ISRO's Scramjet Tech: Aerospace Marvel



  Jan 02, 2024

ISRO’s Scramjet Engine Technology



1. What is the scramjet engine technology that ISRO is developing?

Answer: Scramjet engine technology is a type of propulsion that allows engines to operate efficiently at hypersonic speeds (faster than Mach 5, which is five times the speed of sound). Unlike traditional jet engines, scramjets don’t carry their own oxygen; instead, they use the oxygen from the atmosphere to burn fuel, making them lighter and potentially more efficient for high-speed travel.

2. Why is the scramjet engine important for ISRO?

Answer: The scramjet engine can propel vehicles to hypersonic speeds, which is important for both space exploration and defense applications. It allows for more efficient travel and can significantly reduce the cost of launching objects into space.

3. What are the challenges of scramjet engine operation?

Answer: One of the major challenges of scramjet technology is achieving sustained operation at hypersonic speeds, which involves overcoming the drag that acts against the vehicle’s motion. ISRO aims to demonstrate an engine that can produce more thrust than drag, allowing continuous flight.

4. What is ‘Irosene,’ and why is it significant?

Answer: ‘Irosene’ is a domestically developed fuel that ISRO plans to use for its scramjet engine. By using a homegrown fuel, ISRO aims to reduce dependence on imported fuels and enhance self-reliance in the hypersonic domain.

5. How could scramjet engines benefit space exploration?

Answer: Scramjet engines could revolutionize space travel by enabling more affordable and frequent space missions. They have the potential for single-stage-to-orbit vehicles, which can reduce launch costs and complexity.

6. What strategic advantages could scramjet technology provide to India?

Answer: Developing scramjet technology could give India rapid deployment capabilities for troops and materials, improve missile defense systems, and enhance long-range strike capabilities. Mastering this technology could provide India with significant strategic and scientific advantages globally.

These FAQs offer insights into the scramjet engine technology by ISRO, its importance, challenges, and potential benefits for space exploration and strategic defense.
