Hyderabad: The University of Hyderabad (UoH) has developed Multistage Closed Die Forging Technology for the Production of Aircraft Main Base Plate Undercarriage Fitting Component. With Prof. K A Padmanabhan, University Chair Professor at the School of Engineering Sciences and Technology as the Principal Investigator, the project was assigned by the Aeronautical Development Agency (ADA) for producing Aircraft Main Base Plate Undercarriage Fitting Component, used in the construction of airframe of high-performance (supersonic) aircraft, through a multi-stage closed die forging process. The project was completed in partnership with MIDHANI, Ministry of Defence.

The component manufactured by this new technology has also met the objectives like uniform mechanical properties, clearly above the AMS (American Materials Standard) specified values, for the given thickness – The results fall within a narrow band with the longitudinal tensile strength marginally higher than in the other two orthogonal directions. Other characteristics are improved buy-to-fly ratio from 18.4:1 to 4:1, Shorter manufacturing cycle, achievement of structural integrity in closed-die forging that extends the design limits of the forged parts, amongst others.

The manufacturing process has been provisionally cleared by the Regional Centre for Military Airworthiness and now three production batches will have to be successfully formed at MIDHANI for final induction of this technology as a manufacturing route.
