d. Reusable Long Vehicle

ANSWER: Reusable Launch Vehicle
 
Following the success of the Reusable Launch Vehicle-TD in the previous month, ISRO is testing a scramjet engine associated with air breathing propulsion
  • Test flight of the indigenously developed scramjet engine will take place at Sriharikota’s Satish Dhawan Space Centre.
  • Called Advanced Technology Vehicle, the test platform will comprise a scramjet engine associated with a two stage sounding rocket- RH 560
  • Vehicle is being characterised and fabricated at VSSC and ISRO Propulsion Complex, Mahendragiri
  • Air breathing engine will be released at a height of 70 km and ignited during coasting phase.
  • Apart from the hypersonic ignition at Mach 6, ISRO sustained the combustion for 5 seconds
  • Maintaining combustion in this condition is a technical challenge as the fuel has to be ignited in milliseconds
