一、序言众所周知,世界上大多数火山喷发时产生的流动熔岩、火山石、泥石流和落下的尘埃都可能使当地居民的生命和财产受到损失。鲜为人知的是,由火山喷发产生的火山灰细小的颗粒进入大气层后形成的浮云也可能威胁飞行安全。近年来,随着全球经济的高速增长和航空科技的进步,飞机方便快捷的特点越来越得到人们的喜爱,因此,飞机已成为一种重要的运输工具,全球的飞行量有所增加,从而使飞机遭遇火山灰云的报告也有所增加。人们已认识到火山灰如坏天气(湍流、对流云、雾和低云)一样,不仅威胁飞行安全,而且给航空公司和民航系统造成经济损失。本文着重介绍国外在这方面的研究及咨询服务的运作。二、火山灰对航空器造成的主要损坏火山灰对航空器造成的损坏主要有以下几种情况: 1.发动机受损火山灰的熔点为600℃～800℃,而飞机在飞行时,其发动机内部的温度超过1000℃,所以吸入 I. Preamble As we all know, the flow of lava, volcanic rocks, mudslides and falling dust from most of the world’s volcanic eruptions can cause the loss of lives and property of local residents. It is little known that clouds of clouds of volcanic ash emanating from volcanic eruptions that form into the atmosphere can also threaten flight safety. In recent years, with the rapid growth of the global economy and the advancement of aviation science and technology, the aircraft has become more and more popular due to its convenience and convenience. Therefore, the aircraft has become an important means of transportation. As a result, the global flight volume has increased, Reports of aircraft encountering volcanic ash clouds have also increased. People have come to realize that volcanic ash, like bad weather (turbulence, convective clouds, fog and low clouds), not only threatens flight safety but also causes financial costs to airlines and civil aviation systems. This article focuses on the foreign operation of research and consulting services in this area. Second, the main damage caused by volcanic ash on the aircraft Volcanic ash damage to the aircraft mainly in the following situations: 1. Engine damage volcanic ash melting point of 600 ℃ ~ 800 ℃, while the aircraft in flight, the engine internal temperature exceeds 1000 ℃, so inhaled
