国产TA600大型水陆两栖飞机水动能研发试验获得成功

2017-08-14 17:51:57   国际在线

国际在线报道(记者殷欣、柳青、王德禄):据新华社消息,近日国产大型灭火/水上救援水陆两栖飞机TA600(也称AG600)成功完成水动性能研发试验,为该型飞机水上首飞奠定了重要基础。专家认为,研制大型水上飞机,有助提高中国水上搜救能力。

TA600是中国正在研制的水陆两栖飞机,最大起飞重量可达50余吨,最大航程超过5000公里,最大功率6300马力。它将满足中国森林灭火、水上应急救援任务的需要。

据了解,此次TA600水上飞机的水动性能研发试验是在航空工业高速水动力航空科技重点实验室进行的。研究人员通过拖曳装置,分别在平静水面和波浪水面条件下,对一架1:10比例的TA600飞机模型进行了测试,以获取飞机在不同速度条件下的吃水、俯仰姿态以及拉力等参数。由于这些数据涉及水上飞机的飞行安全性,因此这次实验对于国产水上飞机首飞能否成功至关重要。《现代舰船》杂志主编、军事专家崔轶亮说水上飞机要在水上起降,所以水动性能实验不可或缺:“它是一个速比模型,它进行这个实验的意义就非常大。你不做这个实验就解决不了水上起降的安全性的问题。”

水上飞机拥有较长的发展历史,在第一次世界大战后到二战期间曾经被广泛运用于军事、民用领域。特别是在跨越大洋的远程飞行方面,可以经常发现水上飞机的身影。中国海军在组建之初就曾经从前苏联引进过一批别-6型水上飞机,加挂鱼雷、水雷、深水炸弹和炸弹,用来执行反潜巡逻、远程预警、海上救援、运输等任务。1968年,中国开始研制首个国产大型水上飞机水轰-5,并于1976首飞成功。

然而随着喷气式路基飞机在航程、载荷方面所展现出的优势越来越明显,水上飞机变得越来越小众。军事专家崔轶亮说:“一个是喷气式航空技术的普及,很多民用飞机都开始使用喷气式技术之后,速度、安全性(问题)都解决了之后,逐渐对水上飞机形成了很大的冲击。因为那个(喷气式)可以飞得更远。到现在的情况下,水上飞机(的)用途比原来萎缩了很多。”

尽管水上飞机一时难以重现昔日的无限风光,但凭借着水上起降的优势,目前大型水上飞机仍然在某些特殊场合发挥着不可替代的作用。军事专家崔轶亮指出:“海上搜救时,有时飞机速度快能发现,但假如你不能水上降落的话,你的飞机就只能干看着,没办法降下去把那人救上来。(另外)无论军用还是民用,有些岛屿,离本土比较远的这种,这个情景下,水上飞机还是最好的一个解决方案。”
