Download or read book Evaluation of Washington Aluminum Company Inc Production AM2 Landing Mat written by Cecil D. Burns and published by . This book was released on 1969 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted to evaluate the performance of AM2 landing mat from production-line fabrication. A test section, consisting of two clay subgrade items with different strengths and one sand item, was constructed and surfaced with the AM2 mat. The test section was subjected to traffic representing 1600 operational cycles of an aircraft having a 60,000-lb gross weight with a single-wheel main-gear assembly load of 27,000 lb and a 30-7.7 tire inflated to 400 psi. Based on the results obtained in this investigation, it is concluded that the AM2 mat will sustain 1600 cycles (188 coverages) of uniformly distributed aircraft operations with a 27,000-lb single-wheel load and 400-psi tire inflation pressure when placed on a clay subgrade having a CBR of 4.0 or greater, the AM2 mat will sustain 1600 passes of a 27,000-lb single-wheel load with 400-psi tire inflation pressure applied in a single path when placed on a clay subgrade having a CBR of 4.2 or greater, with slight core damage occurring in a small percentage of the planks, and the AM2 mat will sustain 1600 passes or 188 coverages of a 27,000-lb single-wheel load with 400-psi tire inflation pressure when placed on a loose sand subgrade.

Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted to evaluate three-piece AM2 landing mat. The mat was fabricated from three 8-in.-wide extrusions welded together to form a 2-ft-wide plank. A test section consisting of one sand item and three clay subgrade items with various CBR strength values was constructed and surfaced with the three-piece mat. The test section was subjected to uniform-coverage and single-line traffic representing operations of an aircraft having a 60,000-lb gross weight with a single-wheel main gear assembly load of 27,000 lb with a 30.7.7 tire inflated to 400 psi.

Available in PDF, EPUB and Kindle. Book excerpt: The report describes an investigation conducted to evaluate the performance of a production quantity of XM20 landing mat extruded by Dow Chemical Company, Madison Division, Madison, Ill., and fabricated by Washington Aluminum Company, Enterprise, Ala. The mat, fabricated from 2- by 12-ft extrusions, was similar to AM2 mat except for the method used to attach the end connectors to the main extrusion and a slight change of the cross section of the main extrusion. A test section consisting of one clay subgrade item at a strength of 4 CBR was constructed and surfaced with XM20 mat. The test section was subjected to uniform-coverage traffic representing operations of an aircraft having a 60,000-lb gross weight with a single-wheel main-gear assembly load of 27,000 lb with a 30x7.7 tire inflated to 400 psi.

Available in PDF, EPUB and Kindle. Book excerpt: This investigation was conducted to determine the optimum panel size for the AM2 mat fabricated by Harvey Aluminum Company, Torrance, Calif. The basic AM2 mat was designed to sustain 1600 operational cycles of an aircraft having a gross weight of 60,000 lb with a single-wheel main-gear-assembly load of 27,000 lb and a 30-7.7 tire inflated to 400 psi. A test section consisting of three items with different subgrade strengths and surfaced with three different size mat panels was constructed and subjected to 188 coverages (equivalent to 1600 cycles of aircraft operations) of accelerated traffic of a 27,000-lb single-wheel load with a 30-7.7 tire inflated to 400 pri. The mat was also tested for its ability to sustain 1600 passes of a 39,000-lb single-wheel load applied in a single track to represent the calculated loading that would be imposed on a landing mat during launching of a 60,000-lb aircraft by catapult.

Book excerpt: The study was conducted to compare the performance of aluminum landing mat fabricated by Butler Manufacturing Co. The primary method of comparison was by using CBR design curves which were developed to represent 1600 operational cycles of an aircraft having a 60,000-lb gross weight with a single-wheel, main-gear assembly load of 27,000 lb and a 30-7.7 tire inflated to 400 psi. CBR design curves were also developed for 1600 passes of a 39,000-lb single-wheel load applied in a single track to represent the calculated loading imposed on the landing mat during launching of the 60,000-lb aircraft by catapult.

Available in PDF, EPUB and Kindle. Book excerpt: This investigation was conducted to evaluate the new-profile AM2 landing mat, which was extruded and fabricated by Harvey Aluminum Company, Torrance, Calif. Three methods were used to attach end connectors to the 2-ft-wide main extrusion to form either the 2- by 12-ft or 2- by 6-ft planks. These methods were electron beam welded with inserts (EBI), electron beam welded without inserts (EB), and metal-inert-gas fusion welded without inserts (MIG). Two test sections, each consisting of two clay subgrade items at a strength of 4 CBR, were constructed and surfaced with the new-profile mat. Items 1 and 2 of test section 1 were surfaced with the EBI and EB mat, respectively. Both items in test section 2 were surfaced with the MIG welded mat, where two mat laying patterns were used so that the traffic lane in item 1 did not include any end joints and the traffic lane in item 2 incorporated 20 end joints. Each test section was subjected to uniform-coverage traffic representing operations of an aircraft having a 60,000-lb gross weight with a single-wheel main-gear assembly load of 27,000 lb with a 30x7.7 tire inflated to 400 psi.
