Book excerpt: Landing gear provides an intriguing and compelling challenge, combining many fields of science and engineering. Designed to guide the interested reader through aircraft tire design, selection, and integration to the aircraft landing gear, this book presents a specific element of landing gear design in an accessible way. The author’s two volume treatise, The Design of Aircraft Landing, was the inspiration for this book. The Design of Aircraft Landing is a landmark work for the industry and utilizes over 1,000 pages to present a complete, in-depth study of each component that must considered when designing an aircraft’s landing gear. While recognizing that not everyone may need the entire treatise, Aircraft Tires: Key Principles for Landing Gear Design is one of three quick reference guides focusing on one key element of aircraft design and landing gear design. This volume features tire construction and terminology, mechanics of pneumatic tires, tire performance and modeling as well reviewing undesirable tire behavior. R. Kyle Schmidt has over 25 years’ experience across three countries and has held a variety of variety of engineering roles relating to the development of new landing gears and the sustainment of existing landing gears in service.

Available in PDF, EPUB and Kindle. Book excerpt: An aircraft’s interface with the ground—through its wheels, tires, and brakes—is critical to ensure safe and reliable operation, demanding constant technology development. Significant advancements have occurred with almost all civil airliners entering service with radial tires, and with the Boeing 787 having entered service in 2011 with electrically actuated carbon-carbon brakes. This book is divided into three sections: tires, control systems, and brakes, presenting a selection of the most relevant papers published by SAE International on these matters in the past fifteen years. They have been chosen to provide significant interest to those engineers working in the landing gear field. With almost all current large civil aircraft (and many smaller aircraft) opting exclusively for carbon-carbon brakes, a number of papers addressing the challenges of this technology are included. Papers touching on tire behavior and papers discussing brake control strategies are provided. For those looking for more information on aircraft landing gears, brakes, and tires, the SAE A-5 committee (the Aerospace Landing Gear Systems Committee), which meets twice a year, serves as a useful forum for discussion on landing gear issues and development. A current listing of documents produced and maintained by the A-5 committee is included in the appendix.

Download or read book The Elastic Response of Bias ply Aircraft Tires to Braking Forces written by John A. Tanner and published by . This book was released on 1971 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made to evaluate the elastic behavior of a braked rolling tire and to relate this behavior to the tire characteristics obtained from simple static flexure tests. The study consisted of static and braked-rolling tests of two types of bias-ply aircraft tires and an analysis which related tire reaction to the braking forces. The results of this investigation indicate that the elastic response of an aircraft tire to braking forces can be defined by the displacement distribution along the tire periphery and by the fore-and-aft spring constant. Changes in the rolling radius due to braking can be predicted with reasonable accuracy from elastic measurements of the static free-tread periphery or from elastic measurements within the footprint during low-speed braking, assuming there is no slippage between the tire and the pavement. The results of these tests further indicate that what was heretofore considered as pure tire slippage under braked-rolling conditions may be wholly or in part the result of tire elasticity. The elasticity must be considered in the design or application of efficient automatic braking systems.
Download or read book Aircraft New Tire Standard Bias and Radial written by A-5C Aircraft Tires Committee and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Standard (AS) sets forth criteria for the selection and verification processes to be followed in providing tires that will be suitable for intended use on civil aircraft. This document encompasses new and requalified radial and bias aircraft tires. AS4833 is the industry document supporting TSO C62e. This industry standard applies to both tubeless and tube type aircraft tires. For tube type tires, the diffusion performance capability of the assembly is controlled by the inner tube and not the tire. Since this standard defines the minimum performance capabilities of the tire, and not the inner tube, the diffusion performance threshold defined is only applicable to tubeless tires. It is, therefore, necessary to clarify this standard and to address diffusion for tube type tires under 5.2 and 5.3.10. In addition, 8.3.4 is modified to address incorrect references to other sections within the document.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Information Report (AIR) describes the current process for performing comparative wear testing on aircraft tires in a laboratory environment. This technique is applicable to both radial and bias tires, and is pertinent for all aircraft tire sizes.This AIR describes a technique based upon "wear" energy. In this technique, side wear energy and drag wear energy are computed as the tire is run through a prescribed test program. The specifics that drive the test setup conditions are discussed in Sections 4 through 7. In general, the technique follows this process: A test profile is developed from measured mechanical property data of the tires under study. Each tire is repeatedly run to the test profile until it is worn to the maximum wear limit (MWL). Several tires, typically 5 to 10, of each tire design are tested. Wear energy is computed for each test cycle and then summed to determine total absorbed wear energy. An index is calculated for each tire design. This is accomplished by dividing the total linear inches of wear at the most worn point into the total wear energy. The indexes are then normalized to provide a comparative wear rate.The described technique is not meant to provide an absolute wear rate or wear index because the technique does not produce results that allow the user to say a tire will last for a specific number of landings. However, it does provide a comparative index. It will make a distinction from one tire design to another by indicating a percentage difference in abrasive wear rate under representative operational conditions. The technique has been demonstrated in a number of test programs and is shown to have an extremely high correlation to field data. Supporting data is included in Section 9. AIR5797 has been reaffirmed to comply with the SAE five-year review policy.

