properties and processes, which are applied to both primary and secondary structures for aircraft products using composite materials. This qualification plan includes recommendations for the original qualification as well as procedures to statistically establish equivalence to the original data set. The plan describes in detail ... |

|
| The goal of this project was to develop a horizontal impact sled test laboratory for the National Institute for Aviation Research (NIAR) at Wichita State University to effectively serve the aviation industry relative to aircraft seat performance as well as other aircraft components. The fundamental goal was achieved in the fall of 1992, and the ensuing period has been spent testing with at least five commercial clients, three of which ... |

|
| The proposal which the National Institute for Aviation Research (NIAR) at the Wichita State University (WSU) submitted to the Federal Aviation Administration (FAA) on May 23, 1986, proposed aviation safety research efforts in four areas: crashworthiness; electro-impulse deicing; stall/spin prevention; software reliability. Specific research topics were selected on the basis of a review of FAA research interests, the specialized expertise of WSU research interests, and discussions held with FAA personnel ... |

V. Gondhalekar; J. Chaudhuri; A. Inchekel; J. E. Talia; NATIONAL INST FOR AVIATION RESEARCH WICHITA KS
|
 | A non-destructive X-ray technique, the double crystal diffractometer method, is presented as a tool to investigate the aging and deformation characteristics of aluminum-lithium alloys; this method is extremely sensitive and can be used to measure strains and dislocation densities through the rocking curve half width; X-ray data was used to correlate the different stages of the microstructure during aging and deformation; models were also developed to describe the microstructural behavior ... |
