Volume 8, Issue 1 , March 2011, , Pages 45-56

Abstract
  Performance characteristic of an Unmanned Air Vehicle (UAV) is investigated using a newly developed heuristic approach. Almost all flight phases of any air vehicle can be categorized into trim and maneuvering flights. In this paper, a new envelope called trim-ability envelope, is introduced and sketched ...  Read More

TIME OPTIMAL SLEW MANEUVER OF MAGNETICALLY ACTUATED LEO SATELLITES

Ali Heydari; Seid H. Dr. Pourtakdoust

Volume 5, Issue 2 , June 2008, , Pages 51-56

Abstract
  Conventional magnetic attitude control methodologies require several orbital periods to accomplish the required attitude maneuvers due to the existence of an uncontrollable axis, namely the local Earth’s magnetic field vector. Since in some attitude maneuver missions the elapsed time is of critical ...  Read More
