Performance Evaluation of a Helicopter Main Rotor Hydraulic Control System Using Rotor Equivalent Dynamic Parameters Düzağaç, Hasan Ali; Çalışkan, Hakan; Balkan, Raif Tuna (2023-02-08)
End control damping algorithm for a stabilized gun turret system for the satisfaction of the collision avoidance requirement Yerlikaya, Ümit; Balkan, Raif Tuna (2021-09-01) This paper presents a collision avoidance algorithm for stabilized gun turrets and its real-time implementation. With the help of new collision avoidance algorithm, all types of turrets can be driven more efficiently and s...
Collision Free Motion Planning for Double Turret System Operating in a Common Workspace Yerlikaya, Ümit; Balkan, Raif Tuna (2021-01-01) Instead of using the tedious process of turret teaching, an off-line path planning algorithm has been developed for military turrets to improve their accuracy and efficiency. In the scope of this research, an algorithm is ...
Collision-Free Motion Planning for an Aligned Multiple-Turret System Operating in Extreme Environment Yerlikaya, Ümit; Balkan, Raif Tuna (2021-01-01) © The Author(s), 2021. Published by Cambridge University Press.Instead of using the tedious process of manual positioning, an off-line path planning algorithm has been developed for military turrets to improve their accura...
Increasing the Bandwidth Frequency by Coulomb Friction Compensation Method in Electromechanical Control Actuation Systems YERLİKAYA, ÜMİT; Balkan, Raif Tuna (2019-07-08) In this study, it is aimed to increase the bandwidth frequency of an electromechanical control actuation system by Coulomb friction compensation method. The actuation system consists of a brushless direct current motor, ba...
A Mathematical Model for Simulation of Flow Rate and Chamber Pressures in Spool Valves Afatsun, Ahmet C.; Balkan, Raif Tuna (ASME International, 2019-02-01) In this paper, a mathematical model to simulate the pressure and flow rate characteristics of a spool valve is derived. To improve the simulation accuracy, the discharge coefficient through the spool valve ports is assumed...
Identification of Viscous and Coulomb Friction in Motion Constrained Systems YERLİKAYA, ÜMİT; Balkan, Raif Tuna (2018-07-09) In this study, a simple and inexpensive method is developed in order to identify viscous and Coulomb frictions in systems with motion limitations. This method is used on a prototype. A series of tests are performed using p...
