On the 28t August, India tested its own scramjet with the launch of a rocket successfully and became the fourth country in the world to accomplish this task. It was the first experimental mission of Indian Space Research Organization and the mission was aimed at realization of an Air Breathing Propulsion System that uses hydrogen as a fuel and uses oxygen from the atmosphere as the oxidizer.

Isro’s Advanced Technology Vehicle was used for this testing. It is an advanced sounding rocket and the rocket weighed 3277kg during the lift-off.

The testing was done from the launch pad of SathishDhawan Space Centre which is also known as Sriharikota Range and is located at Sriharikota in Andhra Pradesh.

It was said that the two air-breathing engines that was in the Advanced Technology Vehicle rocket started air when it reached a height of 11 kilometers. The ATV vehicle touched the ground down at Bay of Bengal at a distance of 320 kilometers from Sriharikota after around 300 seconds.

The ISRO said that with this success technologies like ignition of air-breathing engines at supersonic speed, air intake mechanism, holding the flame at supersonic speed and fuel injection system have all been successfully demonstrated. They also mentioned that the scramjet engine helps a lot in reducing the launch costs by cutting down the amount of oxidizer that needs to be carried along with the fuel of the rocket.

The scientists of the ISRO also mentioned that all the events relating to the test like burn out of booster rocket stage and functioning of scramjet engines, etc. all took place at the scheduled time. The two stage/engine RH-560 sounding rocket took off from the port at 6am, as scheduled.

It has also been said that this demonstration is a subtle but an important milestone in the aim of designing and developing an advanced air breathing engine. It is great achievement for the ISRO in their effort for their future space transportation system plans. India is now all boosting its success as they become the fourth country in the world to have successfully tested the scramjet engine.
