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: 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.
Download or read book Evaluation of Harvey New Profile AM2 Landing Mat written by Cecil D. Burns and published by . This book was released on 1970 with total page 77 pages. 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.

This book was released on 1966 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted to evaluate the performance, under simulated aircraft loadings, of a guide rail (for use in assisted take-offs) designed for use with Airfield Matting No. 2 (AM2), Kaiser Aluminum Company's AM2 when used in conjunction with guide rail and when used without guide rail, and modified AM2 from Harvey Aluminum, Inc., when used in conjunction with guide rail. It was specifically desired to determine the effect that subgrade strength and soil type would have on the performance of the guide rail and AM2. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This investigation was conducted to evaluate a modified and connector on the AM2 landing mat fabricated by Harvey Aluminum, Inc., Torrance, Calif. A test section, consisting of three clay subgrade items with different strengths and one sand item, was constructed and surfaced with the modified 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.

Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted to evaluate the performance of the 1- and 2-ft-wide Harvey nonwelded aluminum landing mats and to compare the performance with that obtained in previous tests on standard AM2 mat. This landing mat was extruded by the Harvey Aluminum Co., Torrance, Calif. Three test sections were built and surfaced with different shipments or types of Harvey mat. The first and second sections were surfaced with 1- by 6-ft and 2- by 6-ft mat, respectively, each over two clay subgrade items with different CBR strength values. The third section consisted of two items surfaced with 2- by 12-ft and modified 2- by 12-ft mat over a subgrade of the same nominal strength as the lower subgrade strength of the first and second sections. All three test sections were subjected to uniform-coverage traffic, and section one was also subjected to single-line traffic. The traffic represented 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. (Author).

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: The investigation reported was conducted to evaluate the performance of the electron beam welded AM2 landing mat. A test section consisting of a heavy clay subgrade was constructed and surfaced with the electron beam welded AM2 mat, which will be known as AM2 mod 2. 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 mod 2 mat will sustain 1600 cycles (188 coverages) of aircraft operations with a 27,000-lb single-wheel load and 400-psi tire inflation pressure when placed on a subgrade having a CBR of 3.6 or greater throughout the period of traffic, and electron beam welding of the end connectors resulted in considerable improvement in performance of the AM2 mod 2 mat over that of AM2 mat tested previously.

Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to evaluate replacement panels and keylock assemblies as accessories for use with AM2 landing mat in the construction of forward airfields. It was also desired to evaluate the capability of the AM2 mat to withstand traffic when laid in a longitudinal direction. A test section with a 10-CBR subgrade and the AM2 mat laid in both longitudinal and transverse directions, with the accessories included, was constructed and subjected to accelerated traffic of a 27,000-lb single-wheel load with a 30.00-7.7 tire inflated to 400 psi.
