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 Advances in Aircraft Brakes and Tires written by Robert Kyle Schmidt and published by SAE International. This book was released on 2015-08-24 with total page 126 pages. 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 Aircraft Tire Retreading Practice Bias and Radial written by A-5C Aircraft Tires Committee and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Recommended Practice (ARP) sets forth criteria for the selection, inspection, retread and repair of worn civil aircraft tires, and the means to verify that the retreaded tire is suitable for continued service. This document is applicable to both bias ply and radial aircraft tires qualified subsequent to the adoption of this document. ARP4834 is the industry document supporting AC145-4A. 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 7.1.9 and Section 10.

Download or read book Handbook of Aeronautical Inspection and Pre Purchase written by Denny Pollard and published by Trafford Publishing. This book was released on 2005-12-20 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you are a prospective owner, pilot, broker, or aviation mechanic or anyone who needs to know where to find information about the aviation airworthiness, maintenance, inspections and rules---you'll find all he information you need in this one volume. The following expert tips in this book will walk you thought step by step without worrying if you are buying a hangar queen. Every aspect about inspections, mechanic privileges, mechanic and owner responsibilities and what you should look for and inspect when choosing an aircraft. Know where to find the tools to aid in research of the aircraft history, specifications, details on modifications and changes made through the years, Type-Certificate Date Sheets, FAA Airworthiness Directives, Supplementary Type Certificates, Maintenance Alerts for each make and model aircraft, and aircraft records. This book documents the history, experiences and hardships of purchasing aircraft. It describes the difficult and hazardous situations demanding ingenuity, resourcefulness and a lot of difficult hard work. Denny's years of experience in the aviation field demonstrates a lesser-known side of aviation that is from the mechanic's' perspective. This book is the first of its' kind and once started, compels the reader to continue to the last page. Before you buy your next aircraft, have an independent inspection completed by an Airframe and Powerplant mechanic. Whether you are an American or overseas buyer you will be able to buy with confidence with a pre-purchase inspection. With your pre-purchase inspection you should receive an extensive condition report verifying the condition and originality on the aircraft you wish to purchase. The pre-purchase should be able to tell you if the aircraft is currently airworthy, and if the aircraft has been in an accident or been modified. Along with the detailed report you should receive several photographs, including pictures of the fuselage, engine compartment, and interior and close ups of areas of concern. After the inspection, the mechanic or agent for service should discuss this information with you. Are you aware the pre-purchase agreement you sign may be the single most important document, among the dozen or so documents sometimes required? And which specific items should you include in your purchase agreement. Has your aircraft (Or the One That You Are Thinking About Purchasing) been subjected to less than scrupulous inspection and maintenance practices, over the years? Sometimes even a very competent pre-purchase inspection does not include a complete inspection of the aircraft records because it is often very time consuming to read them thoroughly. Positively, the most enlightening pre-buy inspection is a good evaluation of the aircraft maintenance records. A complete evaluation will identify the current status of the aircraft as required by 14 CFR 91.417, uncover time frames of no maintenance, or lack of maintenance, identify inaccurate engine cycle tracking as well as aircraft time tracking and reveal aircraft damage history. Prospective purchaser is responsible for discovering discrepancies that can only be revealed by in-flight evaluation such as flight characteristics, proper functioning of navigational instrumentation, avionics and autopilot. The purpose of the Pre-purchase Inspection is to protect the interest of the buyer; it is not intended to be an Annual/Airworthiness Inspection.

Download or read book Aircraft Tire Wear Profile Development and Execution for Laboratory Testing written by A-5C Aircraft Tires Committee and published by . 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 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.
