Scramjet engine designed by ISRO uses Hydrogen as fuel and the Oxygen from the atmospheric air as the oxidizer which will also help in bring down launch costs substantially. Joining a select club of nations, India on Sunday successfully test fired its futuristic Scramjet Rocket Engine using oxygen from the atmosphere that could cut the cost of the launches several fold and help in Indian Space Research Organisation’s bid to design advanced air breathing engines.

The first experimental mission of Scramjet Engine was successfully conducted from the Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh at 6 AM, ISRO said. It described the mission as a “modest” yet important milestone in its bid to design and develop advanced air breathing engines, including ones for its future space transport system.
India is the fourth country to demonstrate the flight testing of Scramjet Engine after the US, Russia and European Space Agency. After a smooth countdown of 12 hours, the solid rocket booster Advanced Technology Vehicle (ATV) carrying the Scramjet Engines lifted off at 6 AM and ending a 300 seconds-flight, touched down in the Bay of Bengal, about 320 kms from Sriharikota, the city-headquartered ISRO said.
The important flight events — burn out of booster rocket stage, ignition of second stage solid rocket, functioning of Scramjet engines for 5 seconds followed by burn out of the second stage — took place exactly as planned, ISRO said. The vehicle was successfully tracked during its flight from the ground stations at Sriharikota.
The Scramjet engine will also be used eventually to power ISRO’s reusable launch vehicle at hypersonic speed. ATV is a two-stage spin stabilised launcher with identical solid motors (based on Rohini RH560 sounding rocket) as the first as well as the second stage (booster and sustainer), ISRO said.
The twin Scramjet engines were mounted on the back of the second stage. Once the second stage reached the desired conditions for engine “Start-up”, necessary actions were initiated to ignite the Scramjet engines and they functioned for about 5 seconds, it said adding that today’s ATV flight operations were based on a pre-programmed sequence.
