Abstract : This report contains the results of engineering tests conducted on the LARC-XV-IX. The objective of the tests was twofold: (1) to determine the adequacy of modifications incorporated after completion of the original engineering tests performed by the contractor and (2) to determine whether the modifications comply with the military and technical characteristics. The tests conducted on the LARC-XV-IX were divided into three main categories: static, performance in water, and performance on land. In addition, supplemental tests were conducted to determine (1) the LARC's dynamic stability, (2) the adequacy of the gydrqulic system, (3) the degree of torsional vibration, and (4) the engine horsepower. Testing was not as complete as was desired because of weather and lack of time. The mofifications to the LARC-XV prior ot the supplemental tests proved satisfactory. Also, subsequent modifications for stability and for hydraulicsystem reliability appeared satisfactory (although the usual 1,000-hour test was not completed). Therefore, it is concluded that the production design for the LARC-XV, based on these modifications, will meet most of the military and technical characteristics. (Author)
