ISRO Space RLV-TD: Scientists of the Indian Space Research Organization (ISRO) are working on making low-cost reusable launch vehicles. Now ISRO is ready for the first landing experiment of this launch vehicle. Such a launch vehicle is called Reusable Launch Vehicle-Technology Demonstrator (RLV-TD).
Launch vehicle can be reused
ISRO Chairman S Somanath has informed in a conversation with PTI that ISRO is ready for the first runway landing experiment (RLV-LEX) of the Reusable Launch Vehicle-Technology Demonstrator from the Space Test Range located in Chitradurga district of Karnataka. ISRO Chairman S Somnath said that weather monitoring is being done for this.
First runway ready for landing experiment
According to ISRO officials, the RLV wing body will be taken to a height of three to five kilometers with the help of a helicopter and will be released about four to five kilometers before the runway with a horizontal velocity. After release, the Reusable Launch Vehicle will take off at a slow speed, approach the runway and land on its own with the landing gear at an area of Defense Airfield near Chitradurga. For this, new systems like landing gear, parachute, hook beam assembly, radar altimeter and pseudolite have been developed. ISRO launched its first RLV-TD HEX- 01 (Hypersonic Flight Experiment-01) mission was flown with SDSC SHAR on May 23, 2016. It successfully demonstrated critical technologies for design and testing.
Emphasis on reducing cost in satellite launch
With a low-cost reusable launch vehicle, there will be less cost on each space launch and flight. This will give a strong foundation to the possibilities of space tourism in the future. The purpose of development of this technology is to strengthen the hold on the commercial aspect related to space. ISRO chief S Somnath has already said that reusable vehicles are very important not only for the commercial sector but also for the strategic sector. With this, India will also be able to send its payload to space and bring it back safely.
ISRO is working fast in the direction of what kind of launch vehicles can be made in the future and how the cost of the launcher can be reduced. At present, the cost of one launch is 20 thousand dollars per kilogram. ISRO is working towards bringing it to 5 thousand dollars. ISRO currently has two types of launch vehicles. India has been launching its consumer satellites in low earth orbit for many years on its Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV).
Earlier, ISRO Chairman Somnath had said that ISRO will focus more and more on research and development in the coming years to develop the latest technology in the space sector. He also stressed on the need to enhance connectivity between ISRO and scientific organizations in the country so that research and development activities in space technology can be carried out on a large scale.
