飞机被击落,不仅与防空武器系统的质量有关,而且也与飞机的易损性有关。所谓易损性,是指在空战中,飞机被发现和受到攻击而损伤的难易程度,即飞机的生存能力。研究易损性问题,不仅有助于改进飞机设计,提高飞机的生存力;也有助于认清目标性质,改进防空武器系统的性能。易损性包括:战术易损性和结构易损性。战术易损性是指被红外、雷达或其他探测器探 Aircraft were shot down, not only with the quality of the air defense weapon system, but also with the vulnerability of the aircraft. The so-called vulnerability refers to the ease of damage that an aircraft is found to be attacked in air combat, that is, the survivability of the aircraft. Studying vulnerability issues not only helps to improve aircraft design and enhance aircraft survivability but also helps to recognize the nature of the target and improve the performance of the air defense weapon system. Vulnerability includes: Tactical Vulnerability and Structural Vulnerability. Tactical vulnerability is detected by infrared, radar, or other detectors
