Modern aircraft, due to their large size, structural flexibility and higher take-off and landing speeds, can be excited into a resonant condition by runway profile roughness. Forces generated by the interaction of the aircraft and the runway can produce poor aircraft ride quality, and cause damaging stresses both in the aircraft structure and the runway pavement itself. Wavelength components in the runway profile that cause aircraft resonance often are difficult to identify, isolate, and repair. Advancements in high speed profile measuring systems and the development of a computer simulation of an aircraft responding to the measured runway profile have now provided the ability to identify runway evaluation profile features contributing to poor aircraft ride quality. The research effort covered by this report evaluates the measuring capability of one high speed profile measuring system, evaluates the methods of analysis developed in the project, and applies the measuring and analysis methods to the maintenance, repair and rehabilitation of airport runways.
