俯仰敏捷性评估与影响因素研究

建立了现代高机动性能战斗机俯仰敏捷性仿真计算数学模型和机动飞行时的操纵动作，以Ｆ－１６战斗机为例，计算并讨论了初始飞行状态以及飞行控制系统参数对战斗机俯仰敏捷性的影响。结果表明，选择适当的飞行状态，有利于更好地发挥飞机的俯仰敏捷性；降低飞机整体系统的阻尼，将有利于提高飞机的俯仰敏捷性；控制系统有关参数的设计，除考虑飞行品质要求外，还需综合考虑飞机敏捷性等方面的要求。

A STUDY OF ASSESSMENT AND EFFECTIVENESS OF FIGHTER PITCH AGILITY

This paper presents mathematical models and control laws in maneuvering flight for simulating the pitch agility of modern high maneuverable fighter. Pitch agility of a sample F-16 fighter is calculated and some factors,such as reference states and flight con-trol system,effecting on fighter pitch agility are discussed.The results show that choosing proper flight condition will be benefit to develop fighter pitch agility,reducing the damping of fighter integral system will improve its pitch agility and designing flight control system should consider requirments of fighter agility besides requirments of flying qualities.
