本文用谱分量描述法计算了预定各状态中 A 机和 B 机的各种响应量的统计特性并进行了比较。此外还考虑了自动驾驶仪对紊流作用的改出能力。本文还选用了“乘客舒适性”评定法判定了两机的乘座品质。计算结果表明,小航程晴空紊流情况下,A 机的所有状态及 B 机的大部份状态均是“舒适”的。大航程晴空紊流中,两机的大部份状态均近于“非常舒适”。巡航飞行范围内A 机的各种响应特性变化甚微,且在晴空紊流情况下,巡航飞行范围内都具有良好的响应特性。在风暴紊流巡航飞行中是“不舒适的”的。对于小航程风暴紊流情况起飞过程是“不舒适”,大航程风暴紊流情况起飞过程是“非常不舒适”,所以应避免于风暴紊流中起飞。
In this paper, the statistical properties of the various responses of A machines and B machines in each state are calculated and compared by spectral component description method. In addition, the autopilot’s ability to divert turbulence was also considered. This article also chose the “passenger comfort” assessment method to determine the ride quality of two machines. The results show that all the states of aircraft A and most of the aircraft B are “comfortable” under the condition of small-flight clear-air turbulence. In large turndown, most of the two machines are close to “very comfortable.” A variety of response characteristics of aircraft A cruise flight range changes little, and in the case of clear air turbulence, the cruise range has good response characteristics. It is “uncomfortable” in storm turbulent cruising flights. The take-off process is “uncomfortable” for small-range turbulence turbulence conditions and the take-off process for large turbulent turbulence conditions is “very uncomfortable” and should therefore be avoided during storm turbulence.
