In the field of space science, India created a new history on May 23, 2016 through ISRO (Indian Space Research Organization). He successfully set himself up in the world’s leading 5 countries by conducting a successful test of Reusable Launch Vehicle RLV-TD from the Sriharikota Space Center in Andhra Pradesh at 07:00. This is a launch vehicle that, after installing satellites in orbit in space, will be able to come back to earth like an airplane. This will reduce the cost of sending satellites to space ten times and we will be able to observe satellites in extremely short expenditure.

The point of note is that the Indian Space Institute (ISRO) had thought about this space shuttle about 15 years ago, but started work on this project five years ago. In this way, ISRO has achieved a significant milestone in testing the spacecraft, which looks like a plane of 6.5 m in a very short time from indigenous technology. This specroft is 6.5 meters long, and its weight is 1.75 tonnes. The cost of 95 crores has come to this. With this, ISRO has also made it clear that this is just a test vehicle, it will take 10-15 years to build the real space.

Re-experiment space technology
(Reusable Launch Vehicle Technology):
You would be surprised to know that the reusable technology has been rejected by countries like USA and Russia long ago. Although the project was started under ‘Buran’ project, but after a trial it was terminated. Similarly, the NASA program, which has been discontinued a long time ago, has been discontinued. In such a way, India has made success through this trial and has forced other countries of the world to think in this direction.

Actually, the projection vessels used for space travel / satellite launch are not eligible for reuse. That’s why this program becomes extremely costly. For this reason, Indian scientists started work on the technique of launching the reusable vehicles and earned success on the basis of their dedication and dedication, which is being praised all around.

How does RLV-TD system work?
ISRO made its first formal announcement on January 7, 2015. ISRO tested it on May 23, 2016 by practicing its announcement. In the process of testing, RLV-TD filled the Hypersonic Flight Experiment (HEX) with the help of HS9 Solid Rocket Booster from the Sriharikota Space Center of Andhra Pradesh at 07.00 in the morning.

HS9 burned out after a 91.1 second run of solid fuel powered boosters. So far the spacecraft reached the height of 56 km above sea level. After reaching this height HS 9 and RLV-TD split. After launch, the launch rocket fell into space, but due to its special thermal protection system, the space shuttle landed in its fixed place in the Bay of Bengal, which was destroyed without gliding.

This successful RLV-TD flight was 770 seconds, which was fully controlled by the control system. However, after this test flight, this scale model will not be able to get the sea well, because the device has not been designed with a view to swim in the water.

There are many experiments related to it now. Under their investigation of RBV’s Borbone engine, after landing in the space of the space, the re-landing on the flight on the earth and the Scramjet Propulsion Experiment of the vehicle. Scientists have hoped that these experiments will also be done very well.

Features of RLV-TD spacecraft:
It took about five years to build RLV-TD space and it cost Rs. 95 crores in its construction. The biggest feature of this projectile vehicle is that it is based on indigenous technology and it can be used more than once.

The development and construction of RLV-TD spacecraft involves day-night work of 600 scientists and engineers. After this experiment, this scale model can not be recovered from the Bay of Bengal. Because it has not been made to float in water.

ISRO has prepared the observation vehicle with the help of the Delta Wing. During its observation, it has to be investigated whether the spacecraft is able to glide and navigate at five times faster than the speed of sound or not.

The success of this observation vehicle will significantly reduce the satellite launch cost. Initially it will be used in satellites, but later it can be used in a human mission.

However, it will take about 10-15 minutes for RLV-TD to be fully prepared. But its experimental success is a matter of joy. For this, scientists of ISRO are definitely deserving of congratulations.
