简要介绍了军用飞机飞行品质 MIL- STD- 1 797A中有关俯仰轴频域准则的要求和原由。提出了对这些准则的理论计算和模拟试验方法。并以某飞机为例 ,利用所提出的方法 ,对其飞行品质进行了计算和模拟。结果表明 ,所提出的计算和模拟方法是合理的。最后 ,讨论了驾驶员模型形式对俯仰轴飞行品质的影响 The requirements and reasons for the pitch axis frequency domain criteria in military aircraft flight quality MIL-STD-1 797A are briefly introduced. Proposed a theoretical calculation of these criteria and simulation test methods. Taking a certain airplane as an example, the flight quality is calculated and simulated by using the proposed method. The results show that the proposed calculation and simulation methods are reasonable. Finally, the influence of the driver model form on the pitch axis flight quality is discussed
