Hindustan Aeronautics Limited (HAL) officials have revealed the rationale behind the development of a unique engine thrust system for India's Advanced Medium Combat Aircraft (AMCA).
The AMCA, a fifth-generation fighter jet, will be equipped with two 110kN thrust class engines specifically engineered to excel in India's demanding operational environment.
Why 110kN Thrust?
- Supercruise Capability: A key feature of the AMCA is its ability to sustain supersonic speeds without relying on afterburners, a fuel-intensive process. The 110kN thrust engines will provide the necessary power for this supercruise capability, as well as to support the aircraft's radar and avionics systems.
- Adaptability to Harsh Conditions: India's hot and humid climate poses a significant challenge for fighter jet engines, often resulting in a loss of power. The AMCA's engines are being designed to withstand temperatures reaching 50 degrees Celsius (122 degrees Fahrenheit) without compromising performance.
The Need for Indigenous Development
The specific thrust-to-weight ratio required for the AMCA is not commonly found in engines produced by global manufacturers.To address this, India's Gas Turbine Research Establishment (GTRE), a division of the DRDO, is spearheading the development of a bespoke engine for the AMCA program.
This effort involves collaboration with foreign Original Equipment Manufacturers (OEMs) to integrate cutting-edge technology and ensure reliability.
Future-Proofing the AMCA
The engine is not only designed to meet current requirements but also to accommodate future advancements.With a dry core thrust capacity of 75kN, the engine can be scaled up to deliver higher thrust outputs, allowing for upgrades and modifications in the future.
This scalability ensures that the AMCA remains at the forefront of fighter jet technology for years to come.
