Abstract:

Two separate flight test investigations were conducted to evaluate the airplanes stopping capability under various runway surface and tire tread conditions. These tests were made with the 707-123B and the 720-023B airplanes. The program on the 707-123B was conducted to determine The effect of tire tread wear on the airplane braking coefficients available on wet runways, the effect of reverse thrust on the stopping capability of the airplane. The tests on the 720-023B airplane were run to assess The effect of tire tread design on the airplane braking coefficients on wet and dry runway surfaces, and the effectiveness of the thrust reversers as an auxiliary stopping device. Photographs of the tires tested during each evaluation are shown. Measurements were made of the stopping distance with each of the above sets of tires. These data were reduced to an airplane braking coefficient and the mean value for each of the various tire treads are given. Author
