Aerodynamic performances of twist morphing MAV wing / Noor Iswadi Ismail

Performing the biomimetic morphing method on a Micro Air Vehicle (MAV) wing is very challenging tasks due to the MAV wing size limitation, limited energy budgets, complicated morphing mechanism and complex aeroelastic interactions. These issues had restricted the application of morphing wing on MAV...
