When aircraft with multi wheel and multi strut turns on the ground, both design methods are uncertain about loads determination and distribution. Based on elastic tire theory and the turning motion model of nose wheel landing gear, a ground turning motion model of multi wheel multi strut landing gear is established. The lateral loads and vertical loads distribution law of each single landing gear is analyzed. The harsh loading landing gears are picked out in combination with stable turning conditions. The analysis results are verified by the result obtained from flight test with the strain method. Lateral loads and vertical loads prediction models of the landing gear are established under two kinds of strategies, which are used to predict the limit turning loads, and finally the prediction result is verified by the measured result. The results showed that the loads direction is opposite between the front main landing gear and the latter landing gear. Compared with the middle landing gear, the magnitude of the main landing gear loads is much smaller than that of the other two. The vertical loads distribution is related to the filling of the landing gear stut, and the distribution ratio of lateral loads is different from the vertical loads. The established landing gear loads prediction models are accurate and can effectively reduce the risk of the aircraft ground limit turning test.
