The present analysis deals with the ground taxiing of aircrafts and considers, in particular, their turning at rather low speed with very small path radii among obstacles that may be very close to each other, for example inside the hangars or on the flight decks of the aircraft carriers where other planes stand stationary. To succeed in this operation, it is crucial to optimize the path and avoid dangerous collisions or, more generally, the interference in the ground projection between the obstacles and the band enclosing all the point trajectories of the plane. The essential innovation here proposed for this purpose consists in making all the wheels of the undercarriage steerable, assuming electrically motorized struts, and in searching for the best correlation among the steering angles in order to optimize the path. The geometrical and dynamical nonlinearities due to the relatively large steering angles, to the changes of the cornering stiffness with the vertical loads on the wheels and to the inertial and the aerodynamic forces will be included in the analysis. The rollover critical speeds will be calculated on varying the path radius.

目前的分析涉及飞机的地面滑行，并特别考虑到它们以相当低的速度在可能彼此非常接近的障碍物之间以非常小的路径半径转弯，例如在机库内或在飞机的飞行甲板上。其他飞机静止不动的航空母舰。为了在此操作中取得成功，优化路径并避免危险碰撞，或者更一般地说，障碍物与包围平面所有点轨迹的带之间的地面投影干扰至关重要。为此提出的基本创新在于使起落架的所有车轮都可转向，假设电动支柱，并在转向角之间寻找最佳相关性以优化路径。由于相对较大的转向角、转弯刚度随车轮垂直载荷的变化以及惯性力和空气动力引起的几何非线性和动力学非线性将包括在分析中。侧翻临界速度将通过改变路径半径来计算。
