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.
The A-5 Committee addresses all facets of aerospace landing gears: design, maintenance and in-service experience. It publishes Aerospace Information Reports (AIR), Aerospace Recommended Practices (ARP) and Aerospace Standards (AS) for use throughout the industry. These documents provide current design information, recommended design practices and design standards for landing gear systems. A-5 also provides a forum for presentations on current technology and technical interchanges needed by each engineer to stay abreast of a fast moving field.
A-5 is comprised of three subcommittees: Wheels & Brakes (A-5A), Landing Gear, Struts and Couplings (A-5B) and Tires (A-5C). A-5 is an assemblage of top landing gear engineers from throughout the industry and the world including customers and commercial users. The committees form and modify the various specifications and standards for both military and commercial applications. Benefits from committee participation are knowledge, customer responses and first-hand input into tomorrow's specifications.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
