Book excerpt: The investigation was conducted to evaluate XM20 aluminum landing mat fabricated by Dow Chemical Company, Madison, Illinois. The mat, fabricated from 2- by 12-ft extrusions, was similar to AM2 mat except for minor differences in the cross section of the mat and the method used to attach the end connectors to the mat extrusion. A test section consisting of one clay subgrade item atat a strength of 4 CBR was constructed and surfaced with the 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: The report describes investigations conducted to evaluate two aluminum alloy landing mats. These mats were designated as XM20 and XM20E1, and they are one-piece hollow extrusions fabricated from 6061 aluminum alloy artificially aged to the T6 condition. Investigations consisted of traffic, skid, and laboratory tests to obtain information for use in evaluating the mats for potential use as heavy-duty landing mats. Traffic tests were conducted with the mats placed on a prepared subgrade and trafficked with a rolling wheel load simulating actual aircraft operations. (Author).

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.

Book Synopsis Evaluation of Various Sizes of Harvey Aluminum AM2 Landing Mat by : William B. Fenwick
Download or read book Evaluation of Various Sizes of Harvey Aluminum AM2 Landing Mat written by William B. Fenwick and published by . This book was released on 1966 with total page 84 pages. 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.

Book Synopsis Evaluation of Harvey Aluminum 1- by 12-ft Extruded Light-duty Landing Mat with Symmetrical Butt-type End Connectors by : Hugh L. Green
Download or read book Evaluation of Harvey Aluminum 1- by 12-ft Extruded Light-duty Landing Mat with Symmetrical Butt-type End Connectors written by Hugh L. Green and published by . This book was released on 1972 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation reported herein was conducted to evaluate an extruded aluminum alloy landing mat. The 1- by 12-ft mat is a one-piece hollow extrusion fabricated from 6063 aluminum alloy artificially aged to the T6 condition and weights 2.81 lb per square foot of placing area. The mat panels are interlocked along the sides by means of a hinge-type connector, the components of which are integral parts of the basic extrusion. End connectors, which are composed of 6061-T6 extruded aluminum connectors with integral inserts welded to the basic panel using the electron beam welding method, consist of symmetrical butt-type sections that are secured by a locking bar after individual panels have been joined together. The investigation consisted of laboratory, traffic, and skid tests to obtain information for use in evaluating Harvey mat for poetential use as a light-duty landing mat. (Author).

Book Synopsis Evaluation of XM180 Extruded Aluminum Landing Mat by : C. J. Smith
Download or read book Evaluation of XM180 Extruded Aluminum Landing Mat written by C. J. Smith and published by . This book was released on 1974 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted to evaluate an extruded aluminum alloy landing mat (designated XM180). The mat is a one-piece extrusion fabricated from 6061 aluminum alloy artificially aged to the T6 condition. The mat panels are interlocked along the sides by means of a hinge-type connector, the components of which are an integral part of the basic panel extrusion. End connectors, composed of extruded connectors welded to the basic panel, consist of overlap and underlap sections secured by a locking bar after individual panels have been joined together. The mat mentioned herein was different from modified MX18-B mat in that the inserted tubes in the ends of the mat panels were shortened by 3/4 in. and the amount of metal was increased in the area of the female connector and first cavity adjacent to this connector. The method of attaching the end connectors to the mat extrusion was changed to allow improved welds at the corners. The investigation consisted of traffic, skid, cable roll-over, and laboratory tests to obtain information for use in evaluating the XM180Q mat for potential use as a medium-duty landing mat. The test data reported herein were evauated against the criteria for medium-duty mat as established in the revised Qualitative Materiel Requirement (QMR).

Book Synopsis Evaluation of Harvey Nonwelded Aluminum Landing Mat by : Cecil D. Burns
Download or read book Evaluation of Harvey Nonwelded Aluminum Landing Mat written by Cecil D. Burns and published by . This book was released on 1969 with total page 47 pages. 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).
