Magneto-Rheological Damper Landing Gear System
Depending on the different sink speeds, angles of attack and masses;aircraft landing gears could face a wide range of impact conditions which may possibly cause structural damage or failure.
Thus, in hard landing scenarios, the landing gear must absorb sufficient energy in order to minimize dynamic stress on the aircraft airframe.
Magneto-rheological (MR) fluids have received recent attraction as their rheological properties can be continuously
controlled using magnetic or electric field and they are not sensitive to the contaminants and the temperature variation and also require lower powers.
This thesis focuses on modeling of a MR damper for landing gear system and analysis of semi-active controller to
attenuate dynamic load and landing impact.
Controlled performance of the simulated MR landing gear system is demonstrated and compared with that of passive system.
