Biography

Dr. J.V.R. Prasad is currently a  professor in the School of Aerospace Engineering  working in the area of flight mechanics He is a co-principal investigator in the US Army sponsored Vertical Lift Rotorcraft Center of Excellence (VLRCOE) program, the NASA sponsored URETTI program in the propulsion area and the General Electric Aircraft Engines University Strategic Alliance (GEAE-USA) program at Georgia Tech. He has extensive research and design experience in rotorcraft modeling, turbulence modeling, simulation, system identification, linear and nonlinear control theory applications, and neural networks and fuzzy logic control. Dr. Prasad  published parts of four books, thirty five refereed journal papers, one hundred and sixty  conference papers, and sixty  research project reports. He has five invention disclosures and four patents to his credit. He served as the chairman of the technical committee on handling qualities of the American Helicopter Society and as a member of the AIAA Flight Mechanics Technical Committee. He has been a member of the Editorial Board for the International Journal on Mathematical Modeling and Simulation and an Associate Editor of the Journal of the American Helicopter Society. He is member of the AIAA and a member of the AHS.

Research

Sensing and active control of aerospace systems, including:
  • Feedback control of stall in gas turbine engines for enhanced operability and performance
  • Sensing strategies for aircraft flight envelope protection, fault diagnostics and prognosis
  • Integrated methods for flight envelope protection and obstacle avoidance for autonomous UAV’s
  • Flight mechanics and control oriented modeling for next generation rotary-wing aircraft, on-blade control concepts
  • Stability and control issues of lightly loaded, auto-rotating lifting rotors in high speed forward flight
