DRDO successfully conducts the maiden flight-test of indigenous Power Take off Shaft

The Defence Research & Development Organization (DRDO) has successfully conducted the maiden flight-test of Power Take off Shaft (PTO Shaft) was conducted on Light Combat Aircraft (LCA Tejas) Limited Series Production (LSP) – 3 aircraft in Bengaluru on March 14, 2023.

The PTO shaft is indigenously designed and developed by Combat Vehicles Research & Development Establishment (CVRDE), Chennai of DRDO.

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

With this successful test, the DRDO has achieved a greater technological feat by realisation of complex high-speed rotor technology which only few countries have achieved.

The Power Take off Shaft was designed with unique innovative patented ‘Frequency Spanning Technique’ which enables it to negotiate different operating engine speeds.

The light weight high speed, lubrication free PTO shaft transmits higher power between aircraft engine gear box and Aircraft Mounted Accessory Gear Box while accommodating misalignments that arise in the drive line.

Aeronautical Development Agency, Centre for Military Airworthiness and Certification, Directorate General of Aeronautical Quality Assurance and Hindustan Aeronautics Limited teamed along with CVRDE to achieve this.

As of now, the PTO shaft technology has already been transferred to Godrej & Boyce, Mumbai and Lakshmi Technology and Engineering, Coimbatore.
