The invention provides a self-adaptive semi-retractable nose landing gear system of an unmanned training aircraft, which comprises a self-adaptive semi-retractable mechanism, and the self-adaptive semi-retractable mechanism comprises a front wheel fork, a front landing column, a limiting rod, a sliding sleeve and a linear driver; the front lifting support column is mounted on the unmanned aerial vehicle body structure and can axially rotate; the middle of the front fork is rotationally mounted at the lower end of the front lifting column; the sliding sleeve is sleeved outside the front lifting pillar in a sliding manner; the other end of the limiting rod is rotationally connected with the outer side of the upper end of the front wheel fork; a limiting table is arranged on the inner side of the upper end of the front wheel fork, located between the front lifting column and the limiting rod and points to the inner side of the limiting rod. And the linear driver is mounted on the front lifting column and is connected with the sliding sleeve. The device is unique, innovative, simple and reliable, achieves comprehensive utilization of multiple functions, can be used for unmanned coach aircraft nose landing gear folding and unfolding fault simulation training, can also be used for a fixed-wing unmanned aerial vehicle, and serves as a nose landing gear capable of adaptively adjusting and controlling the attack angle of the unmanned aerial vehicle.

    本发明提供无人教练机自适应半收放式前起落架系统,包括自适应半收放机构,所述自适应半收放机构包括前轮叉、前起支柱、限位杆、滑套以及直线驱动器;前起支柱安装于无人机机体结构上并能轴向转动;前轮叉的中部转动安装在前起支柱下端;滑套滑动套设在前起支柱外;限位杆的一端与滑套转动连接,另一端与前轮叉上端外侧转动连接;在前轮叉上端内侧有限位台,所述限位台位于前起支柱与限位杆之间并指向限位杆内侧;所述直线驱动器安装在前起支柱上并与滑套连接。本发明独具创新,简单可靠,达到了一体多功能的综合利用,既可以用于无人教练机前起落架收放故障模拟训练,也可以用于固定翼无人机,作为可以自适应调节和控制无人机迎角的前起落架。
