The competition heats up: Using a newly developed suborbital sounding rocket, India today successfully tested its first scramjet engines.
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. Later, the ISRO in a statement said: “With this flight, critical technologies such as ignition of air-breathing engines at supersonic speed, holding the flame at supersonic speed, air intake mechanism and fuel injection systems have been successfully demonstrated.” The scramjet engine designed by ISRO uses hydrogen as fuel and the oxygen from the atmospheric air as the oxidiser.
The real question is whether India can do something that NASA has never been able to do, go beyond tests and get a scramjet engine installed in a rocket and put it to use. NASA’s history is filled with many similar test programs, each hailed as great achievements that will someday revolutionize the launch industry, and then forgotten and shelved.
