The aircraft design makes use of "off the shelf" hardware as much as possible and was found to have unusual directional control issues during around operations. The aircraft was involved in numerous pilot-induced-oscillation incidents as well as observed to have unusual directional control reactions to failed main gear tires, a condition that is normally handled relatively easily by conventional aircraft steering control techniques. The behavior of the aircraft's tires had previously been modeled in simulators as a result of approximations provided in 40-year-old reference publications. Since knowledge of the true tire cornering and braking behavior is essential to modeling, understanding, and fixing directional control problems, the United States Navy requested assistance from the NASA Langley Research Center's (LARC) Aircraft Landing Dynamics Facility (ALDF) to define the yawed-rolling mechanical properties of the T-45 aircraft tires. The purpose of this report is to document the results of testing the subject tires at the NASA LaRC ALDF in September 1998. Brief descriptions of the Instrumented Tire Test Vehicle (ITTV) are included to familiarize the reader with the ITTV capabilities, data acquisition system, test and measurement techniques, data accuracy, and analysis and presentation of the testing results.

This book was released on 1974 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fore-aft, lateral, and vertical spring rates of model and full-scale pneumatic tires were evaluated by testing techniques generally employed by industry and various testing groups. The purpose of this experimental program was to investigate what effects the different testing techniques have on the measured values of these important static tire mechanical properties. The testing techniques included both incremental and continuous loadings applied at various rates over half, full, and repeated cycles. Of the three properties evaluated, the fore-aft stiffness was demonstrated to be the most affected by the different testing techniques used to obtain it. Appreciable differences in the fore-aft spring rates occurred using both the increment- and continuous-loading techniques; however, the most significant effect was attributed to variations in the size of the fore-aft force loop. The dependence of lateral stiffness values on testing techniques followed the same trends as that for fore-aft stiffness, except to a lesser degree. Vertical stiffness values were found to be nearly independent of testing procedures if the nonlinear portion of the vertical force-deflection curves is avoided.
Book Synopsis Low-speed Yawed-rolling and Some Other Elastic Characteristics of Two 56-inch-diameter, 24-ply-rating Aircraft Tires by : Walter B. Horne

This book was released on 1954 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The low-speed (up to 4 miles per hour) cornering characteristics of two 56 x 16, type VII, extra-high-pressure, 24-ply-rating tires were determined for a range of vertical loadings, yaw angles, and tire inflation pressures. Locked-wheel drag tests were also made for one vertical-load condition. The quantities measured included cornering force, drag force, self-aligning torque, pneumatic caster, vertical tire deflection, rolling radius, and relaxation length. Some supplementary tests were made which included measurements of tire footprint area, vertical-load-deflection characteristics, and the variation of tire radius and width with inflation pressure.

This book was released on 2018 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. This document outlines a specific approach for testing use one particular facility. Revisions to this document are not anticipated and Five-Year Reviews have been determined to be unnecessary by the subcommittee. Therefore, it was agreed to stabilize this document.
Book Synopsis Low-speed Yawed-rolling Characteristics and Other Elastic Properties of a Pair of 40-inch-diameter, 14-ply-rating, Type VII Aircraft Tires by : Walter B. Horne
Download or read book Low-speed Yawed-rolling Characteristics and Other Elastic Properties of a Pair of 40-inch-diameter, 14-ply-rating, Type VII Aircraft Tires written by Walter B. Horne and published by . This book was released on 1958 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The low-speed (up to 4 miles per hour) yawed-rolling characteristics of two 40 X 12, 14-ply-rating, type VII aircraft tires under straight-yawed rolling were determined over a range of inflation pressures and yaw angles for two vertical loadings. One load was approximately equal to the rated vertical load and the other load was approximately equal to twice the rated vertical load for these tires. Static tests were also performed to determine the vertical, lateral, torsional, and fore-and-aft elastic characteristics of the tires.

Available in PDF, EPUB and Kindle. Book excerpt: This book puts the reader in the pilot's seat for a "day at the office" unlike any other. The Smell of Kerosene tells the dramatic story of a NASA research pilot who logged over 11,000 flight hours in more than 125 types of aircraft. Donald Mallick gives the reader fascinating first-hand description of his early naval flight training, carrier operations, and his research flying career with NASA. After transferring to the NASA Flight Research Center, Mallick became involved with projects that further pushed the boundaries of aerospace technology. These included the giant delta-winged XB-70 supersonic airplane, the wingless M2-F1 lifting body vehicle, and triple-sonic YF-12 Blackbird. Mallick also test flew the Lunar Landing Research Vehicle and helped develop techniques used in training astronauts to land on the Moon.
