Chennai: India on Sunday morning successfully tested its own scramjet or the air breathing engine with the launch of a big sounding rocket, said a senior official of Indian Space Research Organisation (ISRO).
“The mission was successful. Two scramjet engines were tested during the flight. The finer details about the test will be known later,” the official not wanting to be quoted told IANS. He said that as scheduled the two stage/engine RH-560 sounding rocket took off from the rocket port located at Satish Dhawan Space Centre (SDSC) in Sriharikota in Andhra Pradesh.
He said the two air breathing engines were like hugging the rocket on its sides and normally when the rocket reaches a height of 11 km the scramjet engines would start breathing air. “The scramjet engines were ignited 55 seconds into the rocket’s flight. The engines were tested for six seconds,” he added. The scramjet engine, used only during the atmospheric phase of the rocket’s flight, will help in bringing down the launch cost by reducing the amount of oxidiser to be carried along with the fuel. –IANS
Scramjet Rocket Engine, which will use oxygen from the atmosphere thereby reducing launch cost, from the spaceport of Sriharikota. “The test fire took place around 6 AM from the Satish Dhawan Space Centre in Sriharikota, it was successful” an official of the city-headquartered space agency told PTI.
Usually rocket engines carry both fuel and oxidiser on board for combustion, but these newly developed engines will use oxygen from the atmosphere and there by reducing the cost.
It also reduces the weight of the vehicle during lift-off, ISRO said.
President Pranb Mukherjee congratulated ISRO for the successful test. “Hearty congratulations ISRO on successful test of futuristic scramjet rocket engine, India is proud of you,” he said in a tweet.
