（转载）三哥又一国产神话破灭：Dhruv直升机（已补图说 ...

据《印度斯坦时报》8月6日报道，印度被冠名为国产飞机杰作的“北极星”(Dhruv)型先进轻型直升机(ALH)的神话已经停歇。印度主计审计长公署(Comptroller and Auditor General ofIndia，CAG)披露，该直升机90%的材料都是进口的，大大低于其至少50%的国产预期。该直升机项目总投资210.3亿卢比(约31亿元人民币)。

    报道称，供应商向印度军方交付的74架“北极星”型先进轻型直升机未达到预期效果。曾因过重和发动机动力不达标而被指不合适，这款5.5吨重的先进轻型直升机曾被用来替代陆军和空军的“猎豹”(Chetak)直升机机队。

    印度用动力更强进的Shakti引擎来装备“北极星”直升机的计划落后于进度。印度主计审计长公署表示，这款引擎仍需认证。

    印度斯坦航空公司共持有印度陆军和空军159架“北极星”直升机的订单。印度海军只订了6架这种直升机，觉得其反潜战斗能力不够，正寻求替代品。

    印度主计审计长公署上周四称，“海军和印度斯坦航空之间理解缺乏清晰，该项目13.8亿卢比(月2亿元人民币)的花费还没有对消费者产生任何好处。”

NEW DELHI: After 34 years of development, the foreign component in the "indigenous" Arjun main-battle tank still hovers around 50%. Similar is the case with the still under-development Tejas Light Combat Aircraft, which will even in the future fly on imported engines.

And now, it has come to light that another so-called major indigenous defence project, the twin-engine Dhruv Advanced Light Helicopter (ALH), whose design and development began way back in 1984, is still around 90% foreign.

With the defence ministry floundering to lay the foundations for a robust military-industrial base or cutting-edge defence R&D by involving the private sector in a big way, India will continue to import huge quantities of armaments and military sub-systems for a long, long time to come.

"As against the envisaged indigenisation level of 50% (by 2008), 90% of the value of material used in each ALH is still imported from foreign suppliers," says the latest CAG report, tabled in Parliament on Thursday.

"Even though ALH has been in production for 10 years, Hindustan Aeronautics Ltd has not been able to identify alternative indigenous suppliers," said CAG, which conducted a "performance audit" on the ALH project being run by the defence PSU.

Technical glitches and crashes have also continued to dog the ALH project, which has a sanctioned cost of Rs 2,103 crore till now, putting paid to much-touted ambitious plans to sell the 5.5-tonne helicopter to other countries.

"HAL could not penetrate the international market in the absence of international certification despite showcasing ALH in foreign airshows since 2003 (at a cost of Rs 59 crore). It could not also successfully execute the orders received from the civil market," said CAG.

Even the Indian armed forces, which have inducted around 80 ALHs till now, are not too happy. There has been a huge delay in de-induction of the old Cheetah and Chetak helicopter fleets, adversely affecting operations in high-altitude areas in forward locations.

"The technical requirements finalised in 1979 by Army and IAF have not been fully achieved. The ALH has been found unsuitable for the intended multi-role requirements due to excess weight and limited engine power," said CAG.

The 40 ALHs, inducted by Army under a Rs 1,747 crore contract in March 2006, for instance, cannot fly over 5,000-metre altitude, even though the force had wanted them to have the capability to fly over 6,500 metre. Nevertheless, another Rs 9,490 crore contract for another 105 Dhruvs was inked with HAL in December 2007.

Moreover, the development of a new higher-powered engine Shakti for ALH, in collaboration with foreign company Turbomecca, as well as the helicopter's "weapon system integration version" have both been long delayed.

其实也没有太出人意料的地方，只是前段时间有人用Dhruv的“重大成就”来反讽TG在直升机领域进展的缓慢，特此存证。

直升机的发展涉及大量基础学科和工程应用方面的难题，哪有一步登天的？TG经过这么多年从仿制、改进到自主设计也不过才开始小有成就。三哥靠进口马甲坑蒙拐骗还差的远。

除90%零件靠进口外，Dhruv的整体设计也是在德国MBB的“顾问”下进行的，以下是Dhruv和其原型MBB BK177的对比图

BK117

前者明显是后者的放大型。
