An Experimental Study of the Pure-Yaw Frequency Responses of the 18 x 5.5 Type VII Aircraft Tires.

Abstract

The steady-state yawed rolling parameters and the frequency responses of the tire forces and moments are obtained for a group of six (6) 18x5.5 type 7 aircraft tires. This group includes tires with rib and dimple tread designs, 8 ply and 14 ply carcass ratings, relatively new and worn tread conditions, as well as radial and bias carcass constructions. With various load, camber, yaw amplitude and frequency test conditions, the results are presented in fifty-nine (59) sets of frequency response curves. The effects of various test conditions are discussed. A comparison of the radial, shimmy, and non-shimmy tires is given. Correlations between the experimental data of the aircraft tires and the well-known stretched string tire model has also been carried out and discussed in the report. (Author)
