As you want to know more about Indian Space Research Organisation, Scramjet technology here I will help you for that.

Here telling you details of technology

The Scramjet technology of Indian Space Research Organisation is an improvement over the ramjet engine as it efficiently operates at hypersonic speeds and allows supersonic combustion which also known as Supersonic Combustion Ramjet, or Scramjet.

Advantages
Does not have to carry oxygen

No rotating parts makes it easier to manufacture than a turbojet

Has a higher specific impulse (change in momentum per unit of propellant) than a rocket engine; could provide between 1000 and 4000 seconds, while a rocket typically provides around 450 seconds or less.

Higher speed could mean cheaper access to outer space in the future

Disadvantages
Difficult / expensive testing and development

Very high initial propulsion requirements
