First Indigenous Expendable Turbojet Engine

Why in News?

Recently, India achieved a major milestone in aerospace technology with the successful development of its 1^st indigenous expendable turbojet engine.

• Designed by – DRDO’s Gas Turbine Research Establishment (GTRE)
• Manufactured by – Azad Engineering, Hyderabad, the engine was formally delivered to GTRE.

Key Features

• Thrust Class – 350 kg.
• Type – Expendable turbojet engine for defence applications.
• Complex Technology – Jet engine technology mastered by only a handful of countries; requires advanced metallurgy, precision engineering, and stringent standards.

Mechanism

• Air Intake and Compression – Air enters the engine and is compressed in stages to increase pressure and efficiency.
• Combustion – Fuel is added to compressed air and burned at constant pressure, raising temperature and energy.
• Turbine – Hot gases spin the turbine, which powers the compressor.
• Nozzle and Thrust – Remaining gases exit through the nozzle at high speed, producing forward thrust by Newton’s Third Law
