Bio

Dr. Agamemnon Crassidis is a Professor in Mechanical Engineering at the Rochester Institute of Technology. He received his B.S., M.S., and Ph.D. in Mechanical Engineering from the State University of New York at Buffalo specializing in control systems engineering and systems design and dynamics. His Ph.D. dissertation research was focused on the nonlinear control a motor-flexible beam system with nonlinear friction. Specifically, he developed and analyzed mathematical models for a slewing motor-beam system with the inclusion of nonlinear friction and extended these models to multi-link flexible robotic manipulators. He has more than 17 years of industrial experience in the areas of aerospace flight control system design; aircraft parameter identification; mathematical modeling and identification of nonlinear systems using experimental responses; systems engineering; mechanical systems design; and navigation, control, and measurements systems. Dr. Crassidis' current research focuses on the development of advanced all attitude/orientation devices, inertial movement correction algorithms, orientation and center-of-gravity estimation for aircraft, and model-free nonlinear control law development. He is the author of nearly a dozen papers on the topic of alternate next-generation inertial navigation and orientation sensing systems using advanced correction algorithms, CG estimation, and nonlinear model-free sliding-mode controller applications. He is an active member of the American Institute of Aeronautics and Astronautics serving as past Chair for the Atmospheric Flight Mechanics Technical Committee section and Academic Director for NUAIR (operator of the Northeast FAA UAS test-site).

Currently Teaching

MECE-510
3 Credits
Flight Dynamics is a three (3) credit hour, three (3) contact hour lectures to introduce the student to dynamics of aircraft flight. This course deals with the three-dimensional dynamics of aircraft, including general aircraft performance, stability and control, and handling qualities. Topics include: static and dynamic stability; longitudinal and lateral/directional control; mathematical development of rigid-body 6DOF equations-of-motion describing full range of aircraft motion; attitude dynamics and quaternion alternative; aerodynamic forming term coefficient development; linearization of nonlinear aircraft models; simulation of aircraft trajectories; aircraft system modes; and aircraft handling qualities introduction.
MECE-511
3 Credits
Orbital Mechanics is a three (3) credit hour, three (3) contact hour lectures to introduce the student to mechanics of orbits. This course introduces orbital mechanics and space flight dynamics theory with application for Earth, lunar, and planetary orbiting spacecraft. Content includes: historical background and equations of motion, two-body orbital mechanics, orbit determination, orbit prediction, orbital maneuvers, lunar and interplanetary trajectories, orbital rendezvous and space navigation. The two-body orbital mechanics problem, first approximation to all exploration orbits or trajectories, is covered in full detail. Students develop computer based simulations using Matlab of orbital mechanics problems including a final mission project simulation from Earth to Mars requiring a number of orbit phases and transfers between these phases.
