Book Description
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.

Book Description
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.

Book Description
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.

Book Description
A study is presented of pneumatic tires which are of interest to aircraft designers. The principal topics discussed are tire vertical-force-deflection characteristics; lateral, fore-and-aft, and torsional spring constants; footprint-area properties; relaxation lengths; rolling radius; cornering force, cornering power, self-alining torque, and pneumatic caster for yawed rolling conditions; effects of wheel tilt; and tire radial growth under the influence of centrifugal forces.
