India’s AMCA Programme Takes Flight: A Stealth Leap into the Future of Air Combat

By
In a major leap toward self-reliance in defense technology, India is set to develop its very own fifth-generation fighter jet—the Advanced Medium Combat Aircraft (AMCA) . In a historic move, Defence Minister Rajnath Singh has approved an innovative execution model for the indigenous stealth fighter programme. This model brings together Hindustan Aeronautics Limited (HAL) and private industry players in a competitive framework, marking a significant shift in how India approaches military aviation manufacturing. This bold initiative comes at a critical time, as China has already fielded two fifth-generation fighters , and reports indicate it will supply 40 J-35 stealth jets to Pakistan . Against this backdrop, fast-tracking the AMCA has become an urgent national security imperative.

DRDO’s Scramjet Engine Breakthrough: A Step Towards Hypersonic Missile Systems

The Defence Research and Development Organisation (DRDO) successfully conducted a 120-second ground test of an active-cooled scramjet combustor at its Hyderabad-based Defence Research and Development Laboratory (DRDL). This is a major achievement in India's quest for hypersonic propulsion technology, essential for developing next-generation missile systems.

What is a Scramjet Engine?

A Scramjet (Supersonic Combustion Ramjet) engine is a type of air-breathing jet engine designed to operate efficiently at hypersonic speeds (Mach 5 and above). Unlike conventional jet engines, scramjets do not have rotating compressors and instead rely on supersonic airflow for compression and combustion.

Key Highlights of the DRDO Test

1. Successful 120-Second Ground Test

  • Conducted by DRDL, Hyderabad.
  • Validated the performance of an active-cooled scramjet combustor.
  • Key milestone in the development of India’s hypersonic missile program.

2. Role of Endothermic Scramjet Fuel

  • Endothermic fuels absorb heat during combustion, improving engine cooling.
  • Enhances thermal management and ease of ignition at high speeds.
  • Ensures sustained supersonic combustion, crucial for long-range hypersonic flight.

3. Benefits of Scramjet Technology

  • Eliminates the need for onboard oxygen storage, reducing missile weight.
  • Highly efficient at hypersonic speeds, enabling long-range strike capabilities.
  • Provides sustained thrust at speeds greater than Mach 5.
  • Enhances India's defense capabilities by enabling faster, more maneuverable weapons.
How Scramjet Engines Work?
  1. Air Intake: The engine takes in supersonic airflow as the vehicle moves forward.
  2. Compression: Incoming air is compressed due to the engine’s shape (without rotating components).
  3. Fuel Injection: Supersonic air mixes with the injected fuel (endothermic fuel).
  4. Combustion: Fuel burns in the supersonic airflow, producing high-speed exhaust.
  5. Thrust Generation: The expanding exhaust gases generate thrust, propelling the vehicle at hypersonic speeds.
Applications of Scramjet Technology
  • Hypersonic Cruise Missiles: Capable of flying at Mach 5+ speeds.
  • Space Launch Vehicles: Reduces the cost of launching satellites.
  • High-Speed Military Aircraft: Future fighter jets with hypersonic capabilities.
  • Space Exploration: Potential use in interplanetary missions for fast space travel.
India’s Hypersonic Program and Global Context
  • India has been actively developing hypersonic propulsion technology under DRDO and ISRO.
  • In September 2020, India successfully tested the Hypersonic Technology Demonstrator Vehicle (HSTDV).
  • Nations like USA, Russia, and China are also investing heavily in hypersonic weapons and spaceplanes.
Future Prospects and Impact on National Defense
  • Boosts India’s deterrence capability by enhancing missile speed and evasiveness.
  • Enables long-range precision strikes with minimal detection time.
  • Paves the way for hypersonic spaceplanes and next-gen military technology.
Conclusion

DRDO’s successful scramjet combustor ground test is a game-changer in India’s pursuit of hypersonic technology. It brings the country one step closer to developing cutting-edge hypersonic missile systems and achieving self-reliance in advanced defense technologies.

Manasvi: IIT Delhi’s Bold Step Toward Empowering High School Girls in STEM

By
In a world increasingly shaped by technological advancement, ensuring gender equality in STEM (Science, Technology, Engineering, and Mathematics) is no longer a choice—it’s a necessity. Recognizing this, the Indian Institute of Technology (IIT) Delhi launched a pioneering initiative titled ‘Manasvi’ , a STEM mentorship programme for high school girls . The programme, unveiled in New Delhi today, is spearheaded by the institute’s Academic Outreach and New Initiatives Office . Manasvi is not merely an educational engagement; it is a transformative platform aimed at inspiring and empowering young girls to pursue careers in STEM, fields traditionally dominated by men. At the heart of Manasvi lies the ambition to address the deep-rooted gender disparity in STEM education and careers . Despite producing the largest number of science graduates globally, India continues to see disproportionately low female representation in STEM careers —a statistic that underscores the urgent need for su...
