While attending The University of Texas at Arlington where he earned a Bachelor of Science degree in Mechanical Engineering, Mr. Cherkasov worked for two years at Lockheed Martin on projects relating to missile navigation systems, the manufacturing process of missile housings, and the manufacturing process of the heat shield for the space shuttle. One of Mr. Cherkasov’s projects at Lockheed Martin involved computer programming in order to increase the efficiency of manufacturing missile navigation systems by tracking each step of the manufacturing process. Mr. Cherkasov’s undergraduate senior design project included researching the use of piezoelectric materials in conjunction with wind turbines in order to harvest electricity. The senior design project involved both the design and manufacture of a wind turbine, as well as electrical and wind tunnel testing to determine the most effective design.
