Sunday morning witnessed another spectacle by ISRO as it successfully tested Scramjet rocket engine or the air-breathing engine at Satish Dhawan Space Centre (SDSC) in Sriharikota in Andhra Pradesh.

With this launch, India became the third nation, after America and Australia, to have this technology.

“The mission was successful. Two scramjet rocket engines were tested during the flight. The finer details about the test will be known later,” an official said.

Futhermore, 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 in Sriharikota.

The scramjet rocket 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 oxidizer to be carried along with the fuel.

About Scramjet Engine:

A scramjet, short for supersonic combusting ramjet, is a variant of a ramjet air-breathing jet engine in which combustion takes place in supersonic airflow.

Scramjet rocket engines are a type of jet engine. They rely on the combustion of fuel and an oxidizer to produce thrust.

Similar to conventional jet engines, scramjet-powered aircraft carry the fuel on board, and obtain the oxidizer by the ingestion of atmospheric oxygen.

Rockets, on the other hand, carry both fuel and an oxidizing agent.

This requirement limits scramjets to suborbital atmospheric propulsion, where the oxygen content of the air is sufficient to maintain combustion.

Scramjets are designed to operate in the hyper-sonic flight regime, beyond the reach of turbojet engines, and, along with ramjets, fill the gap between the high efficiency of turbojets and the high speed of rocket engines.

The scramjet engine will be tested on a full-scale RLV, while the vehicle will be tested for its ability to land on a runway, reports said.
