India's Breakthrough in Hypersonic Technology: DRDL's Scramjet Milestone
| Aspect | Details |
|---|---|
| Why in News? | DRDL successfully conducted a ground test of an Active Cooled Scramjet Combustor for 120 seconds, marking India's first step toward hypersonic missiles. |
| What are Hypersonic Missiles? | Advanced weaponry traveling at speeds > Mach 5 (> 5,400 km/hr), evading air defense systems for rapid and high-impact strikes. |
| Scramjet Engine Role | Air-breathing engines sustaining combustion at supersonic speeds without moving parts, compressing and igniting air during high-speed flow. |
| Key Achievements | - Successful ignition and stable combustion at air speeds > 1.5 km/s. - Novel flame stabilization technique. - Advanced Computational Fluid Dynamics (CFD) simulation tools. |
| Indigenous Scramjet Fuel | - Endothermic scramjet fuel developed by DRDL and Indian industry. - Improves thermal management and enhances ignition consistency. |
| Thermal Barrier Coating (TBC) | - Advanced ceramic composition withstands extreme temperatures. - Specialized deposition methods enhance engine performance and durability. |
| Strategic Implications | Positions India among global leaders in hypersonic technology with advancements in stable combustion, thermal management, and indigenous fuel. |
