The Application of the Root Locus Method for the Design of Pitch Controller of an F-104A Aircraft
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
This paper presents an application of the root locus technique for the design of a feedback control system of an F-104A aircraft. The analysis of the longitudinal aircraft stability was performed for the jingle Input Single ...
Dynamic Response of Mobile Elevating Work Platform under Wind Excitation
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
This paper deals with the possibility of aerodynamic instability occurrence in the mobile elevating work platform (MEWP) structure. The vibrations of the structure excited by the von Karman street and the movement induced ...
An Approach to the Optimization of a Thin-walled Z-beam
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
One approach to the optimization of a thin-walled open section Z-beam subjected to bending and to the constrained torsion is considered. For given loads, material and geometrical characteristics the problem is reduced to ...
Effectivity of Hypergeometric Function Application in the Numerical Simulation of the Helicopter Rotor Blades Theory
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
Efficiency and justification of hypergeometric functions application in achieving simple formulas used in numerical simulation of helicopter rotor blades theory are presented in this paper. Basic equations of stream field ...
Investigations of combustion process in stove fired on biomass
(Assoc. of Mechanical Eng. and Technicians of Slovenia, 2005)
The aim of the investigation was to make some reconstructions on the existing stove used for cooking and baking and to obtain the combined cooker-boiler which will fulfill the demands of European standard EN 12815. ...
Exponential tracking control of an electro-pneumatic servo motor
(Strojniski Vestnik/Journal of Mechanical Engineering, 2008)
According to the fundamental importance of the tracking theory on technical systems, the main goal of this paper is a further development of the theory and the application of the tracking, especially to the practical ...
Safe Operation of Welded Structure with Cracks at Elevated Temperature
(Strojniski Vestnik/Journal of Mechanical Engineering, 2008)
The fatigue crack growth rate parameters and conditions for abrupt fracture of thick joint in steel at room and operating temperature were analysed. Fatigue cracks generated from sharp weld defects are initial cracks that ...
Optimization of the Unloading Bridge Working Cycle
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
This paper presents one of the possible ways of optimization of unloading bridge working cycle i.e. minimization of: energy consumption, material dissipation during the grab discharging, rope incline angle etc. Optimization ...
Improved solution approach for aerodynamics loads of helicopter rotor blade in forward flight
(Strojniski Vestnik/Journal of Mechanical Engineering, 2008)
This paper presents the numerical model developed for rotor blade aerodynamics loads calculation. The model is unsteady and fully three-dimensional. Helicopter blade is assumed to be rigid, and its motion during rotation ...
Analysis of the Sailplane Final Approaches Performed by Cosine-Law Speed Variations
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
High lift-to-drag ratios of the contemporary sailplanes make them the most energy efficient flying vehicles. On the other hand, this capability may become their serious disadvantage during the landing, if their aerodynamic ...
