Design and Development of an Airport Runway Surface Traction Measuring Device

摘要

An airport runway traction measuring device, the surface slip resistance (SSR) tester, was designed and built. The SSR tester can measure brake slip resistance of airport runways at wheel slip ratios from 0 to 100% and at speeds up to 80 mph. The SSR tester was designed to simulate the performance of full-scale aircraft tires. The tread configuration of the test tire enables simulation by a relatively small test device. Selection of test tire and tester parameters are discussed. Design features, including regenerative braking system which permits the stepless variation of the test wheel slip, are described. Development status, vehicle use, and potential improvements are discussed. (Author)
