NEW DELHI : Bharat Heavy Electricals Limited (BHEL) has received new project sanction orders from the Aeronautical Development Agency (ADA) for the development and supply of critical thermal management systems for India’s indigenous fighter aircraft programs, including the Light Combat Aircraft (LCA) Tejas Mk2) and the Advanced Medium Combat Aircraft (AMCA).
The orders further expand BHEL’s engagement with ADA, the design agency for India’s combat aircraft programs operating under the Defence Research and Development Organisation (DRDO). The latest mandates assign BHEL responsibility for the design and development of key components essential to aircraft environmental and cooling systems.
Project Scope and Technical Mandates
Under the newly awarded contracts, BHEL will develop advanced Pump Modules for the Liquid Cooling System (LCS), which forms a central part of the aircraft’s Environmental Control System (ECS). These pump modules will be integrated into both the LCA Tejas Mk2 and the fifth-generation AMCA platforms.
In addition to pump modules, BHEL has been commissioned to supply Compact Heat Exchangers and Fuel Coolers specifically for the AMCA program. These components are integral to maintaining thermal balance within high-performance fighter aircraft operating under varying flight conditions.
The Liquid Cooling System plays a critical role in regulating the temperature of avionics and onboard electronic systems. The Environmental Control System manages cockpit pressurization, air conditioning, and overall environmental stability required for safe aircraft operation.
Integration with Indigenous Fighter Programs
The LCA Tejas Mk2 represents an advanced iteration of India’s indigenous light combat aircraft, incorporating upgraded avionics, improved payload capacity, and enhanced propulsion systems. The AMCA is India’s proposed fifth-generation stealth fighter platform, designed with advanced sensor integration, electronic warfare capabilities, and next-generation propulsion architecture.
Thermal management systems are critical for both aircraft categories due to the high heat loads generated by powerful engines, AESA radars, mission computers, and electronic warfare suites. Efficient cooling systems ensure operational safety, system reliability, and sustained performance across mission profiles.
Continuity of Aerospace Manufacturing Role
The new orders build upon BHEL’s long-standing involvement in India’s aerospace and defense manufacturing ecosystem. The company’s Heavy Plates and Vessels Plant (HPVP) in Visakhapatnam has been supplying heat exchangers for the LCA Tejas program since 1996.
Prior to the current contracts, BHEL had successfully designed, manufactured, and delivered various types of Compact Heat Exchangers for earlier variants of the aircraft, including the LCA Tejas Mk1, Mk1A, and baseline Mk2 configurations.
These prior deliveries established BHEL’s technical capabilities in high-precision aerospace heat transfer systems, which now extend to the more advanced requirements of the AMCA program.
Indigenous Development and Supply Chain Impact
The development and domestic production of Pump Modules, Compact Heat Exchangers, and Fuel Coolers contribute to reducing reliance on imported aerospace subsystems. These components require precision engineering, advanced material expertise, and compliance with stringent aerospace standards.
By executing these projects in collaboration with ADA, BHEL strengthens domestic design-to-production capabilities within India’s defense sector. The partnership aligns with broader efforts to expand indigenous manufacturing capacity across critical aerospace subsystems, including propulsion support, avionics cooling, and environmental control technologies.
The latest project sanction orders mark a continuation of BHEL’s participation in advanced combat aircraft programs and reinforce its position as a supplier of specialized thermal management systems for India’s indigenous fighter platforms.
