ISRO - Important Notes
The Indian Space Research Organisation (ISRO) is going to test indigenously developed scramjet engine technology based on air-breathing propulsion in July 2016. The test will be conducted on test platform named Advanced Technology Vehicle (ATV) from the Satish Dhawan Space Centre at Sriharikota. Key Facts The test platform ATV will comprise a scramjet engine hitched to a two-stage sounding rocket (RH- 560). The vehicle has been characterised and being fabricated at the VSSC (Vikram Sarabhai Space Center) and the ISRO Propulsion Complex, Mahendragiri. The air-breathing engine of ATV will be released at a height of 70 km and ignited at hypersonic speed during the coasting phase. Apart from the hypersonic ignition at Mach 6, ATV’s capability to sustain the combustion for 5 seconds will be also tested. The test is expected to help ISRO to achieve good thrust value with the scramjet engine as maintaining combustion in hypersonic conditions poses technical challenges.The Reusable Launch Vehicle Program was launched by ISRO in 2016. It aims to cut down the launch cost by reusing the spacecraft. So far, the RLV (Reusable Launch Vehicle) has been tested over water. For the first time, ISRO will test in land. The RLV will function as a space shuttle that will carry a payload to space and glide back to the earth. While returning, it is to land like a normal aircraft. The landing of the RLV is to be tested at Challakere in Chitradurga district in Karnataka. Highlights The Aeronautical Test Range has 2.2 km runway The RLV will be dropped from a helicopter The test is critical to India’s Human Space Flight program – Gaganyaan. The following four aspects of the RLV are to be tested Hypersonic flight Autonomous landing Powered Cruise flight Hypersonic Flight with air – breathing propulsion. There are two stages in the recovery process. The first stage is similar to that of SpaceX’s Falcon 9 booster. The second stage is an advanced version of RLV testing done in 2016.
