R&D Dynamics was founded in 1990. The company founder Dr. Giri Agrawal pioneered the design and development of high speed rotating machines supported on air/gas foil bearings for the Air cycle machine in the 70 and 80 while working at Honeywell and Hamilton Sundstrand. He has been cited as the ather of the Hamilton Sundstrand Air Bearing Program. The foil bearing designs developed by Dr. Agrawal are used even today for air cycle machines of all modern civil and military aircraft. Dr. Agrawal vision for the new company was to extend foil bearing technology to rotating machines other than air cycle machines, and that is the mission of R&D Dynamics Corporation.
Today R&D Dynamics is a leading provider of Green Technology helping reduce industrial energy consumption through more efficient air conditioning systems and by providing vital components for fuel cells around the world
R&D Dynamics is also manufacturer of a product called a Turboexpander. It is generally used in the oil and gas industry but they have found a way it may also be of use in the hydogen economy.
