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.
