Abstract

The Aeronautical Development Agency (ADA), Bangalore has co-ordinated the successful indigenous development of the Indian Light Combat (LCA), now named 'Tejas', The Tejas is counted among the most advanced combat aircraft in the world, incorporating the latest state-of-the art aircraft systems. The TEJAS requires ten high performance regenerative heat exchangers for its Environmental Control Systems (ECS) and Secondary Power Systems (SPS). In order to reduce the heat load on the primary heat exchanger (PHE) in the ECS, ADA has a plan to introduce a pre-cooler upstream of it in the existing system. It performs the function of cooling the hot bleed air drawn from the engine before it enters the primary heat exchanger. ADA has sponsored a project to Propulsion Division, NAL to estimate the thermal performance of pre-coolers to validate the design and for certification.
