摘　　要：民用飞机对安全性的要求非常高,尤其是刹车系统,需要能够在各种类型的目标跑道上安全地刹停飞机。飞机刹车系统一般配有蓄压器作为液压能源系统的补充,提供长时间停留刹车能力,还可以提高刹车时的安全性。介绍了民用飞机为了在不同类型跑道上安全着陆,对刹车蓄压器的容积尺寸提出的需求,仿真分析了在不同类型跑道着陆时对刹车蓄压器尺寸的影响关系。结果表明,冰跑道着陆对刹车蓄压器容积尺寸需求最大。Civil aircraft shall be safe enough,especially for brake system,which shall ensure the aircraft can stop safely on any target runways.Brake system usually has brake accumulator as a supplementary hydraulic source.This is used to enhance the safety level during braking,and provide long time parking brake capability.This article introduces the brake accumulator size requirement to meet safely landing on any target runway.Through simulation,the size requirements for brake accumulator landing on different runways are analyzed.The results show that the icy runway landing has the largest brake accumulator size requirement.
