The scramjet engine originally developed and designed in India. The test flight of the originally developed engine gets successful. Moreover, This superjet engine took place from Satish Dhawan Space Centre. This space centre is situated in Sriharikota. This is a research rocket and it is an ATV Designer Vehicle. It is launched from Satish Dhawan Space Centre on Sunday. Additionally, this is ISRO’s first experimental mission. furthermore, The main purpose of ISRO to develop this super jet is to use hydrogen as fuel and the air as the oxidizer.
Important Information: The ISRO Scramjet engine uses Hydrogen as an atmospheric fuel and oxygen as an oxidizer. This prototype was the first test of the ISRO Scramjet engine for brief periods with a Mach 6 hypersonic flight. The ISRO Advanced Technology Vehicle (ATV) was a solid rocket booster used for the supersonic testing of Scramjet engines. Scramjet’s ATV engines at lift-off weighed 3277 kg. It lifted off at 6 a.m. The mission has an easy countdown of 12 hours. ISRO’s chairman and other space scientist are present for this moment.

Advantages of Scramjet Engine
- You don’t have oxygen to hold.
- The manufacturing with no moving components is simpler than a turbojet.
- Has a higher specific momentum (change of momentum per propellant unit) than a rocket engine.
- It can take 1000 to 4000 seconds, whereas a conventional rocket provides about 450 seconds or less.
- In the future, increased speed could lead to less expensive access to outdoor space.
Challenges & Disadvantages
Any of ISRO’s technological challenges in developing the Scramjet engine include the development of Hypersonic engine air intake, the supersonic combustion system, development of very high-temperature materials, computer tools for simulating hypersonic flow, guarantee the engine’s performance and operation over a range of flight speeds, and proper thermal thermal control.
Important Features of a Scramjet Engine
- IT is India’s first original Scramjet engine.
- Further, this rocket is based on an advanced technology vehicle rocket.
- Additionally, two scramjet engines get a successful launch.
- India becomes the 4 countries to test this scramjet engine
- It is an important milestone in the space transportation system
- The scramjet engine usage is during the atmospheric phase.
- Hydrogen used as fuel in the scramjet engine. it would help in bringing down the launch cost.
- Two scramjet engines are hugging the rocket on its sides.
Components & Principles
Given the strategic importance of air intake technology, which can significantly change the launch vehicle configuration, international efforts are underway to improve air intake technology. The three concepts of air respiration engines produced by numerous Space Agencies, Ramjet, Scramjet and Dual Mode Ramjet (DMRJ). A ramjet is a kind of jet respirator that uses the forward motion of the vehicle to compress incoming air with no spinning compressor for combustion. Fuel is injected with heated compressed air in the combustion chamber and ignites.
A ramjet vehicle requires a start-up aid, such as rocket assistance, to propel the traffic to a pace at which it starts pushing. Ramjets operate well at super-sound speeds (3 times sound speed) around 3 Mach and are capable of working up to 6 Mach speeds. However, as the aircraft approached hypersonic speeds, the ramjet performance started to decline. A scramjet motor is an improvement over the ramjet motor since it works efficiently and allows supersonic combustion at hypersonic speeds. So, it’s known as the Ramjet or Scramjet Supersonic Combustion.

Applications of Scramjet Engine
A Scramjet vehicle jet-engine aircraft could drastically reduce the time needed to go from one location to another, possibly putting anywhere on earth on a 90-minute flight. However, there are concerns if such a vehicle can bear adequate fuel to make useful long journeys and heavy FAA aircraft regulations that produce sonic booms in the US world. Therefore, a single stage of a vehicle to tether suggests where a Mach 12 orbital tether can take a payload of around 100 km from a vehicle to carry it into space.
