Abstract:

An investigation was made to determine the shock and vibration levels that centerline runway lights experience in normal service. The tests were performed 1500 feet from threshold of Runway 13 at the National Aviation Facilities Experimental Center, Atlantic City, New Jersey. The results indicate that the natural frequency of the light assemblies are excited and the magnitudes of these vibrations are considerably above the test amplitudes that have been employed for product evaluation. The purpose of this study was to measure the actual shock and vibration levels experienced by the light fixtures due to aircraft and ground service vehicles and to determine the effect these levels would have on light failure. Additionally it was desired to develop the information necessary to reevaluate the design criteria for these light fixtures. Author
