The results of his studies on tyre-pavement interaction and dynamic analysis of the frames of such vehicles have been used by industry to improve the design of scooters and utilize indigenous materials in their fabrication. He has also made significant contributions in the field of hydrostatic and hydrodynamic lubrication.  Prof. Singh has effectively linked his basic research interest to real industrial problems.

 Citation   Prof. Sukhatme has done significant work in the area of heat transfer. He has developed and tested an original theory of interfacial resistance for heat transfer during film condensation of liquid metal vapours. He has studied local and average heat transfer around circular tubes and various fin arrays under the influence of free and forced convection. He has developed rapid methods for measuring the thermal conductivity of slab insulations.

Suri, Man Mohan  (DOB: 13 January 1928),  Sp: Integrated powerpack with reverse governing techniques for diesel engine superimposed on a hydro-mechanical transmission called Suri-Transmission. Expired.

Citation   Shri Suri has developed a new concept of an integrated power pack involving reverse-governing techniques for the diesel engine superimposed on a hydromechanical transmission called Suri-Transmission. This  has resulted in substantially increasing the efficiency of diesel locomotives. Suri-Transmission achieves the mathematical peak of efficiency in transmission of power and provides means for changeover from one gear step to another, under full load and speed, without causing shock or interruption of Suri-Transmission and its various improvements are covered by  36 patent specifications in eleven major countries. The first transmission built and tested for 650 horse power in now in successful operation.

Citation   Dr Swarup guided and supervised the establishment of the Ooty Radio Telescope from the basic concept to detailed design and fabrication. The construction in all its aspects. i.e. mechanical, structural, microwave and electronics, has been entirely indigenous. This work has had considerable technological spin-offs for the development of microwave antennas in India. Dr Swarup has also investigated solar emission, in India. Dr Swarup has also investigated solar emission, pulsars and lunar occultations of extragalactic radio sources.

Wadhwa, Rajinder Pal  (DOB: 3 September 1932),  Sp: Microwave engineering; Vacuum devices; Quality & reliability; Measurements & education.  17, Deshbandhu Apartments, Kalkaji, New Delhi - 110 019.

 

Citation   Dr Wadhwa has guided research and development work in such areas as Indicator, X-ray, TV and transmitting tubes. His earlier work related to design of Crossed Field Devices which helped indigenisation of production of components in such diverse fields as Delay Lines, Pulse Transformers, Transistor Circuits, Magnetron Injection Guns, Beam Plasma and Crossed Field Interaction. His work has helped in the achievement of self-reliance through development of technical competence in areas of sophisticated technology.
