Research on Instability and “Jack-Knifing” of Civil Aircraft Towing Taxi-Out System

A new towing taxi-out departure mode has become the preferred choice to replace traditional of civil aircraft due its obvious advantages low energy consumption, emissions, and high efficiency. However, inertia may lead potential lateral instability even “Jack-knifing”, as mass system is concentrated in rear. In this paper, mechanism influencing factors were studied using computer virtual simulation technology taking Boeing 737–400 AM210 tractors research objects. The results show that “Jack-knifing” phenomenon was caused by when sliding speed more than 15 km/h, accompanied slip condition. Furthermore, safety zone, side-show zone jack-knifing defined terms steering angle. Additionally, a created under different airport track conditions analyzing stability system. conclusion study provide theoretical basis reference for safe application mode.
