Mohammad hossein Moghimi Esfandabadi; Mohammad Hassan Djavareshkian

Volume 8, Issue 2 , June 2024, , Pages 13-25

  This research investigates the effect of fence on wingtip vortices and control surfaces in a bird-like aircraft using numerical methods. In designing and placing the fence, average dimensions extracted from wing root vortices at different angles of attack have been used. In addition, the fence with specified ...  Read More

Robust H∞ Control Design for Thrust Vectoring System of a UAV

Hojat Taei; Ali Aboutalebiyan

Volume 6, Issue 1 , June 2022, , Pages 17-28

  The design of a controller for a thrust vector control system of UAV has been studied through the robust  H∞ control method. In the first, the governing space-state equations of the system have been derived using the bond graph approach. Then, the critical performance parameters of the system ...  Read More

Improving the Aerodynamic Performance of Radial Gas Microturbine with Double Curvature Blades

Reza Aghaei Togh; Marziyeh Ahmadi; Mohamadhasan Nobakhti

Volume 4, Issue 4 , February 2021, , Pages 21-30

  This research aims to improve aerodynamic performance of a radial gas microturbine from input to output, so that the best case can be selected. In this work, ANSYS CFX software was used. First, using one-dimensional model, different states were investigated and the best mode was selected. Then, by solving ...  Read More
