A view of the Rotor Telemetry System

Gas Turbine Research Establishment (GTRE), Bangalore, has designed and developed a 12-channel Rotor-Telemetry System for strain and temperature measurement for fan rotor components of Kaveri Gas Turbine Engine. It operates at a speed of more than10,000 rpm and a temperature of about 1000 C. Transfer of data is achieved at 3 Mbps with 400 Mhz RF link (UHF) and PSK modulation. The problems associated with contact wear and signal noise have been removed enabling signal acquisition which was hitherto not feasible. Design and application of this telemetry system has direct impact on monitoring health of the engine and fatigue life assessment of critical fan bladed rotor assembly. It can serve as a role model for all the future high speed strain measurement efforts of aerospace and automotive companies.

Indigenous Unmanned Air Vehicle (UAV) Nishant has been developed by Aeronautical Development Establishment (ADE), Bangalore, as the nodal agency. DEAL, Dehradun, RDE(Engrs), Pune, and ADRDE, Agra, have contributed in the development of the major sub-systems. Indigenous Unmanned Air Vehicle has completed 100thflight in June 2005 and is poised for limited series of production.

The Nishant has already undergone user trial and was successfully demonstrated to the users. Recently concluded flight trials were witnessed by senior officers from the Army including DCOAS (P&S), DCOAS (IS& T), DG (Arty), ADG (Arty), and ADG (WE).
