Vadrevu Murthy

Degree(s):

  • Ph.D., Aerospace Engineering, Georgia Institute of Technology

Research Interests:

  • Helicopter dynamics

Recent research:

Helicopter CFD aerodynamics in the frequency domain using Euler’s equations — has potential to replace the current strip theory, semi-empirical, and potential flow with assumed numerical wakes models. that exist in the industry. Similarly, another research project dealt with the problems of real time optimal trajectory and control of unmanned Helicopters using Evolutionary (Genetic) Algorithms. This may find applications in the real world.
