A Critical Survey and Analysis of Aircraft Spline Failures.

摘要

The objectives of this program were: (1) to perform a survey and analysis of the current technology in the design and maintenance of aircraft splines, (2) to emphasize reduced maintenance, extended life, and improved reliability, (3) to identify improvement programs for early reduction of maintenance problems, and (4) to forecast technology gaps for long-range reduction of maintenance problems. Survey forms were developed to identify specific spline problem areas. Visits were made to seven Naval Air Rework Facilities, two Naval Air Stations, two Air Force Bases, ARADMAC, two commercial airlines, five equipment manufacturers, and three lubricant manufacturers in an effort to collect all relevant available information. Based upon the information thus obtained, supplemented by the findings from considerable research and development work conducted at SWRI over the past eight years an overall analysis of the problem of aircraft spline failures and their possible means of mitigation was then made.
