舰载机着舰侧向轨迹增量控制

Delta Ground Track Command of Carrier-Based Aircraft Landing

摘要:

针对舰载机着舰侧向控制难度较大的问题,借鉴美国海军的“魔毯”(MAGIC CARPET)着舰的先进理念,提出了 1种新的着舰控制方法,即侧向轨迹增量控制。首先,分别从理论上分析了侧向常规控制、侧向轨迹增量控制的控制结构和着舰性能；然后,对 HUD显示符号进行改进；最后,通过实时仿真,比较了这 2种方法的着舰控制效果。结果显示,着舰侧向轨迹增量控制具有 3个优点:1)简易,降低了飞行员的操纵频次和负担；2)直观,着舰侧向操纵更直观,侧向杆量与飞机侧偏修正速率成正比例,而且当横杆回中时飞机能自动跟踪跑道中心线的横向漂移；3)鲁棒,显著提高了对侧风和舰尾流的抑制能力,即使在飞行员不操纵的情况下,飞机也能迅速反应和抑制风干扰。因此,建议在着舰工程中采用侧向轨迹增量控制。

Abstract:

In response to the difficulty of lateral control for carrier-based aircraft landing, a novel landing control method, namely delta ground track command, is proposed based on the advanced concept of MAGIC CARPET carrier landing from the US Navy. Firstly, the control structures and landing performance of lateral conventional control and delta ground track command are analyzed theoretically. Then, improvements are made to the HUD display symbols. Finally, the land-ing control effects of these two methods are compared through real-time human-in-the-loop simulation. The results show that delta ground track command has three advantages: (1) Simplicity: reducing the pilot's control frequency and burden; (2) Intuitive: Landing lateral control is more intuitive, with the lateral stick displacement being directly proportional to the aircraft's lateral deviation correction rate, and the aircraft can automatically track the lateral drift of the runway centerline when the lateral stick returns to the center; (3) Robust: it is significant to improve the ability to suppress crosswind and ship air wake. It is recommended to apply delta ground track command during carrier landing engineering.
