Download or read book Evaluation of Harvey Electron Beam Welded AM2 Landing Mat AM2 M002 written by Cecil D. Burns and published by . This book was released on 1969 with total page 30 pages. 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.

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.

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.

This book was released on 1972 with total page 0 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).

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: A New York Times Notable Book Winner of the Guardian Fiction Prize Winner of the Irish Times Fiction Award and International Award "A swift and masterful transformation of family griefs and political violence into something at once rhapsodic and heartbreaking. If Issac Babel had been born in Derry, he might have written this sudden, brilliant book." --Seamus Heaney Hugely acclaimed in Great Britain, where it was awarded the Guardian Fiction Prize and short-listed for the Booker, Seamus Deane's first novel is a mesmerizing story of childhood set against the violence of Northern Ireland in the 1940s and 1950s. The boy narrator grows up haunted by a truth he both wants and does not want to discover. The matter: a deadly betrayal, unspoken and unspeakable, born of political enmity. As the boy listens through the silence that surrounds him, the truth spreads like a stain until it engulfs him and his family. And as he listens, and watches, the world of legend--the stone fort of Grianan, home of the warrior Fianna; the Field of the Disappeared, over which no gulls fly--reveals its transfixing reality. Meanwhile the real world of adulthood unfolds its secrets like a collection of folktales: the dead sister walking again; the lost uncle, Eddie, present on every page; the family house "as cunning and articulate as a labyrinth, closely designed, with someone sobbing at the heart of it." Seamus Deane has created a luminous tale about how childhood fear turns into fantasy and fantasy turns into fact. Breathtakingly sad but vibrant and unforgettable, Reading in the Dark is one of the finest books about growing up--in Ireland or anywhere--that has ever been written.
