ISRO: India’s Reusable Launch Vehicle successfully flight tested
In this experimental mission, the HS9 solid rocket booster carrying RLV-TD lifted off from the First Launch Pad at Satish Dhawan Space Centre, Sriharikota at 07:00hr IST.
After a successful flight of 91.1 second, HS9 burn out occurred. After that both HS9 and RLV-TD mounted on its top coasted to a height of about 56 km. At that height, RLV-TD separated from HS9 booster and further ascended to a height of about 65km.
From that peak altitude of 65 km, RLV-TD began its descent followed by atmospheric re-entry at around Mach 5 (five times the speed of sound). The vehicle’s Navigation, Guidance and Control system accurately steered the vehicle during this phase for safe descent. After successfully surviving a high temperatures of re-entry with the help of its Thermal Protection System (TPS), RLV-TD successfully glided down to the defined landing spot over Bay of Bengal, at a distance of about 450km from Sriharikota, thereby fulfilling its mission objectives. The vehicle was successfully tracked during its flight from ground stations at Sriharikota and a shipborne terminal. Total flight duration from launch to landing of this mission of the delta winged RLV-TD, lasted for about 770 seconds.
In this flight, critical technologies such as autonomous navigation, guidance & control, reusable thermal protection system and re-entry mission management have been successfully validated.
ISRO has acknowledged the support of Indian Coast Guard and National Institute of Ocean technology (NIOT) for the mid-sea wind measurement and shipborne telemetry respectively in this mission.
In a message to A.S. Kiran Kumar, Chairman of ISRO, the President has said, “I extend my hearty congratulations to you and your entire team at the Indian Space Research Organization (ISRO) on the successful launch of India’s first Re-usable Launch Vehicle –Technology Demonstrator (RLV-TD).
Prime Minister Narendra Modi and Vice President M. Hamid Ansari have also congratulated the Indian Space Research Organization (ISRO).
In a message the Prime Minister said:
“Launch of India’s first indigenous space shuttle RLV-TD is the result of the industrious efforts of our scientists. Congrats to them.
The dynamism and dedication with which our scientists and ISRO have worked over the years is exceptional and very inspiring”, the Prime Minister said.
