Isro develo technology to reuse first and second stages of rocket
Isro研发技术以重复使用火箭的一级和二级部段
NEW DELHI: In a bid to cut cost of satellite launchers, Indian Space Research Organisation (Isro) is working on reusable launch technology for using the first and second stages of a rocket multiple times. To master this technology, Isro is going to conduct an advanced version of the reusable launch technology (RLV) test in June-July.
新德里:为了降低卫星发射装置的成本,印度空间研究组织(Isro)正在研究可重复使用的发射技术,以多次使用火箭的一级和二级部段。为了掌握这项技术,Isro将在6月至7月期间进行可重复使用发射技术(RLV)的高阶测试。
Talking to TOI, Isro chairman K Sivan said, "We are working on a reusable launch technology in order to recover the first and second stages of a rocket so that we can reuse them to cut cost and carry heavier payloads. The first rocket stage will be recovered on a vertical landing spot on the sea like SpaceX has been doing it with its Falcon rocket. However, recovering the second stage is not simple. We are, therefore, develo a winged body like a space shuttle. This shuttle will be attached as a second stage in a rocket. It will carry the top portion of the rocket comprising a satellite or spacecraft to space. Once it injects the satellite in its orbit, the shuttle will glide back to the earth and land on an airstrip like an aircraft." He said the "second stage recovery has never been tried by any other space agency in the world, not even SpaceX".
Isro主席K Sivan在接受《印度时报》采访时表示:“我们正在研究一种可重复使用的发射技术,以回收火箭的一级和二级部段,这样我们就可以重复使用它们,以降低成本和携带更重的有效载荷。”火箭一级部段将在海上垂直着陆点回收,就像SpaceX回收“猎鹰”火箭那样。然而,回收二级部段并不简单。因此,我们正在研制一种类似航天飞机的带翼机体,安装在火箭的二级部段。它将携带由卫星或宇宙飞船组成的火箭顶部进入太空。一旦将卫星送入轨道,该带翼机体将滑翔返回地球,就像飞机一样降落在跑道上。他表示,“其他太空机构从未尝试过二级部段的回收,就连SpaceX也没有。”
Isro had conducted the first demonstration test of India's winged body vehicle on May 23, 2016. Then, the RLV had reached a height of 70 km and was manoeuvred back to earth where it glided down into the Indian Ocean and disintegrated.
印度空间研究组织于2016年5月23日进行了带翼可重复使用运载飞行器的首次演示测试。可重复使用运载飞行器达到了70公里的高度后,经操纵返回地球,滑翔到印度洋并解体。
On the June-July test, Sivan said, "The test will be different this time where a helicopter will take the shuttle to a considerable height and from that height, the winged body will be dropped. The shuttle will then glide back to earth and land on an airstrip." Isro is also planning to conduct a third test of the RLV from the orbit. There is speculation that the landing strip could be made in Andaman and Nicobar islands. However, no final decision has been taken yet.
关于6月到7月的测试,Sivan表示,“这次的测试将有所不同,直升机将把带翼机体带到相当高的高度,带翼机体将从这个高度下降,然后滑回地球并降落在飞机跑道上。Isro还计划在轨道上对可重复使用运载火箭进行第三次测试。有人猜测,跑道可能在安达曼和尼科巴群岛建造。但是,尚未作出最后决定。
Currently, SpaceX rules the Rs 39,000-crore global market of satellite launches. The Elon Musk-promoted US company which had 0% market share in 2009 gobbled up over 50% (projected) of the market share in 2018 mostly because of its reusable technology where it uses first stage rocket multiple times. On the other hand, Isro's share is just 0.6% in the global market. In 2018, Isro had launched PSLV just thrice for foreign satellites. Instead, SpaceX launched Falcon rocket 20 times for commercial purpose. As the market is set to grow to $7 billion (Rs 49,000 crore) by 2024, Isro can grab a significant share if it is able to master the RLV technology.
目前,SpaceX主导着价值3900亿卢比的全球卫星发射市场。埃隆·马斯克推动的这家美国公司2009年的市场占有率为0%,2018年的市场占有率预计将超过50%,主要得益于其可重复使用技术,可多次使用一级火箭。另一方面,Isro在全球市场的份额仅为0.6%。2018年,Isro仅为外国卫星发射了三次极轨卫星运载火箭。相反,SpaceX发射了20次“猎鹰”火箭用于商业途径。到2024年,这个市场将增长到70亿美元(约合4900亿卢比),如果Isro能够掌握可重复使用运载火箭技术,将可获得相当大的市场份额。

Involve and engage private sector in rocket launches where technology maturity has been achieved. The private sector can help making launches more commercial, economic and competitive.
让私营部门参与技术成熟的火箭发射。私营部门可以使之变得更具竞争力,更有经济效益。

Wow exploring reuse of first and second stages of rocket is something which goes as an austerity measure from ISRO and every Indian welcomes the same.

Why cant we di something unique??. We always copy what has been done before and tout that we have leadership position. Even the “chip” developed by IIT Chennai was based on a tehnology introduced in 2000 and defunct now.
When do we change to innovators instead of being learners/copycats??
为什么我们就不能有点创新?总是照搬以前的做法,吹嘘我们的主导地位。
就连印度理工学院钦奈开发的“芯片”,也是基于2000年引入的一种技术。我们什么时候能成为创新者而不是模仿者?

Good Attempt. This is not new to ISRO. Only it has not taken shape till date. The study was conducted in 1989 by Dr.Govindan who has got the president award for Kevlar Fibre discovery in India. Almost 30 years after that it getting shape now.
不错啊。这对ISRO来说并不是什么新鲜事,只是直到现在才初具规模。这项研究是由戈文丹博士于1989年发起的,他曾因在印度发现凯夫拉尔纤维而获得总统奖。30年后的今天,这项技术已经成型了。
