Comparison of Numerical Simulation Models for Open Loop Flight Simulations in the Human Centrifuge
(Wiley Online Library, 2013)
To achieve predefined Gz load profile in high G training in human centrifuge, it is necessary to determine angular velocity and acceleration of a planetary axis (centrifuge arm). Initial value problem that can not be ...
Overview of numerical methods for solving optimal control problem in guidance algorithms
(Univerzitet u Beogradu, Mašinski fakultet, 2022)
Numerical techniques for solving optimal control problems fall into two general classes: indirect methods and direct methods. In an indirect method, we rely on the Pontryagin's maximum principle and other necessary conditions ...
Multi-objective integrated optimization of horizontal-axis wind turbines
(Get It Published Verlag e.K., 2017)
Extracting energy from wind is a contemporary, still actively developing topic. When designing wind turbine blades, as the key components of the HAWT system, the greatest cost reductions can be made in aerodynamic (geometrical ...
Design of small-scale composite vertical-axis wind turbine blade
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
Although less efficient than their horizontal-axis counterparts, vertical-axis wind turbines (VAWTs) present an interesting research topic as well as a renewable energy converter with lots of potential for application in ...
Experimental measurements of the stresses in the lower link of the three-point hitch mechanism
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2018)
Agricultural machines and their implements are subjected to dynamic loads
during farm operations. Depending on the type of operation (e.g. lifting or plowing), lower links of the three-point hitch mechanism are ...
Production process of composite propeller for multirotor UAV
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
The application of composite materials in the aerospace industry has begun since the middle of the 20th century. Their use in various elements of aircraft constructions has extended over time. Primary load carrying elements ...
Water cavitation tunnel characterisation by LDV
(International Association for Hydro-Environment Engineering and Research (IAHR), 2021)
Water cavitation tunnel T-33, which exists in the Experimental Aerodynamics Laboratory of the Military Technical Institute, in Belgrade, since 1952 is presented in this paper. It is a continuous close-loop water tunnel. ...
Numerical and experimental modal analysis of aluminium and composite plates
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2019)
The paper presents the comparative analysis of the dynamic behaviour of two rectangular plates of different material, aluminium and composite. While their global geometric dimensions (length, width and thickness) are ...
Further results on modeling of bioimpedance of the human skin: calculus of non-integer order approach
(Belgrade: Serbian Scientific Society, 2012)
The fractional integro-differential operators are a generalization of integration and
derivation to non-integer order (fractional) operators [1]. Fractional calculus is the essential
analytical approach for modeling any ...
Numerical analysis of screw joint turn table and chassis of low-floor articulated bus IK218N
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2020)
Rapid growth and development of modern technologies led to increased application of innovative solutions in conceptual design and modelling in all fields of engineering. In order to answer to the increased requirements for ...
