The Defence Research and Development Organisation (DRDO) and PTC Industries have achieved a significant milestone in developing advanced turbine materials, focusing on single crystal high-pressure (HP) turbine blades and vanes. Utilizing sophisticated single crystal casting techniques, these components are engineered to withstand extreme temperatures exceeding 2500°C while enhancing performance metrics such as thrust and fuel efficiency. The indigenous efforts emphasize mastering the entire manufacturing process, from alloy design to final component delivery, thereby contributing to strategic self-reliance in aerospace. This advancement is crucial not only for future aero-engine versions like the Kaveri but also for bolstering India’s defense capabilities and its position in global aerospace manufacturing.
