Book excerpt: Assessment of current technology for collecting and analyzing longitudinal runway profiles to recommend a method for Transport Canada use. Runway longitudinal profile data for 5 runways were collected using a Digital Incremental Profiler, along with that for 4 other runways, and were analyzed using surface profile - travelling straight edge, root mean square vertical acceleration, and international roughness index methods. Each of the pavement profiles was analyzed using the runway roughness analysis program, an MS-DOS software program. A complementary field study was completed to allow correlation between the roughness values measured using the portable universal roughness device, the maysmeter, and the riding comfort index procedures and the 3 methodologies.

Available in PDF, EPUB and Kindle. Book excerpt: Runway roughness as it affects aircraft response and human comfort was analyzed, and two human failure criteria approaches were investigated. Although generally unsatisfactory, human-absorbed power as a criterion for roughness was found to be informative for locating severe rough areas. A third-octave band approach to establish human criteria acceleration levels was more accurate. However, this approach revealed that aircraft response data were usually far below the criteria levels for human comfort, even on runways known to be rough. Because of the lack of suitable criteria, a statistical analysis of both the roughness and the aircraft response data was performed. In this manner, profile roughness was placed on a relative basis. Statistical techniques were then described whereby both overall and detailed profile roughness properties could be classified. The establishment of detailed roughness statistics was considered incomplete, and additional work was recommended in this respect. (Author).

Book excerpt: This paper briefly summarizes the more important statistical data obtained by the NACA on the subject of ground loads. The information presented relates primarily to landing-impact and taxiing loads; however, some limited data are also presented on one phase of ground-handling loads, namely, braking friction. A number of experimental and theoretical papers dealing with various aspects of the subject are listed in the bibliography.

Available in PDF, EPUB and Kindle. Book excerpt: The ability to accurately predict the dynamic response of an aircraft while it is operating in the taxi mode depends, in part on the correct modeling of the dynamic characteristics of the landing gear system. Traditionally, landing gear have been designed to absorb landing impact ('shock absorber') and their characteristics during periodic, oscillatory response ('spring') have been considered as secondary. With the increased emphasis on the rough or damaged field taxi operation, there is a requirement to determine the best methods for modeling the gear system. This report documents a brief review of the state of the art of gear modeling. A study was then conducted to evaluate important model parameters, using a simple cantilevered gear computer simulation. Also included is the development of a technique for the experimental determination of important gear system parameters. (Author).
