MUMBAI, India, Aug. 8 -- Intellectual Property India has published a patent application (202441007641 A) filed by Hindustan Aeronautics Limited, Bangalore, Karnataka, on Feb. 5, 2024, for 'fatigue test rig for aero engine accessory shaft.'
Inventor(s) include Amar Singh; Joseph Shibu K; and Syed Mazhar Ahmed.
The application for the patent was published on Aug. 8, under issue no. 32/2025.
According to the abstract released by the Intellectual Property India: "Direct comparison between simple specimen shapes and real structure have revealed marked difference in fatigue life. Hence a fatigue test rig is developed for carrying out the fatigue test of real structure at the actual operating conditions. The rig involves a DC motor [010] driving a step-up gear box [030] through a low speed coupling [020] and a high speed coupling [040] is attached to the gear box shaft [050]. The high speed coupling [040] is attached to a driving gear [050] which in turn drives the testing shaft [060]. The shaft [060] drives the blower wheel [080] which draws air [100] through the casing [070] mounted heat exchanger [090] to cool the engine oil to the desired level allowing continuous operation for long hours and the air goes out [110] through the opening in the casing [070]."
