在进行自动着舰系统设计时,美军标AR-40A是目前较为常用的参考设计准则,但该准则的要求主要针对F-18等IV类飞机提出,并未说明在应用于I类飞机自动着舰系统设计时的适用性。为研究AR-40A在小型飞机自动着舰系统设计时的适用性,针对某型飞机及其尺寸缩比率为4的缩比机进行了全自动着舰系统设计。通过飞机-航母-大气环境综合仿真,选取着舰效果较好的全自动着舰系统设计结果,通过对其频域响应特性曲线分析对比,验证了AR-40A在小型飞机自动着舰系统设计中的适用性。通过原型机、缩比机、F/A-18三者的频域特性对比,提出了准则在应用于小型飞机自动着舰系统设计时应进行的低频段、中高频段划分及幅值、相角带宽频率等关键边界要求的修改建议,拓展了该准则的适用范围。
The US military standard AR-40A is the most commonly used reference design criterion in the design of the automatic cruise system. However, the requirements of this guideline are mainly for Class IV aircraft such as the F-18, but do not indicate that the AR- The applicability of ship system design. In order to study the applicability of the AR-40A in the design of a small aircraft automatic carrier system, a fully automatic ship-to-ship system design was carried out for a certain aircraft and its reduction ratio of 4. Through the comprehensive simulation of aircraft-aircraft carrier-atmosphere environment, the design of the fully-automatic ship-to-ship system with good effect of the ship was selected. By comparing and analyzing its frequency response curve, the AR-40A was validated in the design of the small aircraft automatic ship-to-ship system Applicability. According to the comparison of the frequency domain characteristics of prototype, reduction ratio and F / A-18, the criteria of low frequency band, mid-high frequency band division, amplitude and phase should be put forward when applied to the design of the automatic landing system for small aircraft Corner bandwidth frequency and other key requirements of the proposed boundary changes, expanding the scope of the guidelines.
