摘要:

燃油箱通气性能计算是通气系统设计过程中的一个重要环节。对某型飞机的通气系统进行了分析,在网络算法和时间微分法的基础上,研究了通气系统供油油箱组和非供油油箱组内空气压力的计算模型,并给出了飞机机动过程中油箱组通气的模拟方法。针对某型飞机油箱通气系统,模拟了某一特定机动过程下,各油箱组内空气压力的变化过程,计算结果用于该机通气系统性能的验证,效果良好。

Abstract:

The vent system must keep the tank pressure within the permitted limits during maneuvering and its performance validation is one indispensable process in the course of system design. On the bases of network algorithm and time differential method, a calculation model is studied for air pressure inside the fuel tanks and a simulation method of vent system in maneuver course is presented.

Key words: maneuvering,  , vent , system,  , air , pressure,  , calculation , model