Download or read book The Design of Aircraft Landing Gear written by Robert Kyle Schmidt and published by SAE International. This book was released on 2021-02-18 with total page 1092 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aircraft landing gear and its associated systems represent a compelling design challenge: simultaneously a system, a structure, and a machine, it supports the aircraft on the ground, absorbs landing and braking energy, permits maneuvering, and retracts to minimize aircraft drag. Yet, as it is not required during flight, it also represents dead weight and significant effort must be made to minimize its total mass. The Design of Aircraft Landing Gear, written by R. Kyle Schmidt, PE (B.A.Sc. - Mechanical Engineering, M.Sc. - Safety and Aircraft Accident Investigation, Chairman of the SAE A-5 Committee on Aircraft Landing Gear), is designed to guide the reader through the key principles of landing system design and to provide additional references when available. Many problems which must be confronted have already been addressed by others in the past, but the information is not known or shared, leading to the observation that there are few new problems, but many new people. The Design of Aircraft Landing Gear is intended to share much of the existing information and provide avenues for further exploration. The design of an aircraft and its associated systems, including the landing system, involves iterative loops as the impact of each modification to a system or component is evaluated against the whole. It is rare to find that the lightest possible landing gear represents the best solution for the aircraft: the lightest landing gear may require attachment structures which don't exist and which would require significant weight and compromise on the part of the airframe structure design. With those requirements and compromises in mind,The Design of Aircraft Landing Gear starts with the study of airfield compatibility, aircraft stability on the ground, the correct choice of tires, followed by discussion of brakes, wheels, and brake control systems. Various landing gear architectures are investigated together with the details of shock absorber designs. Retraction, kinematics, and mechanisms are studied as well as possible actuation approaches. Detailed information on the various hydraulic and electric services commonly found on aircraft, and system elements such as dressings, lighting, and steering are also reviewed. Detail design points, the process of analysis, and a review of the relevant requirements and regulations round out the book content. The Design of Aircraft Landing Gear is a landmark work in the industry, and a must-read for any engineer interested in updating specific skills and students preparing for an exciting career.

Download or read book Aircraft Tires Service Overload Capability written by A-5C Aircraft Tires Committee and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Recommended Practice (ARP) defines a procedure for demonstrating service overload capability for new, main and nose landing gear, radial or bias tires fitted on multiple wheel landing gear of Part 25 certified aircraft. Many OEMs impose an overload condition on the tire that exceeds the current 1.5 factor required in TSO-C62e. The overload condition described herein is recommended in support of FAR 25.1309 (a) and (b) considering continued safe flight and landing following the loss of load carrying capability of one tire on a multiple tire landing gear. In addition to maximizing safety, economic damage is mitigated by ensuring the remaining tire(s) on a landing gear perform their intended function following the loss of load carrying capability of one tire on a multiple tire landing gear. A service overload test should be a recommended practice to achieve a minimum level of safety for aircraft certified under 14 CFR Part 25.
