DRDO successfully conducts flight test of indigenous Power Take off Shaft on LCA Tejas in Bengaluru

Defence Research and Development Organisation (DRDO) has successfully conducted a maiden flight-test of the Power Take off (PTO) Shaft on Light Combat Aircraft (LCA Tejas) Limited Series Production (LSP) -3 aircraft in Bengaluru. The PTO shaft is indigenously designed and developed by the Combat Vehicles Research & Development Establishment (CVRDE), Chennai of Defence Research and Development Organisation (DRDO).

Meanwhile, Defence Minister Rajnath Singh has complimented the DRDO, PSUs and the Industry and said that the successful realisation of the PTO shaft is another major milestone towards ‘Aatmanirbhar Bharat’. In a statement,



the Defence Ministry said, the PTO shaft, which is a critical component in the aircraft, will support the requirements of future fighter aircraft and their variants and offers competitive cost and reduced time of availability.

The PTO shaft was designed with a unique innovative patented ‘Frequency Spanning Technique’ which enables it to negotiate different operating engine speeds. The lightweight high speed, lubrication free PTO shaft transmits higher power between the aircraft engine gear box and Aircraft Mounted Accessory Gear Box while accommodating misalignments that arise in the drive line.
