With the help of a biomechanical neck model, several normal postures of an F-16 pilot were analysed. Measurements of accelerations and head positions were obtained during four flights, including simulated air combat. With the help of a model, muscle forces and joint reaction forces in the neck were estimated. Although at the present stage of research results of calculations must be interpreted carefully, conclusions can be drawn with respect to sitting posture, head position and helmet devices. The backward inclined back rest of the F-16 chair decrease the lordosis of the cervical spine, resulting in reduced calculated forces in the lower cervical spine. In high load situations, calculated maximal forces are of the same order of magnitude as failure loads of vertebrae and estimations of maximum muscle forces. The calculated neck load is increased substantially by the helmet and helmet-mounted devices. This load can be reduced by lightening the helmet or shifting the centre of mass of the helmet backwards.
借助生物力学颈部模型，对F - 16飞行员的几种正常姿势进行了分析。在包括模拟空战在内的四次飞行中获取了加速度和头部位置的测量数据。借助模型，估算了颈部的肌肉力和关节反作用力。尽管在目前的研究阶段，计算结果必须谨慎解读，但仍可就坐姿、头部位置和头盔装置得出结论。F - 16座椅向后倾斜的靠背减少了颈椎的前凸，导致下颈椎计算力降低。在高负荷情况下，计算出的最大力与椎骨的破坏负荷以及最大肌肉力的估计值处于同一数量级。头盔和头盔挂载设备会大幅增加计算出的颈部负荷。减轻头盔重量或将头盔质心向后移动可降低这种负荷。
