Landing Gear Based Weight and Balance Systems

2019-04-18
WIP
AIR6941
This document outlines historical systems which have used the landing gear as a sensor or installation point for full aircraft weight and balance systems. A number of systems have been developed, installed, certified, and placed in service but few systems remain in regular use. The document will capture the history of these systems, reasons (where known) for their withdrawal from service, and lessons learned.

RECOMMENDED PRACTICE FOR MEASUREMENT OF STATIC MECHANICAL STIFFNESS PROPERTIES OF AIRCRAFT TIRES

1997-01-01
AIR1380A
The static mechanical stiffness properties of aircraft tires are fundamental to any computation of wheel and landing gear shimmy characteristics, and are important guides in anti-skid system and aircraft wheel design. While the mechanical stiffness properties of aircraft tires are frequency sensitive, the static or low frequency values are important because they are the ones most easily obtained by laboratory testing and are most commonly found in literature. The following recommended methods for measurement of such properties are believed to represent practices which will give reliable and repeatable measurements, either at one facility or among different facilities, using equipment which is commonly available in most tire testing installations.

A Guide for the Damaging Effects of Tire and Wheel Failures

2022-07-06
AIR5699A
Consideration for the damaging effects to aircraft from the failure of wheels and tires should be evaluated. This document discusses the types of problems in-service aircraft have experienced and methodology in place to assist the designers when evaluating threats for new aircraft design. The purpose of this document is to provide a history of in-service problems, provide a historical summary of the design improvements made to wheels and tires during the past 40 years, and to offer methodology which has been used to help designers assess the threat to ensure the functionality of systems and equipment located in and around the landing gear and in wheel wells.

Landing Area/Landing Gear Compatibility - A Brief History of SAE/Corps of Engineers Cooperation

2014-12-01
AIR4243A
This document discusses the work done by the U.S. Army Corps of Engineers and the Waterways Experiment Station (WES) in support of SAE A-5 Committee activity on Aerospace Landing Gear Systems. It is an example of how seemingly unrelated disciplines can be combined effectively for the eventual benefit of the overall aircraft system, where that system includes the total airfield environment in which the aircraft must operate. In summary, this AIR documents the history of aircraft flotation analysis as it involves WES and the SAE.

Aircraft Flotation Analysis

2022-12-20
AIR1780B
This document is divided into five parts. The first part deals with flotation analysis features and definitions to acquaint the engineer with elements common to the various methods and the meanings of the terms used. The second part identifies and describes current flotation analysis methods. Due to the close relationship between flotation analysis and runway design, methods for the latter are also included in this document. As runway design criteria are occasionally used for flotation evaluation, including some for runways built to now obsolete criteria, a listing of the majority of these criteria constitutes the third part. The fourth part of this document tabulates the most relevant documents, categorizing them for commercial and civil versus military usage, by military service to be satisfied, and by type of pavement. This document concludes with brief elaborations of some concepts for broadening the analyst’s understanding of the subject.

Landing Gear System Development Plan

ARP1598A
This Aerospace Recommended Practice (ARP) is therefore intended to document the process of landing gear system development. Some of the steps covered are mandatory and others are elective, or dependent upon customer requirements or desires. Economics is a very significant factor and for each analysis or test performed, more confidence and assurance of success is gained, but at a price. Some of the steps are performed as a matter of “good engineering practice” and without special recognition. Others are unique to the particular landing gear system and all together comprise a complete development.
