"India Achieves Major Breakthrough in Hypersonic Missile Technology”
Statement 1: correct
Scramjet engines operate efficiently at speeds above Mach 5, where traditional jet engines become ineffective. They utilize the high-speed airflow to compress air and achieve combustion, providing higher efficiency at hypersonic velocities.
Statement 2: correct
Endothermic fuels absorb heat during combustion, reducing the overall temperature within the engine. This cooling effect helps prevent engine overheating and enhances ignition, making them suitable for the extreme conditions encountered during hypersonic flight.
Statement 3: correct
DRDO's successful ground test of an Active Cooled Scramjet Combustor for 120 seconds marks a major milestone. It demonstrates India's capabilities in developing advanced propulsion systems for hypersonic missiles, bringing India closer to operationalizing these technologies.
