India Achieves Milestone in Next-Gen Hypersonic Missiles Development, Successfully Conducts Ground Test of Scramjet Engine

The Defence Research & Development Laboratory (DRDL), a Hyderabad-based laboratory of Defence Research and Development Organisation (DRDO) recently conducted a successful ground test of a scramjet engine. This test marks a significant milestone in India's development of next-generation hypersonic missiles.

A scramjet (supersonic combustion ramjet) is a type of airbreathing jet engine designed to operate at extremely high speeds, typically greater than Mach 5 (five times the speed of sound). Unlike traditional jet engines, scramjets do not have rotating compressors or turbines. Instead, they use the high speed of the vehicle to compress incoming air before combustion.

Here are some key details of the ground test by DRDO:

1. Test Duration: The scramjet combustor ground test lasted for 120 seconds, demonstrating stable combustion and successful ignition.

 

2. Speed: Hypersonic missiles, powered by scramjet engines, can travel at speeds greater than Mach 5 (five times the speed of sound or more than 5,400 km/hr).

3. Technological Achievements: The test showcased several notable achievements, including an innovative flame stabilization technique that maintains continuous combustion at air speeds exceeding 1.5 km/s.

4. Indigenous Development: The indigenous development of endothermic scramjet fuel, the first time in India, jointly by DRDL and Industry is central to this breakthrough.

The endothermic scramjet fuel offers significant cooling improvements and ease of ignition. The team developed a special manufacturing process to achieve stringent fuel requirements of DRDL at Industrial scale.

A state-of-the-art ceramic thermal barrier coating (TBC) was developed to withstand extreme temperatures encountered during hypersonic flight.

TBC is an another key achievement along side the Scramjet. The TBC developed is designed to withstand extreme temperatures encountered during hypersonic flight. A new advanced ceramic TBC having high thermal resistance & capable of operating beyond melting point of steel has been jointly developed by DRDL and Department of Science & Technology (DST) Laboratory.

Defence Minister Rajnath Singh praised the DRDO and industry partners for this achievement, highlighting its importance for advancing India's hypersonic missile capabilities.

Scramjets are primarily used in experimental and military applications, such as hypersonic missiles and Space planes.
