writer-photograph- Tom Blotter left and Fred Keifer show models of two kinds of landing mat materials tested at Utah State University for the Air Force Nearlytemporary square model helped prevent buckling of mats as heavy military planed landed Information Service Photo wilderness metal landing mats over the ground surface However in 1970 prototype test landings of a half- million pound C5A transport plane on such a mat caused the temporary strip to buckle Mat panels were separated and thrown into the air Some of the panels penetrated the airplane and endangered the life of the crew Following that experience the US Air Force contracted with the Engineering Experiment Station at Utah State University to begin testing the landing mats with scale models rather than risk continued tests of the C5A itself Using one-seven- scale th models of metal segments linked together to make the landing runways and a model landing gear USU landing gear made simulated landings on the mats The landing gear scaled to the weight of the airplane was accelerated along a horizontal track and then over the crest of a hill to gather speed At about 30 miles per hour it left the cantilevered end of the track and touched down on the model runway Then an operator riding the model braked it to a stop just as an airplane would be handled on a full-siz- e temporary runway ' According to Prof Blotter the tests show at least three ways the temporary runways can be improved Square mat more stable they found that mat segments with an almost square (4 x 45 feet) geometry are First engineers have the tests Their completed reports show how the temporary more stable than rectangular segments such as the 2x12 foot segments that failed in the C5A test landing or a 2 x D foot variation Second they found that laying the segments the long way of the runway rather than across it dynamically runways can be modified to improve the landing mat performance with larger aircraft The USU research team consisted of Professors P T Blotter and Mechanical of the Manufacturing keeping thm from buckling ahead of the landing gear wheels Hundred of times the model Engineering and Vance T Christiansen and

‘This used improved dynamic stability to be beautiful country”’ Third installing tension anchors at the touchdown end of the McLellan said MeLellan is sponsored by runway also helped keep the mat in place and eliminated bow the Cache group of the Sierra Club waves from forming Using these modifications the researchers were able to make hundreds of landings with the model landing gear without failure of the runway Tested under poor conditions “We tested the runway under the worst conditions” Prof Blotter explained For example Alpha Kappa Psi Professional all landings were made in one

he explained “We’ve given the Air Force technical data on the dynamic response of the mat that can be used in coordination with military operations to make Oct Dr Clifford N Matthews professor of
